Issues of fact exist, including whether plaintiff's injuries were caused by his alleged fall from an unsteady ladder or whether they resulted from his repetitive use of a shotgun nailing machine. We need not reach the question whether various reports, unsworn but arguably containing admissions against plaintiff's interest, constituted evidence in admissible form ( cf., Ferrara v. Poranski, 88 A.D.2d 904; Schanberg v. State of New York, 30 A.D.2d 712), because "evidence, otherwise excludable at trial, may be considered to deny a motion for summary judgment provided that this evidence does not form the sole basis for the court's determination" ( Wertheimer v. New York Prop. Ins. Underwriting Assn., 85 A.D.2d 540, 541).
