Tamara A. Steckler, The Legal Aid Society, New York (John A. Newbery of counsel), for appellant.

Zachary W. Carter, Corporation Counsel, New York (Julie Steiner of counsel), for presentment agency.

Order of disposition, Family Court, New York County (Susan R. Larabee, J.), entered on or about April 11, 2014, which adjudicated appellant a juvenile delinquent upon a fact-finding determination that he committed an act that, if committed by an adult, would constitute the crime of assault in the third degree, and placed him on probation for a period of 12 months, unanimously affirmed, without costs.

The fact-finding determination was supported by legally sufficient evidence and was not against the weight of the evidence (see People v Danielson, 9 NY3d 342, 348-349 [2007]). There is no basis for disturbing the court's credibility determinations. The evidence established that appellant was the initial aggressor, and it disproved his justification defense beyond a reasonable doubt. Concur—Friedman, J.P., Andrias, Saxe, Gische and Kapnick, JJ.
