DR 7-101 Representing a Client Zealously.

A. A lawyer shall not intentionally:

    1. Fail to seek the lawful objectives of his client through reasonably available means permitted by law and the Disciplinary Rules, except as provided by DR 7-101(B). A lawyer does not violate this Disciplinary Rule, however, by acceding to reasonable requests of opposing counsel which do not prejudice the rights of his client, by being punctual in fulfilling all professional commitments, by avoiding offensive tactics, or by treating with courtesy and consideration all persons involved in the legal process.
    2. Fail to carry out a contract of employment entered into with a client for professional services, but he may withdraw as permitted under DR 2-110,
      DR 5-102, and DR 5-105.
    3. Prejudice or damage his client during the course of the professional relationship, except as required under DR 7-102(B).

B. In his representation of a client, a lawyer, may:

    1. Where permissible, exercise his professional judgment to waive or fail to assert a right or position of his client.
    2. Refuse to aid or participate in conduct that he believes to be unlawful, even though there is some support for an argument that the conduct is legal.
