Step 4: Full View

Beyond the Board's finding that Engineer A had an affirmative obligation to step forward and immediately advise Attorney X, the scope of that obligation is not exhausted by disclosure to the retaining attorney alone. Because the erroneous report was already circulating as a functional instrument in active settlement negotiations - negotiations that could produce a binding resolution affecting the injured party, the defendant, and potentially the public - Engineer A's truthfulness and public welfare obligations extend, at minimum, to ensuring that the corrected analysis reaches every decision-maker whose reliance on the original report could produce a materially unjust outcome. If Attorney X declines to act on the corrected findings, Engineer A's obligations do not terminate at the boundary of the attorney-client relationship. The adversarial context non-exemption principle confirms that the adversarial structure of litigation does not convert Engineer A into an advocate whose duty of accuracy is owed only to the retaining party. Accordingly, Engineer A must be prepared to escalate disclosure - including, if necessary, to the court or opposing counsel - if Attorney X suppresses or ignores the correction, because allowing an inaccurate forensic report to remain the operative technical basis for a settlement is functionally equivalent to making a material misrepresentation of fact to the legal process itself.

Engineer A's obligation to disclose the data inaccuracy does not, at the initial stage, extend automatically to the court, the opposing party, or the public. The primary and immediate duty runs to Attorney X as the retaining attorney, who is the appropriate professional intermediary capable of determining how the corrected findings must be handled within the legal process. However, this limitation is conditional: if Attorney X refuses to act on the corrected information or instructs Engineer A to suppress it, Engineer A's obligations escalate beyond the attorney-client channel. At that point, the erroneous report's continued circulation in settlement negotiations constitutes an ongoing misrepresentation of technical fact that Engineer A cannot passively permit. The public welfare paramount principle and the non-deception constraint together foreclose Engineer A's silence as a permissible option regardless of Attorney X's instructions. The harm to third parties - including the injured client who may receive a settlement calibrated to inaccurate causation findings, and the defendant who may settle based on inflated liability - gives the disclosure obligation a systemic dimension that transcends the bilateral attorney-engineer relationship.

If settlement negotiations had already concluded and a settlement agreement had been signed before Engineer A discovered the data inaccuracy, Engineer A's ethical obligations would differ materially in scope and direction from the pre-settlement disclosure duty. In the post-settlement scenario, disclosure to Attorney X alone would be insufficient because the legal proceeding has produced a binding outcome that may have been materially shaped by the inaccurate report. Engineer A's obligations would extend to considering whether the court, the opposing party, or other relevant authorities need to be informed, particularly if the settlement was judicially approved or if the inaccurate findings influenced a court record. The public welfare paramount principle and the non-deception constraint do not terminate upon settlement conclusion; they persist as long as the erroneous report remains part of a legal record capable of influencing future proceedings, establishing precedent, or being relied upon in related litigation. The post-settlement context also raises the question of whether Engineer A has an obligation to prepare and make available the corrected analysis, independent of whether any party requests it, so that the accurate technical record exists and can be accessed if the matter is reopened or if related claims arise. This represents a broader and more complex disclosure obligation than the pre-settlement duty, which is satisfied by immediate disclosure to Attorney X.

Engineer A's obligation to disclose the data inaccuracy does not, at the initial stage, extend automatically to the court, the opposing party, or the public. The primary and immediate duty runs to Attorney X as the retaining attorney, who is the appropriate professional intermediary capable of determining how the corrected findings must be handled within the legal process. However, this limitation is conditional: if Attorney X refuses to act on the corrected information or instructs Engineer A to suppress it, Engineer A's obligations escalate beyond the attorney-client channel. At that point, the erroneous report's continued circulation in settlement negotiations constitutes an ongoing misrepresentation of technical fact that Engineer A cannot passively permit. The public welfare paramount principle and the non-deception constraint together foreclose Engineer A's silence as a permissible option regardless of Attorney X's instructions. The harm to third parties - including the injured client who may receive a settlement calibrated to inaccurate causation findings, and the defendant who may settle based on inflated liability - gives the disclosure obligation a systemic dimension that transcends the bilateral attorney-engineer relationship.

If Attorney X, upon being informed of the data inaccuracy, instructs Engineer A to suppress the corrected findings and proceed with the original report during settlement negotiations, that instruction does not constitute a legitimate exercise of the attorney's authority over the forensic engagement. The faithful agent obligation that Engineer A owes to Attorney X is bounded by the NSPE Code's truthfulness and non-deception provisions, and those provisions are not waivable by client instruction. Engineer A's role as a forensic expert is defined by objectivity and technical integrity, not by advocacy for the retaining party's litigation position. Compliance with Attorney X's suppression instruction would transform Engineer A from an objective expert into an instrument of misrepresentation, violating the adversarial context non-exemption principle, the honesty in professional representations principle, and the error acknowledgment obligation simultaneously. Under these circumstances, Engineer A would be ethically required to refuse the instruction, and if Attorney X persisted, Engineer A would need to consider withdrawal from the engagement. Withdrawal does not, however, extinguish Engineer A's underlying obligation to ensure the corrected findings are not suppressed in a manner that corrupts the legal process, particularly if the erroneous report remains in active use.

The Board's emphasis on the critical importance of the timing - that Attorney X was in the middle of negotiations - implicitly recognizes that temporal position carries independent ethical weight, but the Board did not fully articulate why. The pre-settlement discovery window is ethically distinct from a post-settlement discovery in the following respect: before settlement is concluded, disclosure of the corrected findings preserves the possibility that the legal process will reach a result grounded in accurate technical facts. After settlement is concluded, that corrective opportunity is foreclosed, and the harm - whether to the injured party who may have accepted an inadequate recovery, or to the defendant who may have paid an inflated settlement - becomes irreversible without further legal proceedings. This asymmetry means that Engineer A's obligation during the pre-settlement window is not merely urgent in a practical sense but is categorically more demanding in an ethical sense: it is the last moment at which Engineer A's professional action can prevent, rather than merely remediate, the harm caused by the inaccurate report. The temporal urgency constraint is therefore not simply a procedural consideration but a substantive ethical amplifier that increases the weight of the disclosure obligation relative to any competing considerations, including the faithful agent obligation toward Attorney X.

The timing of Engineer A's discovery - after submission but before settlement conclusion - does carry independent ethical weight beyond what would exist in a post-settlement scenario. The pre-settlement window represents a period during which the erroneous report is actively operative: it is shaping negotiating positions, influencing assessments of liability magnitude, and potentially driving a settlement figure that neither party would have accepted had accurate data been available. This active operativeness creates a heightened urgency because the harm is prospective and preventable. Engineer A's disclosure at this stage can interrupt the causal chain before it produces an unjust outcome. By contrast, post-settlement discovery would involve a harm already crystallized, where disclosure obligations would shift in character - becoming less about prevention and more about remediation, potentially requiring engagement with the court or opposing counsel rather than solely with Attorney X. The temporal distinction therefore carries genuine ethical significance: the pre-settlement context imposes an affirmative obligation of immediate disclosure precisely because the corrective action remains capable of preventing the misrepresentation from producing its full harmful effect. Delay within this window - even brief delay - compounds the ethical violation because each passing moment of negotiation conducted on the basis of the inaccurate report deepens the misrepresentation's influence on the outcome.

The interaction between the Error Acknowledgment and Corrective Disclosure Obligation and the Forensic Report Integrity in Active Litigation Context principle reveals that these two principles are not genuinely in tension in this case, despite the superficial appearance of conflict. A concern might be raised that immediate disclosure of the data inaccuracy could disrupt ongoing negotiations before a corrected analysis is prepared, thereby compromising the integrity of the legal process. However, the principle synthesis that emerges from this case is that forensic report integrity is achieved through accuracy and transparency, not through the uninterrupted continuation of negotiations premised on flawed data. The integrity of active litigation is not served by allowing an inaccurate expert report to remain operative; it is served by ensuring that the legal process operates on truthful technical foundations. Accordingly, the temporal urgency constraint - which the Board identifies as critically important given that negotiations were ongoing - does not create a conflict between these principles but instead reinforces their alignment: the sooner the error is disclosed, the sooner the legal process can be corrected, and the more fully forensic report integrity is preserved. This synthesis also answers the counterfactual question about post-settlement discovery: the pre-settlement timing does not merely create urgency, it creates a qualitatively distinct opportunity to prevent the legal process from being concluded on false premises - an opportunity that carries independent ethical weight and that the Code's provisions on truthfulness and error acknowledgment require Engineer A to seize immediately.

The Board's conclusions address Engineer A's disclosure obligation but leave unexamined a logically prior question: whether Engineer A's original investigative methodology was itself deficient in a manner that constitutes a separate and independent ethical violation. If the data inaccuracy resulted from Engineer A's failure to apply appropriate professional diligence during the investigation - for example, by relying on unverified sources, failing to cross-check critical inputs, or omitting standard quality-control procedures - then the ethical analysis cannot be confined to the post-discovery disclosure obligation. The intellectual honesty obligation and the objectivity and truthfulness constraint both apply prospectively to the conduct of the investigation, not merely retrospectively to the correction of its outputs. A finding that Engineer A's methodology was deficient would mean that Engineer A violated the Code at the moment of submitting the original report, not only at the moment of discovering the error and failing to disclose it. The Board's silence on this point may reflect the absence of facts establishing methodological deficiency, but the analytical framework should make explicit that the disclosure obligation and the investigative competence obligation are distinct, that both are enforceable under the Code, and that satisfying the former does not retroactively cure a violation of the latter.

The Board's analysis focuses on Engineer A's disclosure obligation upon discovering the error but does not examine whether Engineer A's original investigative methodology was itself deficient. This is a distinct and independently significant ethical question. If the data inaccuracy resulted from Engineer A's failure to apply appropriate investigative rigor - for example, relying on unverified secondary data sources, failing to cross-check critical inputs, or omitting standard validation steps - then the initial submission of the report may itself constitute a violation of the objectivity and truthfulness obligations under the Code, separate from the subsequent disclosure failure. The error acknowledgment obligation under Code provision III.1.a. encompasses not merely the duty to correct discovered errors but also the implicit duty to employ methodologies sufficiently rigorous to minimize the probability of material error in the first instance. A forensic expert who submits conclusions based on data that reasonable professional diligence would have identified as suspect has not merely made an innocent mistake - they have potentially violated the professional report integrity standard at the point of original submission. The Board's silence on this dimension leaves open whether Engineer A's conduct prior to discovery was itself ethically adequate, and that silence should not be read as implicit exoneration of the original methodology.

Beyond the Board's finding that Engineer A had an affirmative obligation to step forward and immediately advise Attorney X, the scope of that obligation is not exhausted by disclosure to the retaining attorney alone. Because the erroneous report was already circulating as a functional instrument in active settlement negotiations - negotiations that could produce a binding resolution affecting the injured party, the defendant, and potentially the public - Engineer A's truthfulness and public welfare obligations extend, at minimum, to ensuring that the corrected analysis reaches every decision-maker whose reliance on the original report could produce a materially unjust outcome. If Attorney X declines to act on the corrected findings, Engineer A's obligations do not terminate at the boundary of the attorney-client relationship. The adversarial context non-exemption principle confirms that the adversarial structure of litigation does not convert Engineer A into an advocate whose duty of accuracy is owed only to the retaining party. Accordingly, Engineer A must be prepared to escalate disclosure - including, if necessary, to the court or opposing counsel - if Attorney X suppresses or ignores the correction, because allowing an inaccurate forensic report to remain the operative technical basis for a settlement is functionally equivalent to making a material misrepresentation of fact to the legal process itself.

The Board's framework implicitly resolves the tension between the faithful agent obligation and the truthfulness obligation in favor of truthfulness, but it does so without articulating the limiting principle that governs the faithful agent role in forensic expert contexts. That limiting principle is this: the faithful agent obligation is a role-specific duty that operates within the boundaries set by the Code's overarching provisions, and it cannot be invoked to justify any action - or inaction - that would require Engineer A to make, or allow to persist, a material misrepresentation of fact. Attorney X retained Engineer A not as an advocate but as a forensic expert whose value to the litigation derives precisely from the reliability and accuracy of the technical analysis. An engineer who suppresses a known data inaccuracy to preserve a client's negotiating position is not acting as a faithful agent in any professionally cognizable sense; the engineer is acting as an advocate, which is a role the Code does not authorize and which the adversarial context non-exemption principle expressly forecloses. The faithful agent obligation, properly understood, requires Engineer A to serve Attorney X's legitimate professional interests - which include receiving accurate technical information necessary to make informed litigation decisions - not Attorney X's short-term tactical interests in maintaining a favorable but inaccurate evidentiary posture. Disclosure of the corrected findings is therefore not a breach of the faithful agent duty but its fulfillment.

The case resolves the tension between the Faithful Agent Obligation and the Truthfulness Obligation by establishing a clear hierarchical ordering: Engineer A's duty of loyalty to Attorney X is real and operative, but it is bounded by the non-negotiable floor of truthfulness and error correction. The faithful agent principle does not authorize Engineer A to remain silent about a discovered data inaccuracy simply because disclosure may harm the client's negotiating position. Rather, the faithful agent obligation is properly understood as requiring Engineer A to serve Attorney X's legitimate professional interests - which cannot include reliance on a report Engineer A now knows to be materially inaccurate. This case teaches that the faithful agent principle is not a trump card that overrides truthfulness; instead, it is a principle that operates within the space defined by the Code's honesty provisions. When those provisions are triggered - as they are upon discovery of a material data error - the faithful agent obligation recedes to the extent it conflicts with the duty to disclose. The resolution is not a balancing test in which client loyalty and truthfulness are weighed against each other; it is a categorical subordination of client loyalty to truthfulness in the forensic expert context.

From a consequentialist perspective, the Board's reasoning implicitly rejects the argument that the potential harm to Attorney X's client from a weakened settlement position could outweigh the obligation to disclose the data inaccuracy, but the analytical basis for that rejection deserves explicit articulation. The consequentialist calculus here does not favor suppression for two independent reasons. First, the harm to the injured party from a settlement based on inaccurate technical data is not merely the risk of an inadequate recovery; it is the harm of having the legal process produce an outcome that does not correspond to the actual facts of the case - a systemic harm that undermines the integrity of civil dispute resolution as a social institution. Second, the harm to the defendant from being compelled to negotiate a settlement on the basis of a forensic report that Engineer A knows to be inaccurate is a concrete and identifiable injury that the Code's non-deception constraint is designed to prevent. When both parties to a negotiation are relying on technical findings that the expert knows to be wrong, the settlement process is not functioning as a legitimate mechanism for resolving the dispute; it is functioning as a mechanism for laundering an error into a binding legal outcome. The consequentialist case for disclosure is therefore not merely that honesty produces better outcomes in the aggregate, but that the specific consequences of suppression in this case - harm to the defendant, potential under-recovery by the injured party, and corruption of the legal process - are all independently sufficient to require disclosure.

If Attorney X, upon being informed of the data inaccuracy, instructs Engineer A to suppress the corrected findings and proceed with the original report during settlement negotiations, that instruction does not constitute a legitimate exercise of the attorney's authority over the forensic engagement. The faithful agent obligation that Engineer A owes to Attorney X is bounded by the NSPE Code's truthfulness and non-deception provisions, and those provisions are not waivable by client instruction. Engineer A's role as a forensic expert is defined by objectivity and technical integrity, not by advocacy for the retaining party's litigation position. Compliance with Attorney X's suppression instruction would transform Engineer A from an objective expert into an instrument of misrepresentation, violating the adversarial context non-exemption principle, the honesty in professional representations principle, and the error acknowledgment obligation simultaneously. Under these circumstances, Engineer A would be ethically required to refuse the instruction, and if Attorney X persisted, Engineer A would need to consider withdrawal from the engagement. Withdrawal does not, however, extinguish Engineer A's underlying obligation to ensure the corrected findings are not suppressed in a manner that corrupts the legal process, particularly if the erroneous report remains in active use.

From a consequentialist perspective, the systemic harm to legal process integrity from permitting an inaccurate forensic report to remain operative during settlement negotiations categorically outweighs the particularized harm to Attorney X's client from a weakened negotiating position. The consequentialist calculus must account not only for the immediate parties but for the broader institutional effects: if forensic engineers were permitted - or expected - to remain silent about discovered data inaccuracies when disclosure would disadvantage their retaining client, the reliability of forensic expert testimony as an institution would be systematically degraded. Courts, opposing parties, and the public would lose the ability to trust that submitted forensic reports represent the expert's genuine and current best assessment of the technical facts. This systemic harm aggregates across all future cases in which forensic experts might face similar pressures, producing a far larger expected harm than the loss of negotiating advantage in any single case. Moreover, the consequentialist analysis must recognize that the injured client's interest in a favorable settlement is not a legitimate interest in a settlement inflated by inaccurate technical findings - it is an interest in a settlement that accurately reflects the defendant's actual liability. A settlement based on erroneous causation conclusions does not serve the injured client's genuine interests; it merely produces a number that may be higher or lower than the accurate figure, with no principled relationship to actual harm.

The Adversarial Context Non-Exemption principle and the Public Welfare Paramount principle together resolve the tension raised by the adversarial litigation setting in a decisive and instructive way: the fact that Engineer A is operating as a retained expert within an adversarial proceeding does not transform Engineer A into an advocate whose obligations are defined by the client's litigation strategy. The case establishes that the adversarial structure of settlement negotiations is ethically irrelevant to Engineer A's corrective disclosure obligation. This is significant because it forecloses a potentially tempting rationalization - that the adversarial nature of litigation creates a zone of permissible silence for retained experts who discover inconvenient facts. The principle synthesis here is that the adversarial context, rather than relaxing Engineer A's objectivity duties, actually heightens the importance of those duties, because the legal process depends on forensic experts maintaining integrity precisely when adversarial pressures are greatest. The Client Disservice Through Incomplete Reporting Prohibition reinforces this synthesis: allowing an inaccurate report to remain operative in settlement negotiations does not serve the client's genuine long-term interests, even if it appears to serve the client's short-term negotiating position. A settlement built on inaccurate forensic data is a structurally compromised outcome that disserves all parties, including Attorney X's client.

The Board's emphasis on the critical importance of the timing - that Attorney X was in the middle of negotiations - implicitly recognizes that temporal position carries independent ethical weight, but the Board did not fully articulate why. The pre-settlement discovery window is ethically distinct from a post-settlement discovery in the following respect: before settlement is concluded, disclosure of the corrected findings preserves the possibility that the legal process will reach a result grounded in accurate technical facts.

A forensic expert who submits conclusions based on data that reasonable professional diligence would have identified as suspect has not merely made an innocent mistake - they have potentially violated the professional report integrity standard at the point of original submission. The Board's silence on this dimension leaves open whether Engineer A's conduct prior to discovery was itself ethically adequate, and that silence should not be read as implicit exoneration of the original methodology.

A concern might be raised that immediate disclosure of the data inaccuracy could disrupt ongoing negotiations before a corrected analysis is prepared, thereby compromising the integrity of the legal process.

From a deontological perspective, Engineer A's categorical duty of truthfulness is not contingent on the consequences of disclosure for Attorney X's client. The Kantian framework underlying the Code's truthfulness provisions treats the obligation to correct a known material misrepresentation as a duty that holds regardless of outcome. Engineer A cannot coherently universalize a maxim permitting forensic experts to suppress discovered data inaccuracies when disclosure would harm their client's negotiating position, because such a universalized maxim would destroy the epistemic foundation upon which forensic expert testimony derives its value in legal proceedings. The duty therefore runs unconditionally: Engineer A fulfilled the categorical obligation by immediately advising Attorney X, and that fulfillment is ethically correct independent of whether it weakened the settlement position. The adverse consequence to the client does not retroactively undermine the ethical correctness of the disclosure - it merely illustrates the tension between deontological duty and consequentialist preference that the Code resolves in favor of truthfulness. Critically, the deontological analysis also forecloses the faithful agent duty as a competing categorical obligation capable of overriding truthfulness: the faithful agent role is instrumental and bounded, while the truthfulness duty is foundational and unbounded within the professional ethics framework.

From a consequentialist perspective, the Board's reasoning implicitly rejects the argument that the potential harm to Attorney X's client from a weakened settlement position could outweigh the obligation to disclose the data inaccuracy, but the analytical basis for that rejection deserves explicit articulation. The consequentialist calculus here does not favor suppression for two independent reasons.

A settlement built on inaccurate forensic data is a structurally compromised outcome that disserves all parties, including Attorney X's client.

From a virtue ethics perspective, Engineer A's treatment of the corrective disclosure obligation as non-negotiable - even under the pressure of an active settlement context - is precisely the expression of the professional virtues of intellectual honesty and integrity that the forensic engineering role demands. Virtue ethics asks not merely what rule applies but what a person of excellent professional character would do. A forensic engineer of excellent character does not experience the discovery of a material data error as a strategic problem to be managed in light of client interests; they experience it as an immediate professional obligation that admits no deferral. The virtue of intellectual honesty requires Engineer A to hold the accuracy of the technical record as a value that supersedes the convenience of the current litigation posture. The virtue of integrity requires that Engineer A's external conduct - advising Attorney X immediately - be consistent with the internal recognition that the submitted report no longer represents Engineer A's genuine professional conclusions. Silence in the face of a known material inaccuracy would constitute a form of professional self-betrayal that virtue ethics identifies as a corruption of character, not merely a rule violation. The adversarial settlement context, far from providing a virtue-based justification for silence, actually heightens the demand for these virtues precisely because the pressure to remain silent is greatest.

The Board's framework implicitly resolves the tension between the faithful agent obligation and the truthfulness obligation in favor of truthfulness, but it does so without articulating the limiting principle that governs the faithful agent role in forensic expert contexts. That limiting principle is this: the faithful agent obligation is a role-specific duty that operates within the boundaries set by the Code's overarching provisions, and it cannot be invoked to justify any action - or inaction - that would require Engineer A to make, or allow to persist, a material misrepresentation of fact. Attorney X retained Engineer A not as an advocate but as a forensic expert whose value to the litigation derives precisely from the reliability and accuracy of the technical analysis. An engineer who suppresses a known data inaccuracy to preserve a client's negotiating position is not acting as a faithful agent in any professionally cognizable sense; the engineer is acting as an advocate, which is a role the Code does not authorize and which the adversarial context non-exemption principle expressly forecloses. The faithful agent obligation, properly understood, requires Engineer A to serve Attorney X's legitimate professional interests - which include receiving accurate technical information necessary to make informed litigation decisions - not Attorney X's short-term tactical interests in maintaining a favorable but inaccurate evidentiary posture. Disclosure of the corrected findings is therefore not a breach of the faithful agent duty but its fulfillment.

From a deontological perspective, Engineer A's categorical duty of truthfulness is not contingent on the consequences of disclosure for Attorney X's client. The Kantian framework underlying the Code's truthfulness provisions treats the obligation to correct a known material misrepresentation as a duty that holds regardless of outcome. Engineer A cannot coherently universalize a maxim permitting forensic experts to suppress discovered data inaccuracies when disclosure would harm their client's negotiating position, because such a universalized maxim would destroy the epistemic foundation upon which forensic expert testimony derives its value in legal proceedings. The duty therefore runs unconditionally: Engineer A fulfilled the categorical obligation by immediately advising Attorney X, and that fulfillment is ethically correct independent of whether it weakened the settlement position. The adverse consequence to the client does not retroactively undermine the ethical correctness of the disclosure - it merely illustrates the tension between deontological duty and consequentialist preference that the Code resolves in favor of truthfulness. Critically, the deontological analysis also forecloses the faithful agent duty as a competing categorical obligation capable of overriding truthfulness: the faithful agent role is instrumental and bounded, while the truthfulness duty is foundational and unbounded within the professional ethics framework.

If Engineer A had chosen to remain silent about the data inaccuracy on the grounds that the attorney-client relationship imposed a duty of confidentiality, that confidentiality rationale would not constitute a legitimate ethical defense under the NSPE Code and would represent a fundamental misapplication of the faithful agent principle. The faithful agent obligation requires Engineer A to serve Attorney X's legitimate professional interests - which include receiving accurate technical information necessary to conduct the litigation ethically and effectively - not to protect Attorney X from information that is inconvenient to the current litigation strategy. Confidentiality within the forensic expert engagement applies to the contents of the report and the attorney's litigation strategy; it does not apply to Engineer A's own professional obligation to correct a material error in Engineer A's own work product. To invoke confidentiality as a basis for suppressing a known material inaccuracy in a submitted forensic report would be to weaponize the faithful agent principle against the very truthfulness obligations that give the forensic expert role its professional legitimacy. The Code's truthfulness provisions categorically foreclose this defense: Code provision III.1.a. imposes an unqualified obligation to acknowledge errors, and Code provision III.3.a. prohibits statements containing material misrepresentations or omissions - neither provision contains a confidentiality exception that would permit Engineer A to remain silent about a discovered data inaccuracy.

The case resolves the tension between the Faithful Agent Obligation and the Truthfulness Obligation by establishing a clear hierarchical ordering: Engineer A's duty of loyalty to Attorney X is real and operative, but it is bounded by the non-negotiable floor of truthfulness and error correction. The faithful agent principle does not authorize Engineer A to remain silent about a discovered data inaccuracy simply because disclosure may harm the client's negotiating position. Rather, the faithful agent obligation is properly understood as requiring Engineer A to serve Attorney X's legitimate professional interests - which cannot include reliance on a report Engineer A now knows to be materially inaccurate. This case teaches that the faithful agent principle is not a trump card that overrides truthfulness; instead, it is a principle that operates within the space defined by the Code's honesty provisions. When those provisions are triggered - as they are upon discovery of a material data error - the faithful agent obligation recedes to the extent it conflicts with the duty to disclose. The resolution is not a balancing test in which client loyalty and truthfulness are weighed against each other; it is a categorical subordination of client loyalty to truthfulness in the forensic expert context.

The timing of Engineer A's discovery - after submission but before settlement conclusion - does carry independent ethical weight beyond what would exist in a post-settlement scenario. The pre-settlement window represents a period during which the erroneous report is actively operative: it is shaping negotiating positions, influencing assessments of liability magnitude, and potentially driving a settlement figure that neither party would have accepted had accurate data been available. This active operativeness creates a heightened urgency because the harm is prospective and preventable. Engineer A's disclosure at this stage can interrupt the causal chain before it produces an unjust outcome. By contrast, post-settlement discovery would involve a harm already crystallized, where disclosure obligations would shift in character - becoming less about prevention and more about remediation, potentially requiring engagement with the court or opposing counsel rather than solely with Attorney X. The temporal distinction therefore carries genuine ethical significance: the pre-settlement context imposes an affirmative obligation of immediate disclosure precisely because the corrective action remains capable of preventing the misrepresentation from producing its full harmful effect. Delay within this window - even brief delay - compounds the ethical violation because each passing moment of negotiation conducted on the basis of the inaccurate report deepens the misrepresentation's influence on the outcome.

If Engineer A had discovered the data inaccuracy before submitting the report rather than after, the ethical obligation to disclose - in the sense of correcting the report before submission - would have been identical in character but qualitatively less demanding in its corrective mechanics. Pre-submission discovery requires only that Engineer A revise the report to reflect accurate data before it enters the legal process; no external disclosure obligation arises because the misrepresentation has not yet been made. Post-submission discovery, by contrast, creates a qualitatively distinct and more demanding corrective obligation because the inaccurate report has already been introduced into an active legal proceeding and is being relied upon by Attorney X in negotiations. The post-submission context requires not merely internal correction but affirmative external disclosure - Engineer A must actively communicate the error to Attorney X and ensure the corrected conclusions replace the erroneous ones in the negotiating context. This distinction is ethically significant: the post-submission scenario involves an ongoing misrepresentation that Engineer A has a duty to interrupt, whereas the pre-submission scenario involves a potential misrepresentation that Engineer A has a duty to prevent. The urgency is therefore heightened in the post-submission context because each moment of inaction allows the misrepresentation to continue operating on the legal process.

The interaction between the Error Acknowledgment and Corrective Disclosure Obligation and the Forensic Report Integrity in Active Litigation Context principle reveals that these two principles are not genuinely in tension in this case, despite the superficial appearance of conflict. A concern might be raised that immediate disclosure of the data inaccuracy could disrupt ongoing negotiations before a corrected analysis is prepared, thereby compromising the integrity of the legal process. However, the principle synthesis that emerges from this case is that forensic report integrity is achieved through accuracy and transparency, not through the uninterrupted continuation of negotiations premised on flawed data. The integrity of active litigation is not served by allowing an inaccurate expert report to remain operative; it is served by ensuring that the legal process operates on truthful technical foundations. Accordingly, the temporal urgency constraint - which the Board identifies as critically important given that negotiations were ongoing - does not create a conflict between these principles but instead reinforces their alignment: the sooner the error is disclosed, the sooner the legal process can be corrected, and the more fully forensic report integrity is preserved. This synthesis also answers the counterfactual question about post-settlement discovery: the pre-settlement timing does not merely create urgency, it creates a qualitatively distinct opportunity to prevent the legal process from being concluded on false premises - an opportunity that carries independent ethical weight and that the Code's provisions on truthfulness and error acknowledgment require Engineer A to seize immediately.

From a consequentialist perspective, the Board's reasoning implicitly rejects the argument that the potential harm to Attorney X's client from a weakened settlement position could outweigh the obligation to disclose the data inaccuracy, but the analytical basis for that rejection deserves explicit articulation. The consequentialist calculus here does not favor suppression for two independent reasons. First, the harm to the injured party from a settlement based on inaccurate technical data is not merely the risk of an inadequate recovery; it is the harm of having the legal process produce an outcome that does not correspond to the actual facts of the case - a systemic harm that undermines the integrity of civil dispute resolution as a social institution. Second, the harm to the defendant from being compelled to negotiate a settlement on the basis of a forensic report that Engineer A knows to be inaccurate is a concrete and identifiable injury that the Code's non-deception constraint is designed to prevent. When both parties to a negotiation are relying on technical findings that the expert knows to be wrong, the settlement process is not functioning as a legitimate mechanism for resolving the dispute; it is functioning as a mechanism for laundering an error into a binding legal outcome. The consequentialist case for disclosure is therefore not merely that honesty produces better outcomes in the aggregate, but that the specific consequences of suppression in this case - harm to the defendant, potential under-recovery by the injured party, and corruption of the legal process - are all independently sufficient to require disclosure.

From a deontological perspective, Engineer A's categorical duty of truthfulness is not contingent on the consequences of disclosure for Attorney X's client. The Kantian framework underlying the Code's truthfulness provisions treats the obligation to correct a known material misrepresentation as a duty that holds regardless of outcome. Engineer A cannot coherently universalize a maxim permitting forensic experts to suppress discovered data inaccuracies when disclosure would harm their client's negotiating position, because such a universalized maxim would destroy the epistemic foundation upon which forensic expert testimony derives its value in legal proceedings. The duty therefore runs unconditionally: Engineer A fulfilled the categorical obligation by immediately advising Attorney X, and that fulfillment is ethically correct independent of whether it weakened the settlement position. The adverse consequence to the client does not retroactively undermine the ethical correctness of the disclosure - it merely illustrates the tension between deontological duty and consequentialist preference that the Code resolves in favor of truthfulness. Critically, the deontological analysis also forecloses the faithful agent duty as a competing categorical obligation capable of overriding truthfulness: the faithful agent role is instrumental and bounded, while the truthfulness duty is foundational and unbounded within the professional ethics framework.

From a consequentialist perspective, the systemic harm to legal process integrity from permitting an inaccurate forensic report to remain operative during settlement negotiations categorically outweighs the particularized harm to Attorney X's client from a weakened negotiating position. The consequentialist calculus must account not only for the immediate parties but for the broader institutional effects: if forensic engineers were permitted - or expected - to remain silent about discovered data inaccuracies when disclosure would disadvantage their retaining client, the reliability of forensic expert testimony as an institution would be systematically degraded. Courts, opposing parties, and the public would lose the ability to trust that submitted forensic reports represent the expert's genuine and current best assessment of the technical facts. This systemic harm aggregates across all future cases in which forensic experts might face similar pressures, producing a far larger expected harm than the loss of negotiating advantage in any single case. Moreover, the consequentialist analysis must recognize that the injured client's interest in a favorable settlement is not a legitimate interest in a settlement inflated by inaccurate technical findings - it is an interest in a settlement that accurately reflects the defendant's actual liability. A settlement based on erroneous causation conclusions does not serve the injured client's genuine interests; it merely produces a number that may be higher or lower than the accurate figure, with no principled relationship to actual harm.

The Board's emphasis on the critical importance of the timing - that Attorney X was in the middle of negotiations - implicitly recognizes that temporal position carries independent ethical weight, but the Board did not fully articulate why. The pre-settlement discovery window is ethically distinct from a post-settlement discovery in the following respect: before settlement is concluded, disclosure of the corrected findings preserves the possibility that the legal process will reach a result grounded in accurate technical facts. After settlement is concluded, that corrective opportunity is foreclosed, and the harm - whether to the injured party who may have accepted an inadequate recovery, or to the defendant who may have paid an inflated settlement - becomes irreversible without further legal proceedings. This asymmetry means that Engineer A's obligation during the pre-settlement window is not merely urgent in a practical sense but is categorically more demanding in an ethical sense: it is the last moment at which Engineer A's professional action can prevent, rather than merely remediate, the harm caused by the inaccurate report. The temporal urgency constraint is therefore not simply a procedural consideration but a substantive ethical amplifier that increases the weight of the disclosure obligation relative to any competing considerations, including the faithful agent obligation toward Attorney X.

If settlement negotiations had already concluded and a settlement agreement had been signed before Engineer A discovered the data inaccuracy, Engineer A's ethical obligations would differ materially in scope and direction from the pre-settlement disclosure duty. In the post-settlement scenario, disclosure to Attorney X alone would be insufficient because the legal proceeding has produced a binding outcome that may have been materially shaped by the inaccurate report. Engineer A's obligations would extend to considering whether the court, the opposing party, or other relevant authorities need to be informed, particularly if the settlement was judicially approved or if the inaccurate findings influenced a court record. The public welfare paramount principle and the non-deception constraint do not terminate upon settlement conclusion; they persist as long as the erroneous report remains part of a legal record capable of influencing future proceedings, establishing precedent, or being relied upon in related litigation. The post-settlement context also raises the question of whether Engineer A has an obligation to prepare and make available the corrected analysis, independent of whether any party requests it, so that the accurate technical record exists and can be accessed if the matter is reopened or if related claims arise. This represents a broader and more complex disclosure obligation than the pre-settlement duty, which is satisfied by immediate disclosure to Attorney X.

The interaction between the Error Acknowledgment and Corrective Disclosure Obligation and the Forensic Report Integrity in Active Litigation Context principle reveals that these two principles are not genuinely in tension in this case, despite the superficial appearance of conflict. A concern might be raised that immediate disclosure of the data inaccuracy could disrupt ongoing negotiations before a corrected analysis is prepared, thereby compromising the integrity of the legal process. However, the principle synthesis that emerges from this case is that forensic report integrity is achieved through accuracy and transparency, not through the uninterrupted continuation of negotiations premised on flawed data. The integrity of active litigation is not served by allowing an inaccurate expert report to remain operative; it is served by ensuring that the legal process operates on truthful technical foundations. Accordingly, the temporal urgency constraint - which the Board identifies as critically important given that negotiations were ongoing - does not create a conflict between these principles but instead reinforces their alignment: the sooner the error is disclosed, the sooner the legal process can be corrected, and the more fully forensic report integrity is preserved. This synthesis also answers the counterfactual question about post-settlement discovery: the pre-settlement timing does not merely create urgency, it creates a qualitatively distinct opportunity to prevent the legal process from being concluded on false premises - an opportunity that carries independent ethical weight and that the Code's provisions on truthfulness and error acknowledgment require Engineer A to seize immediately.

The Board's framework implicitly resolves the tension between the faithful agent obligation and the truthfulness obligation in favor of truthfulness, but it does so without articulating the limiting principle that governs the faithful agent role in forensic expert contexts. That limiting principle is this: the faithful agent obligation is a role-specific duty that operates within the boundaries set by the Code's overarching provisions, and it cannot be invoked to justify any action - or inaction - that would require Engineer A to make, or allow to persist, a material misrepresentation of fact. Attorney X retained Engineer A not as an advocate but as a forensic expert whose value to the litigation derives precisely from the reliability and accuracy of the technical analysis. An engineer who suppresses a known data inaccuracy to preserve a client's negotiating position is not acting as a faithful agent in any professionally cognizable sense; the engineer is acting as an advocate, which is a role the Code does not authorize and which the adversarial context non-exemption principle expressly forecloses. The faithful agent obligation, properly understood, requires Engineer A to serve Attorney X's legitimate professional interests - which include receiving accurate technical information necessary to make informed litigation decisions - not Attorney X's short-term tactical interests in maintaining a favorable but inaccurate evidentiary posture. Disclosure of the corrected findings is therefore not a breach of the faithful agent duty but its fulfillment.

If Engineer A had chosen to remain silent about the data inaccuracy on the grounds that the attorney-client relationship imposed a duty of confidentiality, that confidentiality rationale would not constitute a legitimate ethical defense under the NSPE Code and would represent a fundamental misapplication of the faithful agent principle. The faithful agent obligation requires Engineer A to serve Attorney X's legitimate professional interests - which include receiving accurate technical information necessary to conduct the litigation ethically and effectively - not to protect Attorney X from information that is inconvenient to the current litigation strategy. Confidentiality within the forensic expert engagement applies to the contents of the report and the attorney's litigation strategy; it does not apply to Engineer A's own professional obligation to correct a material error in Engineer A's own work product. To invoke confidentiality as a basis for suppressing a known material inaccuracy in a submitted forensic report would be to weaponize the faithful agent principle against the very truthfulness obligations that give the forensic expert role its professional legitimacy. The Code's truthfulness provisions categorically foreclose this defense: Code provision III.1.a. imposes an unqualified obligation to acknowledge errors, and Code provision III.3.a. prohibits statements containing material misrepresentations or omissions - neither provision contains a confidentiality exception that would permit Engineer A to remain silent about a discovered data inaccuracy.
