True or False: A lawyer has a duty not to promote frivolous or vexatious claims.

The assertion is true because lawyers are bound by ethical rules to avoid promoting claims that lack a legal basis or are intended to harass or burden an opposing party. This duty is part of a lawyer's responsibility to the court and the legal system as a whole. Promoting frivolous or vexatious claims undermines the integrity of the judicial process and may lead to sanctions, including disciplinary action against the lawyer.

The ethical obligation to refrain from such conduct is rooted in principles that prioritize justice and fairness in legal proceedings. Lawyers must evaluate the merits of their cases and ensure that any claims or defenses presented are grounded in law and facts that can be substantiated. This ensures that the legal process is used properly and that clients’ rights are protected while simultaneously respecting the rights of others and the legal system.
