conclusion text: Beyond the Board's finding that Engineer A's retention as an expert witness for the contractor was unethical, the ethical violation was complete at the moment Engineer A accepted the contractor's retainer — not at the moment any confidential information was actually disclosed or used. The switching-sides prohibition operates as an absolute structural bar, meaning that Engineer A's subsequent pledge to produce an independent report, or any subjective intention to compartmentalize government-acquired knowledge, could not cure the conflict once the adverse engagement was accepted. The ethical harm inheres in the structural position itself: an engineer who has investigated a dam failure on behalf of one party and then accepts a retainer from the directly adverse party in the same matter has already betrayed the duty of loyalty and trust owed to the former client, regardless of subsequent conduct. This conclusion reinforces that the prohibition is deontological in character — it does not depend on a showing of actual harm, actual disclosure, or bad faith.

conclusion number: 102
conclusion text: The Board's conclusion also implies, though does not explicitly state, that Engineer A bore an independent and proactive obligation to disclose the prior government retention to the contractor before accepting the adverse engagement — and that failure to make such disclosure constitutes a separate ethical violation distinct from the switching-sides prohibition itself. Even if one were to hypothesize a scenario in which the switching-sides prohibition could somehow be overcome (for example, through informed consent of all interested parties as contemplated by Section III.4.b), the absence of proactive disclosure would independently undermine the integrity of the engagement. An engineer who accepts a retainer from an adverse party without first disclosing the prior conflicting engagement deprives the prospective client of the information necessary to make an informed decision, deprives the former client of the opportunity to withhold consent, and deprives the adjudicative proceeding of the transparency required for forensic expert testimony to serve its legitimate function. The ethical framework therefore imposes a disclosure obligation that is logically prior to and independent of the consent-prerequisite analysis.

conclusion text: The Board's conclusion further implies that the contractor's motivation in seeking to retain Engineer A — specifically, to exploit Engineer A's privileged access to the government's investigative findings and strategy — is itself an ethically relevant factor that Engineer A was obligated to recognize and act upon before accepting the engagement. An engineer exercising the professional judgment required by the objectivity and loyalty principles should have recognized that the contractor's interest in retaining a former government investigator of the very same dam failure was structurally inseparable from the value of that engineer's confidential government access. Accepting such a retainer, even if Engineer A subjectively believed the engagement was legitimate, constitutes a failure of the adverse retention motivation awareness obligation. This analysis also reveals a structural impossibility: Engineer A could not simultaneously honor the confidentiality obligation owed to the government and provide the contractor with the full, uncontaminated expert analysis the contractor was entitled to expect, meaning the objectivity principle and the confidentiality principle were in irreconcilable tension the moment the adverse retainer was accepted. The ethical prohibition therefore extends beyond the expert witness role narrowly construed and would apply equally to any consulting capacity in the same matter, because the source of the conflict is the confidential knowledge held, not the formal title of the engagement.

conclusion number: 201
conclusion text: In response to Q101: Engineer A's obligation to disclose the prior government retention arose at the earliest moment Engineer A was approached by the contractor — before any retainer agreement was signed and before any substantive discussion of the contractor's claim occurred. The ethical obligation to disclose is not merely a procedural courtesy but a substantive prerequisite to informed consent under Section III.4.b. Failure to proactively disclose constitutes an independent ethical violation separate from the switching-sides prohibition itself. Even if the switching-sides prohibition were somehow waived or inapplicable, the failure to disclose the prior adverse relationship would independently violate Engineer A's duties of candor and transparency to prospective clients. The contractor cannot make an informed decision about retention — and the former client cannot exercise its consent rights — if Engineer A withholds the material fact of the prior government engagement. Silence in this context is not neutral; it is an affirmative misrepresentation by omission of a conflict that is directly material to the legitimacy of the engagement.

The ethical prohibition is not grounded solely in the secrecy of specific data points but in the integrity of the professional relationship itself and the structural advantage Engineer A gained by having been inside the government's investigative process. Even if every factual finding Engineer A produced for the government were later published, Engineer A would still retain privileged knowledge of the government's analytical priorities, the weaknesses the government identified in its own case, the investigative paths not pursued, and the strategic framing of the evidence — none of which is captured in published reports. Furthermore, the prohibition under Section III.4.b is relationship-based, not information-based: it attaches to the fact of the prior adverse representation in the same matter, not merely to the continued secrecy of specific documents. Only if the matter itself were so remote in time that no reasonable connection to the current proceeding could be established — a threshold not met here — might the passage of time become relevant, and even then former client consent would remain the operative cure.

conclusion text: In response to Q103: The contractor's motivation in retaining Engineer A — specifically to exploit Engineer A's privileged access to government investigative strategy and findings — is itself an ethically relevant factor that Engineer A was obligated to recognize and act upon before accepting the engagement. An engineer serving as a forensic expert is not a passive instrument of the retaining party; the engineer bears independent professional obligations that include recognizing when a retention is structured to weaponize a prior confidential relationship. When the circumstances of the approach make it apparent that the contractor's primary interest is in what Engineer A learned while working for the government rather than in Engineer A's independent technical expertise, Engineer A is on constructive notice that acceptance would constitute a betrayal of the former client. The fact that Engineer A may have subjectively believed the retention was legitimate does not exculpate the engineer, because the ethical standard is objective: a reasonable engineer in Engineer A's position would have recognized the structural impropriety. Acceptance under these circumstances compounds the ethical violation by making Engineer A complicit in the contractor's attempt to convert a confidential professional relationship into a litigation advantage.

conclusion text: In response to Q104: The ethical prohibition is not narrowly confined to the expert witness role and extends to any capacity in which Engineer A might serve the contractor in this matter, including as a non-testifying consulting expert. The structural conflict arises from the relationship and the confidential access, not from the specific professional role Engineer A would occupy. A consulting expert who does not testify but who advises the contractor on technical strategy, helps frame deposition questions for government witnesses, or assists in evaluating the government's expert reports would be deploying the same privileged knowledge in the same adverse manner as a testifying expert. The harm to the former client — the government — is equivalent regardless of whether Engineer A appears on the witness stand. Section III.4.b's prohibition on participating in or representing an adverse party in the same matter encompasses advisory participation, not merely formal testimonial participation. Any narrower reading would allow the switching-sides prohibition to be circumvented through the simple expedient of designating the conflicted engineer as a non-testifying consultant.

conclusion text: In response to Q201: Engineer A cannot credibly claim to offer objective expert testimony for the contractor when that objectivity is structurally undermined by prior confidential access to the opposing party's investigative findings and strategy. The Objectivity Principle and the Loyalty Obligation are not merely in tension here — they are mutually exclusive in this specific factual configuration. Objectivity in expert witness testimony requires that the expert's analysis be derived from independent evaluation of the evidence, uncontaminated by privileged knowledge of the opposing party's internal deliberations. Engineer A's prior government engagement means that any analysis Engineer A produces for the contractor will inevitably be shaped — consciously or unconsciously — by knowledge of what the government found, what the government considered significant, and where the government perceived weaknesses in its own position. This is not a conflict that can be managed through procedural safeguards such as information screens or pledges of independence; it is a structural impossibility. The Objectivity Principle, properly understood, therefore reinforces rather than conflicts with the Loyalty Obligation: genuine objectivity in this matter is unattainable for Engineer A precisely because of the prior loyalty relationship.

conclusion text: In response to Q202: The Confidentiality Principle and the Objectivity Principle are not merely in tension for Engineer A — they create an irresolvable dilemma that independently bars acceptance of the contractor's retainer. If Engineer A honors the confidentiality obligation to the government, Engineer A must withhold from the contractor's legal team the full scope of what Engineer A knows about the government's investigative findings, analytical conclusions, and strategic vulnerabilities. This means the contractor cannot receive the complete, uncontaminated expert analysis it is entitled to expect from a retained expert. Conversely, if Engineer A provides the contractor with the full benefit of Engineer A's knowledge and expertise — as the contractor's retainer implicitly demands — Engineer A necessarily deploys confidential government information in an adverse proceeding. There is no middle path that satisfies both obligations simultaneously. This structural impossibility is itself a sufficient and independent basis for concluding that Engineer A cannot ethically accept the contractor's retainer, even setting aside the switching-sides prohibition entirely.

conclusion text: In response to Q203: The sequential nature of Engineer A's engagements does not make the ethical violation less severe than the simultaneous dual-role situation in Case 76-3 — if anything, it makes certain dimensions of the violation more severe. In Case 76-3, the simultaneous dual-role created an obvious and visible conflict that any observer could identify, and the Board's remedy of resignation addressed the ongoing nature of the divided loyalty. In the present sequential case, the conflict is structurally less visible — Engineer A's government engagement has concluded — but the harm is equally real because the confidential knowledge acquired during that engagement persists indefinitely. The sequential structure may actually be more dangerous to the integrity of adversarial proceedings because it creates the misleading appearance that the prior relationship has been cleanly severed when in fact the informational and relational advantages it conferred remain fully operative. The 1981 Code revision, by explicitly addressing the sequential adverse representation scenario, reflects the profession's recognition that the sequential structure required its own categorical prohibition rather than reliance on the resignation remedy developed for simultaneous conflicts in Case 76-3.

conclusion text: In response to Q204: The 1981 Code revision does not create genuine ambiguity about the governing standard — it clarifies and codifies a prohibition that was already implicit in the pre-existing loyalty and confidentiality obligations. The progressive tightening of the Code through the 1981 revision should be understood not as a retroactive imposition of a stricter standard on conduct that was previously permissible, but as an explicit articulation of a principle that the profession's ethical foundations had always required. The Board's analysis of the present case under the post-1981 standard is therefore not retroactively unfair to Engineer A; rather, the 1981 revision simply removed any residual ambiguity that a sophisticated engineer might have exploited to argue that sequential adverse representation was permissible under the prior Code. Even under the pre-1981 standard, the combination of loyalty obligations, confidentiality duties, and the general prohibition on conduct harmful to the profession would have pointed toward the same conclusion. The 1981 revision's primary practical effect is to eliminate the need for case-by-case inference and to establish a clear, prospective rule that engineers can apply with certainty.

conclusion text: In response to Q301: From a deontological perspective, Engineer A's duty of loyalty and non-betrayal to the U.S. government as a former client was violated at the moment of accepting the contractor's retainer, entirely independent of whether any confidential information was subsequently disclosed. Deontological ethics evaluates the moral quality of actions by reference to the duties they fulfill or violate, not by reference to their consequences. The duty of loyalty to a former client in the same matter is a categorical obligation: it prohibits adverse participation regardless of outcome. Engineer A's acceptance of the contractor's retainer constituted a betrayal of the trust relationship that the government reposed in Engineer A when it shared confidential investigative information and strategy. The pledge to produce an independent report, the absence of any proven disclosure of specific confidential findings, and any other consequentialist considerations are irrelevant to the deontological assessment. The violation was complete and morally significant the moment Engineer A agreed to serve an adverse party in the same matter, because that agreement was itself an act of disloyalty to the former client.

conclusion text: In response to Q302: From a consequentialist perspective, the harms generated by Engineer A's acceptance of the contractor's retainer substantially and decisively outweigh any benefit the contractor might derive from Engineer A's specialized knowledge. The harms are systemic and institutional: erosion of public trust in the integrity of government forensic investigations, chilling of future government willingness to share sensitive investigative findings with retained experts, undermining of the adversarial proceeding's fairness by allowing one party to benefit from the opposing party's confidential deliberations, and degradation of the professional norm that forensic engineering expertise is offered on the basis of independent analysis rather than privileged access. These harms extend far beyond the immediate parties and affect the entire ecosystem of public infrastructure forensic investigation. The benefit to the contractor — access to an expert with firsthand knowledge of the dam failure — is real but not unique: other qualified forensic engineers without the conflict could have provided equivalent or superior independent analysis. The consequentialist calculus therefore strongly reinforces the deontological conclusion: Engineer A should not have accepted the retainer.

conclusion text: In response to Q303: From a virtue ethics perspective, Engineer A failed to demonstrate the professional integrity, impartiality, and trustworthiness expected of a forensic expert witness. A virtuous forensic engineer is one whose character disposes them to recognize conflicts before they arise, to prioritize the integrity of the professional relationship over financial opportunity, and to understand that the expert witness role carries obligations to the adversarial system as a whole — not merely to the retaining party. A person of genuine professional integrity would have recognized immediately upon being approached by the contractor that the prior government engagement created an insuperable conflict, would have disclosed that conflict proactively, and would have declined the retainer without needing to be compelled by a code provision. The fact that Engineer A accepted the retainer — and apparently did so without apparent hesitation or proactive disclosure — suggests a failure of the virtuous dispositions that the profession demands of forensic experts. The virtue ethics analysis also highlights that the contractor's motivation in seeking Engineer A's retention was itself a signal that a virtuous engineer should have recognized and acted upon: being sought out specifically because of privileged access to an opposing party's confidential work is not a mark of professional distinction but a warning of ethical peril.

conclusion text: In response to Q304: From a deontological perspective, the ethical violation was complete at the moment Engineer A accepted the contractor's retainer, and no subsequent conduct — including pledging to produce an independent report, refraining from disclosing specific confidential findings, or conducting a genuinely independent technical analysis — could retroactively cure or mitigate the violation. The switching-sides prohibition under Section III.4.b is a categorical rule, not a standard of care that admits of degrees of compliance. Once Engineer A agreed to serve an adverse party in the same matter without the former client's consent, the prohibition was violated in its entirety. Subsequent good conduct does not undo the breach of duty that occurred at acceptance; it merely affects the severity of downstream consequences, not the existence of the violation itself. This analysis is consistent with the Board's implicit treatment of the independent report pledge as a non-cure: the pledge addresses the symptom — potential disclosure of confidential information — while leaving the underlying violation — the adverse representation itself — entirely intact.

conclusion text: In response to Q401: It would have been ethically permissible for Engineer A to accept the contractor's retainer if the contractor's claim had involved a completely different dam project unrelated to the government investigation Engineer A had conducted. The switching-sides prohibition and the former client adversarial participation prohibition are both matter-specific: they attach to the same matter in which the prior confidential relationship arose. If the contractor's claim concerned a different dam, a different failure event, and a different set of technical and factual issues, Engineer A's prior government engagement would not have generated the structural conflict that makes acceptance impermissible here. Engineer A's general expertise in dam failure forensics would remain available to any client in any unrelated matter. The ethical constraints identified in this case are therefore not a blanket prohibition on Engineer A serving contractors who have disputes with the government; they are a targeted prohibition on Engineer A serving any party adverse to the government in the specific matter — the dam failure investigation — in which Engineer A acquired confidential knowledge as the government's retained expert.

conclusion text: In response to Q402: The ethical outcome would have differed materially if Engineer A had proactively sought and obtained the U.S. government's informed consent before accepting the contractor's retainer, because Section III.4.b explicitly identifies consent of all interested parties as the operative exception to the adverse participation prohibition. However, for that consent to satisfy the requirements of Section III.4.b, it would need to be genuinely informed and freely given — not merely formal or coerced. The government's consent would need to be accompanied by full disclosure of the nature and scope of Engineer A's proposed engagement for the contractor, the specific confidential information Engineer A possessed, and the potential uses to which that information might be put. Additionally, the consent would need to be accompanied by enforceable undertakings by Engineer A regarding the boundaries of the contractor engagement — for example, explicit agreement not to advise the contractor on matters directly derived from confidential government findings. Even with consent, Engineer A would face the structural impossibility identified in Q202: the inability to simultaneously honor confidentiality obligations and provide the contractor with uncontaminated expert analysis. Consent therefore cures the formal violation of Section III.4.b but does not resolve the deeper structural conflict that makes Engineer A's objectivity unattainable in this matter.

conclusion text: In response to Q403: Under the pre-1981 Code standard applicable in Case 76-3, Engineer A's acceptance of the contractor's retainer would likely still have been ethically problematic, though the analysis would have required more inferential reasoning from general loyalty and confidentiality principles rather than application of an explicit sequential adverse representation rule. The 1981 Code revision represents a meaningful and substantive tightening of the standard: it moved the profession from a regime in which sequential adverse representation required case-by-case ethical inference to one in which it is categorically prohibited absent consent. Had Case 76-3 arisen after the 1981 revision, the Board's analysis would have been simpler and more categorical — the resignation remedy identified in Case 76-3 for simultaneous conflicts would have been supplemented by the explicit sequential prohibition for post-termination adverse engagements. The 1981 revision therefore does not merely restate existing law; it closes a gap that the pre-1981 framework left open to argument, and it reflects the profession's considered judgment that the sequential structure of adverse representation is sufficiently dangerous to the integrity of professional relationships to warrant explicit categorical prohibition.

conclusion text: In response to Q404: Full disclosure of the prior government retainer to the contractor before acceptance would not cure the ethical conflict, and the contractor's motivation in retaining Engineer A specifically because of that prior access would itself constitute an independent bar to acceptance. Transparency about the conflict is a necessary but not sufficient condition for ethical acceptance: it satisfies the disclosure obligation but does not satisfy the consent requirement of Section III.4.b, which requires the consent of the former client — the government — not merely the disclosure to the new client. Moreover, when the contractor's motivation is explicitly to exploit Engineer A's privileged access to government investigative strategy and findings, Engineer A's acceptance — even with full disclosure to the contractor — transforms Engineer A into an instrument of the very harm the switching-sides prohibition is designed to prevent. A retention that is transparent about its improper purpose is not thereby rendered proper. Engineer A's professional obligations require not merely disclosure but declination when the proposed engagement is structured to weaponize a prior confidential relationship, regardless of how openly that purpose is acknowledged by the retaining party.

conclusion text: The tension between the Objectivity Principle for expert witness independence and the Loyalty Obligation to the former client U.S. Government was resolved decisively in favor of loyalty, but not by subordinating objectivity as a lesser value. Rather, the Board's reasoning reveals that the two principles are structurally incompatible in this fact pattern: Engineer A cannot credibly claim to offer objective expert testimony for the contractor when the very foundation of that testimony was built on privileged access to the opposing party's investigative findings and strategy. Objectivity, properly understood, requires freedom from structural conflicts — not merely a subjective pledge of impartiality. Because Engineer A's prior government engagement permanently contaminated the epistemic basis of any subsequent analysis in the same matter, the Objectivity Principle itself demands declination of the contractor's retainer. The case thus teaches that loyalty and objectivity are not genuinely in tension here; they converge on the same outcome. An expert who has switched sides cannot be objective, and an expert who cannot be objective has no legitimate claim to the expert witness role.

conclusion text: The Confidentiality Principle protecting government-acquired specialized knowledge and the Objectivity Principle for expert witness independence do not merely tension against each other — they create a structural double bind that makes Engineer A's acceptance of the contractor's retainer ethically untenable from two independent directions simultaneously. If Engineer A honors the Confidentiality Principle and withholds government-acquired findings and strategic insights from the contractor's analysis, then Engineer A's expert testimony is incomplete and potentially misleading, violating the duty of candor owed to the contractor and the tribunal. If Engineer A instead provides the contractor with the full benefit of all knowledge acquired during the government engagement — including confidential investigative strategy and findings — then Engineer A has breached the Confidentiality Principle owed to the former client. There is no path through this double bind that satisfies both principles simultaneously. The case teaches that when a confidentiality obligation and an objectivity obligation are structurally irreconcilable in a given engagement, the engineer's only ethically compliant option is to decline the engagement entirely rather than attempt to navigate an impossible middle course.

conclusion text: The Switching Sides Prohibition operates in this case as a lexically prior principle that forecloses engagement with the other principles rather than being weighed against them. The Board's analysis, informed by the 1981 Code revision and the precedent of Case 76-3, establishes that the Former Client Adversarial Participation Prohibition under Section III.4.b is not a factor to be balanced against Engineer A's potential contributions to the contractor's claim or the adversarial system's interest in access to specialized expertise. Instead, it functions as an absolute threshold constraint: once Engineer A was retained by the U.S. government to investigate the dam failure, the same-matter adverse retainer by the contractor became categorically impermissible absent the government's informed consent, regardless of the sequential rather than simultaneous nature of the engagements, regardless of Engineer A's pledge to produce an independent report, and regardless of whether any specific confidential finding was actually disclosed. The case teaches that the 1981 Code revision deliberately elevated the switching-sides prohibition from a contextual consideration to a near-absolute rule precisely because the harms it prevents — betrayal of client trust, contamination of adversarial proceedings, and erosion of public confidence in forensic engineering — are structural and not remediable by individual pledges of good conduct. Principle prioritization in this case is therefore not achieved through balancing but through categorical exclusion: loyalty and confidentiality obligations to the former client operate as side-constraints that remove the engagement from the domain of permissible action before any weighing of competing considerations can begin.

DP1
type: DecisionPoint
type: NamedIndividual
decision point id: DP1
decision question: Should Engineer A accept the contractor's retainer as expert witness against the U.S. government in the same dam failure matter, notwithstanding that the prior government engagement has been formally completed and compensated?
focus: Engineer A has completed and been paid in full for forensic investigation work performed on behalf of the U.S. government in a dam failure matter. A contractor who has filed a claim against the government arising from the same dam project subsequently approaches Engineer A and offers a retainer to serve as an expert witness. Engineer A must decide whether to accept or decline this adverse engagement, knowing that the prior government engagement gave Engineer A access to confidential forensic findings, investigative methodologies, and strategic analysis belonging to the government.
option1: Refuse the contractor's offer of retention as expert witness in the dam failure claim, recognizing that the 1981 revision of NSPE Code Section III.4.b bars adverse participation using specialized knowledge gained for a former client regardless of whether the prior engagement has been formally terminated and fully compensated.
option2: Accept the contractor's retainer on the condition of pledging to conduct a wholly separate and independent forensic analysis, relying on the formal termination of the government engagement and full payment as sufficient cure of any conflict, and on pre-1981 precedent such as Case 76-3 as justification.
option3: Accept the contractor's retainer without restriction or condition, treating the completed government engagement as a closed matter that creates no continuing ethical obligations, and proceeding to provide expert testimony based on firsthand knowledge of the dam failure facts.

DP2
type: DecisionPoint
type: NamedIndividual
decision point id: DP2
decision question: Is Engineer A obligated to proactively disclose the prior government retention to the contractor at the earliest moment of approach, before any retainer agreement is executed, and does failure to do so constitute an independent ethical violation?
focus: Before or upon being approached by the contractor, Engineer A must decide whether to proactively disclose the prior government retention to the contractor. The contractor is soliciting Engineer A specifically because of Engineer A's prior involvement in the government's forensic investigation of the same dam failure, and the contractor's motivation is to exploit Engineer A's privileged access to the government's investigative strategy and findings. Engineer A must determine whether disclosure of the prior engagement is an independent ethical obligation that arises before any retainer agreement is signed.
option1: At the first moment of contact with the contractor, affirmatively disclose the prior government retention in the same dam failure matter, explain the nature and scope of the confidential access gained, and decline the retainer on the basis that the conflict is irremediable — without waiting for the contractor to inquire.
option2: Refrain from volunteering information about the prior government engagement unless the contractor specifically asks, treating disclosure as a reactive rather than proactive obligation and allowing the retainer negotiation to proceed without Engineer A raising the conflict.
option3: Accept the contractor's retainer first and subsequently disclose the prior government engagement during the course of the engagement, treating post-acceptance disclosure as sufficient to satisfy any transparency obligation.

DP3
type: DecisionPoint
type: NamedIndividual
decision point id: DP3
decision question: Was Engineer A required to seek and obtain the U.S. government's explicit consent before accepting any engagement for the contractor in the same dam failure matter, and does forgoing consent-seeking constitute an independent ethical violation?
focus: Engineer A must decide whether to seek the U.S. government's explicit consent before accepting any adverse engagement for the contractor in the same dam failure matter. The 1981 revision of NSPE Code Section III.4.b establishes that specialized knowledge acquired during a prior engagement may not be used adversarially without the former client's explicit consent. Engineer A has not sought such consent and must determine whether consent-seeking is a mandatory prerequisite or merely a procedural option.
option1: Contact the U.S. government as former client, fully disclose the contractor's solicitation and the nature of the proposed adverse engagement, and obtain explicit written consent before taking any steps toward accepting the contractor's retainer — recognizing that Section III.4.b makes such consent a mandatory prerequisite, not a discretionary courtesy.
option2: Proceed without seeking the government's consent, treating the formal termination and full payment of the prior engagement as having extinguished all continuing obligations to the former client, and relying on pre-1981 precedent under which post-engagement adverse participation was permissible without consent.
option3: Accept the contractor's retainer first and subsequently notify the U.S. government of the adverse engagement, treating retroactive notification as functionally equivalent to the consent prerequisite established by Section III.4.b.

DP4
type: DecisionPoint
type: NamedIndividual
decision point id: DP4
decision question: Does Engineer A's ethical obligation to decline the contractor's engagement extend to all capacities — including non-testifying consulting expert roles — or is the prohibition narrowly confined to the testifying expert witness function?
focus: Engineer A must assess whether the ethical prohibition on adverse participation extends beyond the specific role of testifying expert witness to encompass any capacity in which Engineer A might serve the contractor — including as a non-testifying consulting expert. The contractor may argue that a purely consulting role, in which Engineer A does not testify and does not directly present government-acquired findings, avoids the switching-sides prohibition. Engineer A must determine whether the prohibition is role-specific or categorical.
option1: Refuse to serve the contractor in any role — whether as testifying expert, non-testifying consulting expert, technical advisor, or reviewer — recognizing that the confidential forensic knowledge gained during the government engagement would inevitably inform any technical contribution Engineer A makes to the contractor's claim, regardless of the formal label attached to the engagement.
option2: Decline the testifying expert witness role but accept a behind-the-scenes consulting engagement for the contractor, reasoning that the switching-sides prohibition applies specifically to adversarial testimony and that a consulting role in which Engineer A does not appear before a tribunal avoids the ethical violation.
option3: Accept a narrowly scoped engagement limited to reviewing publicly available documents and published reports about the dam failure, reasoning that work confined to public information does not implicate the confidential government findings and therefore falls outside the scope of the prohibition.

DP5
type: DecisionPoint
type: NamedIndividual
decision point id: DP5
decision question: Would the ethical prohibition on Engineer A's adverse participation for the contractor be eroded or extinguished if Engineer A's government engagement had concluded years earlier and the confidential forensic findings had since become publicly available through litigation discovery or published government reports?
focus: Engineer A must evaluate whether the passage of time and the public availability of formerly confidential government forensic findings — through litigation discovery or published reports — would alter the ethical calculus and potentially permit adverse participation for the contractor. Engineer A may reason that once confidential information enters the public domain, the confidentiality rationale for the switching-sides prohibition is extinguished and the prohibition no longer applies.
option1: Recognize that the switching-sides prohibition is not eroded by the passage of time or the public availability of formerly confidential findings, because the prohibition is grounded not only in confidentiality but also in the irremediable structural compromise of Engineer A's objectivity — which persists regardless of whether the underlying findings are now publicly known — and decline the contractor engagement on that independent basis.
option2: Treat the public availability of formerly confidential government forensic findings as extinguishing the confidentiality rationale for the prohibition, and accept the contractor's retainer on the ground that Engineer A's testimony would be based solely on publicly available information rather than privileged government knowledge.
option3: Apply a temporal exception to the switching-sides prohibition, reasoning that after a sufficient number of years the professional relationship with the former client has sufficiently attenuated that the loyalty and confidentiality obligations no longer bar adverse participation in the same matter.

capabilitystatement: Engineer A required the capability to recognize that the termination of the government engagement did not bring the situation within the principle that loyalties are not divided when a prior relationship has ended — because that principle applies to concurrent dual roles without confidential information transmission, not to sequential forensic engagements where government-side confidential materials had already been received and processed.

Resignation as Prerequisite for Adverse Advocacy Permissibility Applied to Case 76-3 Precedent
type: ResignationasPrerequisiteforAdverseAdvocacyPermissibilityPrinciple
type: NamedIndividual
appliedto: Engineer A Dam Failure Forensic Investigation Engineer
balancingwith: Confidentiality Principle
balancingwith: Former Client Adversarial Participation Prohibition
concept category: Principle
concreteexpression: In Case 76-3, the Board held that an engineer simultaneously serving as county advisor could ethically oppose the county's position only by first resigning from the advisory role; this resignation-clearance mechanism was the operative ethical remedy for active dual-side participation, but it was insufficient under the 1981 Code when specialized knowledge had already been acquired

importance: high
interpretation: Resignation clears the appearance-of-impropriety concern arising from simultaneous dual-role service, but does not and cannot clear the specialized-knowledge confidentiality concern that Section III.4.b addresses; the two ethical problems require different remedies
invokedby: Case 76-3 precedent
invokedby: NSPE Board of Ethical Review
principleclass: Resignation as Prerequisite for Adverse Advocacy Permissibility Principle
sourcetext: if he chose to oppose that position on behalf of an adverse party, he could ethically do so by first resigning from his role as advisor to the county
tensionresolution: The present case demonstrates that resignation is a necessary but not sufficient condition for ethical adverse engagement when specialized knowledge has been acquired — the additional requirement of former client consent under Section III.4.b cannot be satisfied by resignation alone
textreferences: Given the unambiguous language of Case 76-3 noted above, it would appear that Engineer A could ethically represent the interests of the contractor as an expert witness in its claim against the government for additional compensation.
textreferences: However, there is one important distinction between Case 76-3 and the case presented here.
textreferences: Under the facts of this case, Engineer A was paid in full for his services to the government and apparently was no longer retained by the government and was free to oppose its position on behalf of an adverse party.
textreferences: if he chose to oppose that position on behalf of an adverse party, he could ethically do so by first resigning from his role as advisor to the county
