Causal Chains (5)
NESS test analysis: Necessary Element of Sufficient Set

Causal Language: The city attorney attempted to explain these factors to the members of the city council in a recent public forum, but the city council voted to proceed with the proposed change to the ordinance.

Necessary Factors (NESS):
  • Proposal formally pending before the city council
  • City attorney's awareness of the safety, standards, and state law concerns
  • A public forum providing an opportunity to address the council
Sufficient Factors:
  • Combination of pending unsafe proposal + city attorney's professional duty to advise the council + public forum venue
Counterfactual Test: Without the proposal being introduced before the council, the city attorney would have had no occasion to explain the safety and legal concerns
Responsibility Attribution:

Agent: City council member (proposal sponsor)
Type: indirect
Within Agent Control: Yes

Causal Sequence:
  1. Legislative Proposal Introduction
    Council member introduces the ordinance amendment for council consideration
  2. Public Concern Explanation
    City attorney explains at a public forum that the change is unsafe, contrary to standards, and contrary to state law

Causal Language: While it may not be necessary for Engineer A to formally report the situation to a public authority since public authorities are aware of the facts and circumstances

Necessary Factors (NESS):
  • City attorney's explanation of the safety, standards, and state law concerns
  • Public forum with city council members and public authorities present
Sufficient Factors:
  • City attorney's public explanation at the forum was itself enough to inform the public authorities of the facts and circumstances
Counterfactual Test: Without the city attorney's public explanation, public authorities may not have been aware of the facts and circumstances, making formal reporting by Engineer A necessary

Causal Language: Engineer A has an obligation to further report the situation to appropriate local, state, and/or federal authorities to ensure that relevant engineering standards are consistent with protecting the public health, safety, and welfare.

Necessary Factors (NESS):
  • Approval of an ordinance change contrary to engineering standards and state law
  • Engineer A's knowledge of the unsafe nature of the change
  • Engineer A's professional ethical obligation to hold paramount public health, safety, and welfare
Sufficient Factors:

Counterfactual Test: Had the council rejected the change or required an engineering study, Engineer A's obligation to escalate the report to higher authorities would not have been triggered in the same way
Responsibility Attribution:

Type: direct
Within Agent Control: Yes

Causal Sequence:
  1. Legislative Vote Decision
    Council votes to proceed with the change despite explained concerns
  2. Ordinance Change Approval
    Ordinance change moves forward, creating an ongoing threat to public safety
  3. Public Authority Awareness
