N.Y. Comp. Codes R. & Regs. tit. 22 § 700.4 : JUDICIARY — Courts — Supreme Court — Second Judicial Department — Appellate Division — Special Rules — Court Decorum — Obligations of the attorney

(a) Attorneys are both officers of the court and advocates. It is their professional obligation to conduct each case courageously, vigorously, and with all the skill and knowledge they possess. It is also their obligation to uphold the honor and maintain the dignity of the profession. They must avoid disorder or disruption in the courtroom and must maintain a respectful attitude toward the court. In all respects attorneys are bound, in court and out, by the provisions of the Rules of Professional Conduct.
(b) Attorneys shall use their best efforts to dissuade their client and witnesses from causing disorder or disruption in the courtroom.
(c) Attorneys shall not engage in any examination which is intended merely to harass, annoy or humiliate the witness.
(d) No attorney shall argue in support of or against an objection without permission from the court; nor shall any attorney argue with respect to a ruling of the court on any objection without such permission. However, an attorney may make a concise statement of the particular grounds for an objection or exception, not otherwise apparent, where it is necessary to do so in order to call the court's attention thereto, or to preserve an issue for appellate review. If an attorney believes in good faith that the court has wrongly made an adverse ruling, he or she may respectfully request reconsideration thereof.
(e) Attorneys have neither the right nor duty to execute any directive of a client which is not consistent with the Rules of Professional Conduct set forth in Part 1200 of this Title. Nor may attorneys advise another to do any act or to engage in any conduct in any manner contrary to these rules.
(f) Once a client has employed an attorney who has entered an appearance, the attorney shall not withdraw or abandon the case without:
(1) justifiable cause;
(2) reasonable notice to the client; and
(3) permission of the court.
(g) Attorneys are not relieved of these obligations by what they may regard as a deficiency in the conduct or ruling of a judge or in the system of justice; nor are they relieved of these obligations by what they believe to be the moral, political, social, or ideological merits of the cause of any client.
