What duties does a lawyer owe to the adverse party?

A lawyer has a duty to uphold the integrity of the legal process, which includes respecting the rights of the adverse party. Specifically, this means that a lawyer must not obstruct another party's access to evidence. This obligation is rooted in ethical standards, which emphasize fairness and honesty in the legal profession.

Obstructing access to evidence would undermine the truth-finding process that courts rely upon to resolve disputes. This duty reflects a respect for the adversarial system, where both parties should have the opportunity to present their case fully and fairly. Promoting honest and equitable dealings not only maintains the trust in the legal system but also upholds a lawyer's professional responsibility to act with integrity.

The other choices fundamentally contradict the ethical principles guiding legal practice. While a lawyer must advocate for their client, this advocacy cannot come at the expense of fairness to opposing parties or the judicial process itself.
