Which scenario would likely violate the principle of candor to the tribunal?

Withholding favorable evidence from the tribunal constitutes a violation of the principle of candor to the tribunal because attorneys have an obligation to be honest and forthright in their dealings with the court. The duty of candor requires that lawyers must not only refrain from making false statements but also actively disclose information that could be relevant and beneficial to the court, particularly when it pertains to evidence that could affect the outcome of the case.

In legal practice, this principle helps ensure that the court is able to make informed decisions based on all pertinent facts, which is essential for the integrity of the judicial process. Withholding evidence that could favor the opposing party or that the court needs for a complete understanding undermines this process and can lead to sanctions against the lawyer involved.

In contrast, presenting a complete case, providing truthful testimony, and disclosing applicable laws align with the duties lawyers owe to the court. Each of these actions supports transparency and integrity in legal proceedings, thereby upholding the principle of candor.
