A licensed professional is sometimes called as an expert witness to provide an opinion to a court or arbitration tribunal.

Which of the following phrases would best define an expert witness?

  1. A professional who is hired to use their knowledge and expertise to defend a client.
  2. An educated individual holding a P.Eng or P.Geo called on to confirm or disprove testimony at a trial.
  3. A subject matter expert who is hired to assess a case and provide an opinion on a defendant's culpability.
  4. A person qualified with special knowledge and expertise called on to provide an unbiased opinion at a trial.

Answer(s): D

Explanation:

NPPE materials describe an expert witness as an individual who possesses specialized knowledge, skill, training, or experience beyond that of the average person and who is qualified by the court or tribunal to provide opinion evidence. A key principle emphasized in NPPE references is that the expert witness's primary duty is to the court or tribunal, not to the party who retained them. This duty requires independence, objectivity, and impartiality.

Option D correctly reflects this principle by emphasizing that the expert witness provides an unbiased opinion. NPPE documents explicitly state that expert witnesses must not act as advocates for either side and must not tailor their opinions to benefit the client who retained them. Their role is to assist the decision-maker in understanding technical matters by providing fair, objective, and independent opinions.

Option A is incorrect because defending a client is the role of legal counsel, not an expert witness. Option B is inaccurate because holding a P.Eng or P.Geo designation alone does not define an expert witness, nor is the expert's role limited to confirming or disproving testimony. Option C is incorrect because expert witnesses do not determine guilt or culpability; that responsibility lies with the court or tribunal.

Therefore, option D best aligns with NPPE guidance on the definition and ethical obligations of an expert witness.



Company ABC is bidding on a large petrochemical study. They submit their bid based on the assumption that they can use a simple, straightforward method with inexpensive equipment. The bidders competing against Company ABC assume that a complicated method requiring expensive equipment will be needed. After Company ABC wins the bid, they discover that an error in their proposed method means that it will not work.
Which of the following statements best applies to this situation?

  1. Company ABC can revoke its bid without having to forfeit any bid bond or bid deposit.
  2. Company ABC must prove obvious and material error in order to avoid the formation of a contract.
  3. Company ABC does not have any choice and must form a contract with the buyer based on the new assumptions.
  4. Company ABC must wait until the award of the contract to inform the buyer.

Answer(s): B

Explanation:

NPPE materials covering contract law and tendering emphasize the principles governing bids and contractual formation. Once a compliant bid is submitted, it may constitute an offer that becomes binding upon acceptance. However, NPPE references recognize the legal doctrine of unilateral mistake in tendering, which may allow a bidder to avoid contract formation if specific conditions are met.

To withdraw a bid without penalty, the bidder must demonstrate that an obvious and material error occurred and that the error fundamentally affected the bid. NPPE study materials explain that the mistake must be significant, relate to a key assumption, and be discoverable or apparent to the owner at the time of bid evaluation. If these conditions are satisfied, the bidder may avoid contract formation.

Option B correctly reflects this principle. Option A is incorrect because bids generally cannot be revoked without consequence unless legal conditions for mistake are met. Option C is incorrect because the law does not automatically force contract formation when a material error exists. Option D is incorrect because prompt disclosure is required; waiting until contract award may eliminate the bidder's ability to rely on mistake.

Thus, option B best applies under NPPE contract law principles.



Ethics is the study of

  1. morality
  2. history
  3. duties
  4. laws

Answer(s): A

Explanation:

NPPE materials define ethics as the systematic study of moral principles, values, and conduct that govern individual and professional behavior. Ethics addresses questions of right and wrong, good and bad, fairness, responsibility, and integrity. In the professional context, ethics provides the foundation for Codes of Ethics that guide engineers and geoscientists in making decisions that protect the public, clients, employers, and the profession.

Option A correctly identifies ethics as the study of morality. NPPE references consistently use morality as the core concept underlying ethical reasoning, emphasizing moral judgment, ethical decision-making, and professional responsibility.

Option B is incorrect because history concerns past events and developments, not moral principles. Option C is incorrect because duties are obligations derived from ethical frameworks but are not themselves the study of ethics. Option D is incorrect because laws are rules enforced by the state,

whereas ethics often go beyond legal requirements and may impose higher standards of conduct.

NPPE materials stress that ethical obligations may exist even when no legal rule applies and that professionals must act ethically, not merely legally. Therefore, option A is the correct answer.



A professional member works at an industrial plant that is using an incorrect method of disposing of toxic waste at its mine site.
Which of the following initial actions would be best for the member to take?

  1. Inform local government of the situation.
  2. Seek advice from the provincial professional association.
  3. Contact the media to ensure that the company is held accountable.
  4. Inform company managers about the situation and offer to assist in developing a new disposal plan.

Answer(s): D

Explanation:

NPPE materials emphasize that the primary ethical duty of engineers and geoscientists is the protection of the public interest, including environmental protection. However, the Codes of Ethics also stress a structured and responsible approach when addressing unsafe or unethical practices. The initial step is to act internally and professionally by informing the employer and attempting to resolve the issue using technical expertise.

Option D aligns with NPPE guidance, which states that professionals should first bring concerns to the attention of appropriate levels of management and offer constructive solutions. This approach demonstrates professionalism, loyalty, and good faith while still fulfilling the duty to protect the public and the environment.

Option A is premature, as escalation to authorities is appropriate only if internal efforts fail. Option B may be appropriate later, but NPPE guidance indicates that internal resolution should be attempted first. Option C is inappropriate as an initial action and contradicts professional obligations regarding confidentiality and responsible conduct.



A licensed professional working at a wastewater treatment plant owned and operated by XYZ company notices that their employer has been regularly ignoring elevated contaminant levels in effluent released into a waterway. These levels exceed Canadian regulation limits and may be hazardous to the environment and or the local population.
Which of the following courses of actions is most appropriate for the professional to take initially?

  1. Align themselves with XYZ management as their duty to their employer outweighs their duty to others.
  2. Resign in protest if they believe remaining with company XYZ may imply collusion in the illegal activities.
  3. Alert external regulatory agencies and the media that company XYZ is acting dishonestly and putting the environment and public at risk.
  4. Inform XYZ management of their reporting obligations and collaborate towards a viable solution that lowers contaminants to within regulation limits.

Answer(s): D

Explanation:

NPPE ethics materials consistently state that a professional's duty to protect the public and the environment supersedes loyalty to an employer. However, professionals are expected to follow a progressive and reasonable course of action. The initial response should be to notify management of the issue, clearly explain regulatory obligations, and attempt to resolve the situation internally.

Option D reflects this approach and is consistent with the duty to act responsibly, ethically, and constructively. NPPE references emphasize that professionals should use their expertise to correct unsafe practices before escalating the matter externally.

Option A is incorrect because duty to the employer never overrides duty to public safety. Option B may be appropriate if corrective efforts fail, but it is not the preferred initial action. Option C is premature and inconsistent with professional expectations regarding confidentiality and due process.
