Causal Chains (8)
NESS test analysis: Necessary Element of Sufficient Set

Causal Language: Engineer A is retained by the U.S. government to study the causes of a dam failure.

Necessary Factors (NESS):
  • Occurrence of the dam failure requiring causal investigation
  • Government's need for engineering expertise to study the failure
  • Engineer A's availability and willingness to accept the retainer
Sufficient Factors:
  • Dam failure + government's decision to investigate + Engineer A's acceptance of the engagement
Counterfactual Test: Without the dam failure, there would have been no investigation to retain Engineer A for; the retainer would not have occurred
Responsibility Attribution:

Agent: U.S. government (retaining party) and Engineer A (accepting party)
Type: shared
Within Agent Control: Yes

Causal Sequence:
  1. Dam Failure
    A dam on the project fails, creating a need to determine causes
  2. Government Investigation Need
    The U.S. government seeks engineering expertise to study the failure
  3. Government Retainer Acceptance
    Engineer A accepts the government retainer to study the causes of the dam failure

Causal Language: In July 1981, the Code of Ethics was revised. Section III.4.b. amended and refined the older Code Section 7 to read: "Engineers shall not, without the consent of all interested parties, participate in or represent an adversary interest in connection with a specific project or proceeding in which the engineer has gained a particular specialized knowledge on behalf of a former client or employer."

Necessary Factors (NESS):
  • NSPE's decision to revise the Code of Ethics

Causal Language: In addition, we have no doubt that the expert testimony offered by Engineer A in a legal proceeding would constitute "particular, specialized knowledge gained on behalf of a former client or employer."

Causal Language: Under the revised Code section it is clear that Engineer A's action was in violation of Section III.4.b. There is nothing in the record to indicate that Engineer A was given the consent of his former client, the U.S. government, to represent the interests of the contractor in its claim against the government for additional compensation.

Causal Language: Case 76-3 was decided under the 1976 Code of Ethics which made no mention of an engineer's ethical obligation to refrain from representing an adverse interest in a proceeding.

Necessary Factors (NESS):
  • Section III.4.b being in effect at the time of Engineer A's conduct
  • Engineer A's adverse representation without consent
  • Board's application of the revised standard rather than Case 76-3's 1976 Code
Sufficient Factors:
  • Revised Code effectivity + Engineer A's non-consented adverse retention
Counterfactual Test: Under the 1976 Code and Case 76-3 reasoning alone, 'it would appear that Engineer A could ethically represent the interests of the contractor'; without the revision, no violation would have been found
Responsibility Attribution:

Agent: NSPE (for the standard); Engineer A (for the violating conduct)
Type: indirect
Within Agent Control: No

Causal Sequence:
  1. Code Revision Adoption
    NSPE adopts the July 1981 revision creating Section III.4.b
  2. Revised Code Effectivity
    Section III.4.b becomes the governing standard for adverse-interest representation
  3. Adverse Expert Retention Acceptance
    Engineer A accepts adverse retention without consent of all interested parties
  4. Ethical Violation Finding
    The Board applies Section III.4.b and finds the conduct unethical

Causal Language: The development company then called the engineer as an expert witness at the zoning hearing. The engineer testified in support of the zoning petition.

Necessary Factors (NESS):
  • Engineer's second retainer agreement with the developer
  • Developer's zoning petition and the county's adverse engineering reports
  • Developer calling the engineer as an expert witness
Sufficient Factors:
  • Second retainer + zoning dispute + developer's call for testimony + engineer's choice to testify while still advising the county
Counterfactual Test: Had the engineer not accepted the second retainer, or had he first resigned as county advisor, he would not have appeared as a paid advocate on both sides of the public policy issue
Responsibility Attribution:

Agent: Engineer in Case 76-3
Type: direct
Within Agent Control: Yes

Causal Sequence:
  1. Concurrent Second Retainer Acceptance
    Engineer enters second retainer with the developer while retained by the county
  2. Zoning Petition Filing
    The developer files a petition to rezone a substantial area of the county
  3. County Adverse Reports
    The county files engineering reports recommending denial of the rezoning
