Petitioner, a police officer, injured her ankle in a routine class exercise when she landed off balance. In denying petitioner's application for accidental disability retirement benefits, it was within respondent's purview to find that petitioner's injury was not the result of an unexpected event and was thus not an "accident" within the meaning of the statute. (Matter of Lichtenstein v Board of Trustees, 57 N.Y.2d 1010.)
Concur — Sullivan, J.P., Milonas, Rosenberger, Wallach and Smith, JJ.
