application be denied. The board accepted this recommendation, and on November 29,1982 the Commissioner of Education executed an order denying the application for reconsideration. The instant CPLR article 78 proceeding followed. Petitioner contends that the commissioner’s determination was arbitrary and capricious on three grounds: (1) that her original counsel incorrectly told her that a unanimous, rather than a four-fifths, vote of the hearing panel was required for its determination (Education Law, § 6510, subd 3, par d); (2) that her original counsel misinformed her as to the effect on her employment of a one-month suspension and, therefore, she had not expected to lose her job; and (3) that she is innocent of the underlying charges. An application for reconsideration of a determination of the Board of Regents in a disciplinary proceeding will not be granted unless there is “a showing that the determination was rendered under a misunderstanding as to the facts, or was based on an error of law, or that there is new and material evidence which was not previously available, or that the circumstances have occurred subsequent to the original determination which warrant a reconsideration of the measure of discipline” (8 NYCRR 3.3 [f]). In the instant case, no mutual mistake of the law or the facts occurred (see
Brauer v Central Trust Co., 77 AD2d 239 ,243, mot'for lv to app den 52 NY2d 703 ). The board clearly did not base its determination on any error of law; the mistake as to the number of hearing panel members who must agree on a determination was solely on petitioner’s part. We cannot say that it was irrational for the commissioner to decide that a licensed professional’s agreement to a consent order on the basis of erroneous information from her attorney is not the kind of error of law that the regulation contemplates. Similarly, petitioner’s misunderstanding as to the effect of the consent order on her employment was also a unilateral mistake on her part. Petitioner characterizes this misunderstanding as “circumstances [which] have occurred subsequent to the original determination”. Again, however, it was not irrational for the commissioner to decide that, in order to warrant a reconsideration, new circumstances must be pertinent to the determination of the petitioner’s guilt or innocence and not, as here, only to the sanction imposed. As for petitioner’s allegation that she is innocent of the underlying charges, this claim does not satisfy any of the four requirements for reconsideration set forth in 8 NYCRR 3.3 (f). Therefore, the commissioner’s denial of petitioner’s application for reconsideration had a rational basis and was not arbitrary or capricious. Petitioner also alleges that the denial of her application should be annulled because it does not contain any findings. Since the grant or denial of an application for reconsideration is discretionary, our review here is limited to whether the commissioner abused his discretion
{Matter ofKlabin [Cather-wood\, 30 AD2d 1005 ;
Matter of Crowley [Corsi], 275 App Div 977 ). Respondents’ opposing papers justify dismissal of the application for reconsideration because petitioner’s arguments did not meet any of the four requirements for reconsideration under 8 NYCRR 3.3 (f); specifically, that any misunderstandings of law or facts were entirely on the part of petitioner; that losing her job was not a circumstance relating to, and tending to exonerate her from, the initial charge of unprofessional conduct; and that her claim of innocence, in addition to being irrelevant to the regulation, was contradicted by admissions which petitioner had made to investigators in the case. An administrative determination in the exercise of discretion is sustainable if, as here, a rational basis for that determination is demonstrated in the agency’s opposing papers
{Matter of McPartland v McCoy, 35 AD2d 641 , 642, revd on other grounds
32 NY2d 479 ). We have examined petitioner’s other points and find them to be without merit. Accordingly, the determination should be confirmed, and the petition dismissed. Determination confirmed, and petition dismissed, without costs. Kane, J. P., Main, Mikoll, Yesawich, Jr., and Levine, JJ., concur.
