This is an appeal from an order of the Superior Court sustaining the respondent’s demurrer to a petition for writ of mandamus. The petitioner is a citizen of the Commonwealth and the brother and coguardian of Edabeth Berman Katz, the victim of alleged malpractice by two physicians, an anesthesiologist and an obstetrician, licensed to practice medicine in the Commonwealth. See G. L. c. 112, § 2.
The petition seeks to compel the board to cite the physicians for a hearing on the possible suspension or revocation of their licenses to practice medicine. A demurrer was sustained which asserted that the petition is insufficient in law, the act sought is discretionary, the petition shows that *359the board has exercised its discretion, and the petitioner lacks standing.
The petition alleges that on November 21, 1964, Mrs. Katz suffered severe brain damage during childbirth, resulting in the loss of all upper brain functions. This resulted from aspiration of vomit into her windpipe and lungs and consequent deprivation of oxygen for from twelve to fifteen minutes, while Mrs. Katz was under general anesthesia, and in the care of the physicians. The petition alleges various acts of alleged malpractice and that the obstetrician falsified medical records so that it would appear that accepted medical practice had been followed. It alleges that on October 28, 1966, the guardians of Mrs. Katz recovered a jury verdict against the physicians of $330,000. An exhibit shows a newspaper account that refers to an additional $53,000 awarded for medical expenses. The case was settled under an agreement for judgment for neither party.
Beginning March 20, 1967, Frank E. Berman, Esquire, father of Mrs. Katz, in a series of letters, made a detailed presentation of the complaint to the board including the transcript of the malpractice trial. He said that he would produce witnesses at a board hearing. On June 20, 1967, the secretary of the board wrote Mr. Berman that it would conduct its own investigation. On September 26, 1967, the secretary of the board informed Mr. Berman that the board at a meeting on September 21, 1967, as a result of its investigation of the matter, had voted not to cite the physicians for a hearing.
The statute (G. L. c. 112, §§ 61 and 621) authorizes the board after notice and hearing to suspend or revoke licenses *360for specified cause, including malpractice and gross misconduct. There can be no doubt that such a proceeding would be an adjudicatory proceeding, G. L. c. 30A, § 1 (1), and, if the petitioner were allowed to intervene, he would be a party, c. 30A, § 1 (3).
The statute, however, does not give the petitioner a legal right in respect of the decision to initiate or not initiate an adjudicatory proceeding under §§61 and 62. There is no suggestion of this in c. 112 and, of course, no such suggestion in c. 30A. The petitioner acts as a member of the public in calling a matter of public concern and the board’s concern to the attention of the board. He has no right to participate in the board’s decision whether to act under § 61. That the board has rules for adjudicatory proceedings is beside the point.
The petitioner asserts a right as a member of the public to present a public right. Assuming that he has the right to compel the board to consider whether to act in respect of a matter of public concern within its jurisdiction, brought to its attention (Brewster v. Sherman, 195 Mass. 222, 224, Parrotta v. Hederson, 315 Mass. 416, 418), the petition shows that the board has considered the matter. The petitioner in effect asserts the further right to bring a public action to review the board’s preliminary discretionary decision not to act. There is no such right under our statutes or law. Relief under G. L. c. 30A, § 14, is available only as to adjudicatory proceedings and then only as to an aggrieved party. Compare G. L. c. 44, § 59, authorizing a taxpayer’s suit to enforce that chapter. Mandamus does not lie to compel an administrative agency to perform a discretionary act. Lehigh v. Commissioner of Pub. Health & Charities of Lawrence, 310 Mass. 343, 344. Where a legal right is affected, abuse of discretion may amount to error of law. Here, however, there is no legal right. This court is not empowered to direct an administrative board how to perform its public duties. See Associated Indus. v. Ickes, 134 F. 2d 694, 700-705 (2d Cir.), vacated as moot, 320 ü. S. 707.
*361If there is to be means whereby, in a flagrant case, a citizen who knows the facts can require a review of an administrative board’s decision not to act under its statutory power, that is a matter for the Legislature. See, as to the possible desirability of such relief, Jaffe, Judicial Control of Administrative Action, c. 12, pp. 475-486. We do not know what the board’s investigation revealed; on the allegations of the petition, we understand the petitioner’s concern. There is, however, no basis for the court to assume jurisdiction.
Order sustaining demurrer affirmed.
