Adjudged that the determination is confirmed, the petition is denied, and the proceeding is dismissed on the merits, without costs or disbursements.
"At an administrative expungement hearing, a report of child abuse or maltreatment must be established by a fair preponderance of the evidence" ( Matter of Blythe v Carrion, 63 AD3d 1059, 1059; see Matter of Lee TT. v Dowling, 87 NY2d 699, 703). "It is the function of the administrative agency, not the reviewing court, to weigh the evidence or assess the credibility of the witnesses" ( Matter of Bullock v State of N.Y. Dept. of Social Servs., 248 AD2d 380, 382).
"Our review . . . is limited to whether the determination was supported by substantial evidence in the record on the petitioners' application for expungement" ( Matter of Lynnann P. v Suffolk County Dept. of Social Servs., 28 AD3d 484, 484; see 300 Gramatan Ave. Assoc., v State Div. of Human Rights, 45 NY2d 176, 180; Matter of Bullock v State of N.Y. Dept. of Social Servs., 248 AD2d at 381). Substantial evidence "means such relevant proof as a reasonable mind may accept as adequate to support a conclusion or ultimate fact" ( 300 Gramatan Ave. Assoc., v State Div. of Human Rights, 45 NY2d at 180). Significantly, "[h]earsay is admissible in an administrative hearing and, if sufficiently relevant and probative, hearsay alone may constitute substantial evidence" ( Matter of Bullock v State of N.Y. Dept. of Social Servs., 248 AD2d at 382; see Matter of Ribya BB. v Wing, 243 AD2d 1013, 1014).
"Here, the . . . finding that a fair preponderance of the evidence established that the petitioner maltreated the subject child . . . is supported by substantial evidence" ( Matter of Blythe v Carrion, 63 AD3d at 1060; see Matter of Valentine v New York State Cent. Register of Child Abusers Maltreatment, 37 AD3d 249; Matter of Lynnann P. v Suffolk County Dept. of Social Servs., 28 AD3d 484; Matter of Sheomber v New York State Off. of Children Family Servs., 22 AD3d 761; Matter of Brown v Johnson, 294 AD2d 241; Matter of Solivan v Johnson, 9 AD3d 467; Matter of Bullock v State of N.Y. Dept. of Social Servs., 248 AD2d at 381-382; Matter of Ribya BB. v Wing, 243 AD2d at 1013). Accordingly, the determination must be confirmed, the petition denied, and the proceeding dismissed on the merits.
