dissenting.
A disciplinary proceeding was initiated before the Georgia State Board of Pharmacy, an agency of the State of Georgia, against Lov-vorn, a registered pharmacist, and his pharmacy. Thomas B. Murphy filed with the board an appearance as counsel for Loworn. The Attorney General, on behalf of the board, submitted a “Motion to Disqualify Thomas B. Murphy as Attorney for Defendant.”
A hearing officer denied the motion. That ruling was affirmed by the superior court, and we granted discretionary appeal.
It is agreed that at all times material Speaker Murphy was a member of the Georgia House of Representatives, and its Speaker. He filed an affidavit, which is undisputed, stating that he has refused compensation from Loworn and “therefore, stand[s] no chance of having any personal financial gain,” and that he is representing Lov-vorn “without any hope of financial gain.”
In affirming the hearing officer, the superior court observed:
“[T]his Court concludes that the decision of the Georgia Supreme Court in Georgia Department of Human Resources v. Sistrunk, 249 Ga. 543 [291 SE2d 524] (1982), does not prohibit a lawyer/ legislator from representing a client in an adversarial proceeding before an administrative agency when no fee is charged for services rendered.”
1. Our opinion in Sistrunk, supra, was in two parts. The first was a rejection of the Attorney General’s contention that a legislator owed “complete loyalty” and a “fiduciary duty” to the Department of Human Resources. The Attorney General also pointed out several provisions of the Code of Professional Responsibility, alleging impropriety or conflict of interest, to which the legislator involved in that case asserted “that nothing suggested by the Department is contrary to the Code of Professional Responsibility.” We held there as follows: “As to Hill’s last contention, we agree. There is no dual representation in these circumstances, for the plain reason that a member of the General Assembly represents not the government of our State, nor any of its branches, departments, or agencies, but the electorate which is his constituency.” 249 Ga. at 543. (It is important to note that a review of the briefs filed by the parties in Sistrunk reveals no reference to EC 7-9, infra, and hence its effect was not among those propositions “suggested by the Department” as “contrary to the Code of Professional Responsibility.”)
So ruling, we went on to state: “The issue in this case is, then, the meaning of the constitutional provision declaring that ‘[pjublic *262officers are the trustees and servants of the people, and at all times amenable to them.’ ” 249 Ga. at 544.
The answer to that inquiry, reiterated in Stephenson v. Benton, 250 Ga. 726, 728 (300 SE2d 803) (1983), was stated, 249 Ga. at 547, as follows:
“All public officers, within whatever branch and at whatever level of our government, and whatever be their private vocations, are trustees of the people, and do accordingly labor under every disability and prohibition imposed by law upon trustees relative to the making of personal financial gain from the discharge of their trusts.
“May one trustee of the people, as attorney and for his own financial gain, initiate or defend a lawsuit on behalf of another which seeks to defeat the official public actions of another trustee of the people?
“May one trustee of the people, as attorney and for his own financial gain, negotiate on behalf of another for a favorable official dispensation at the hands of another trustee of the people?
“Specifically concerning legislators, may one trustee of the people — in whose office are vested the powers of enhancement, diminution, and destruction of the office of another trustee of the people — as attorney and for his own financial gain act in a manner to hinder or frustrate the discharge by such other trustee of the duties of their common trust?
“No.”
2. Sistrunk spoke in terms of “financial gain” because that was the circumstance then before us. In this case, however, Speaker Murphy is acting “without any hope of financial gain.” Hence, the express holding of Sistrunk, if strictly construed, does not fit the specific factual elements of this case.
“We rather view this case as one which calls for the exercise of this court’s authority to regulate the practice of law. This court has the authority and in fact the duty to regulate the law practice and in the past two decades we have been diligent in our exercise of this duty. [Cits.] The diligence of this court has been directed toward the assurance that the law practice will be a professional service and not simply a commercial enterprise. The primary distinction is that a profession is a calling which demands adherence to the public interest as the foremost obligation of the practitioner.” First Bank &c. Co. v. Zagoria, 250 Ga. 844, 845 (302 SE2d 674) (1983).
3. At the time Speaker Murphy undertook to represent Loworn as an attorney in an adversarial proceeding with an agency of the state, he was a member of the Georgia House of Representatives. As member, he had subscribed to the oath required by Art. Ill, Sec. IV, Par. II of the Constitution of Georgia of 1983 and by OCGA § 28-1-4, which is as follows: “I do hereby solemnly swear or affirm that I will *263support the Constitution of this state and of the United States and, on all questions and measures which may come before me, I will so conduct myself, as will, in my judgment, be most conducive to the interests and prosperity of this state.” Speaker Murphy and all other members of the General Assembly labor under this solemn obligation.
The issue of this case, as distinguished from the issue in Sis-trunk, is this: Can a lawyer (who, because he is a member of the General Assembly is encumbered by this oath) fulfill his duty — as a lawyer — to his client in an adversarial proceeding with a state agency?
4. Ethical Consideration 7-9, as republished by this court on November 4, 1983 (252 Ga. 571, 619) provides, among other things, that “a lawyer should always act in a manner consistent with the best interests of his client.” It is a proud hallmark of the legal profession that an attorney owes undivided loyalty to his client — undiluted by conflicting or contrariant obligations, and undiminished by interests of himself or of others.
“Thus we conclude that the relation of attorney and client is of such an important nature that the courts may not allow an attorney to act in any capacity or assume any duty inconsistent with the office of attorney, or the duty owing to the client; public policy also demands that an attorney shall not act in any other capacity where that duty would be incompatible with the general duty as an attorney.” Young v. Champion, 142 Ga. App. 687, 690 (236 SE2d 783) (1977).
5. Can a lawyer who is already bound by an oath to conduct himself on all questions and measures before him as will in his judgment be “most conducive to the interests and prosperity of this state” (OCGA § 28-1-4) — at one and the same time — “always act in a manner consistent with the best interests of his client” (EC 7-9), when that client and an agency of the state are locked in adversarial conflict?
The answer, obviously, must be “No.”
6. We need not determine whether Speaker Murphy, as Representative, is acting consistently with his duties as a public officer and servant and trustee of the people. Instead, in the exercise of our general supervisory powers over the Bar and the practice of law, we should hold that as attorney, he must be disqualified from representing Loworn before the Georgia State Board of Pharmacy. This is so because his oath as public officer lays upon him a heavy impediment which severely diminishes his ability, as attorney in this case “always [to] act in a manner consistent with the best interests of his client.”1
