How should a lawyer act upon discovering that evidence has been falsified?

When a lawyer discovers that evidence has been falsified, they face a significant ethical obligation to act in accordance with the law and the rules of professional conduct. Choosing to take reasonable remedial measures is the appropriate course of action to uphold integrity in the legal profession. This obligation may include notifying the court, taking steps to prevent the use of the falsified evidence, and examining whether withdrawal from the case is necessary to avoid further complicity in the misconduct.

The concept behind this answer emphasizes the lawyer's duty not only to their client but also to the justice system. Lawyers are required to ensure that they do not perpetuate false evidence and must act decisively to mitigate the situation. This aligns with ethical rules that dictate a lawyer’s responsibility to maintain honesty and integrity as part of their professional conduct.

Engaging in remedial actions demonstrates the lawyer's commitment to ethical standards and the legal process, which ultimately protects the integrity of the judicial system. Therefore, taking steps to rectify the situation, including possibly withdrawing from representation, is paramount to fulfill one's role as an officer of the court.
