http://proethica.org/ontology/intermediate#DividedLoyaltyIrreconcilabilityinDual-ClientEngineeringRoles
Applied to
Engineer A's sequential retention by plaintiff's attorney and then defense attorney in the same proceeding
Balancing with
Absolute Loyalty Prohibition to Former Clients
Engineer Professional Autonomy and Independence Preservation Principle
Concrete expression
The Board applied the divided loyalty analysis from BER Cases 76-3 and 74-2 to distinguish permissible dual engagement (where loyalties are not divided) from impermissible engagement (where the engineer is effectively on both sides of a divided issue) — finding Engineer A's situation analogous to BER Case 76-3 where the engineer was on both sides
Confidence
0.93
Importance
high
Interpretation
The Board distinguished BER Case 74-2 (part-time municipal consultants whose loyalties were not divided) from BER Case 76-3 (engineer on both sides of a divided issue) and found Engineer A's situation fell squarely in the latter category — his sequential retention by opposing parties in the same proceeding created an irreconcilable division of loyalty
Invoked by
Engineer A Forensic Expert Switching Sides
Tension resolution
The irreconcilability of divided loyalty prevailed; the argument that Engineer A's loyalties were no longer divided because he had terminated the first engagement was rejected because the ethical obligation to the former client persisted
Source Evidence
Source text
the key distinction between BER Case 74-2 and BER Case 76-3 was that in BER Case 74-2 the engineer's loyalties were not divided, whereas in BER Case 76-3 Engineer A is seen to be on both sides of the divided issue.
Text references
It may be argued, as was stated in the earlier BER Case 74-2, that Engineer A's loyalties under these facts were not divided because he had terminated his relationship with plaintiff's attorney.
the key distinction between BER Case 74-2 and BER Case 76-3 was that in BER Case 74-2 the engineer's loyalties were not divided, whereas in BER Case 76-3 Engineer A is seen to be on both sides of the divided issue.
we must recognize that while Engineer A may not currently have a professional relationship with a former client, he still has an ethical obligation to that client
