Since defendant landlord's failure to provide heat and hot water is not a proximate cause of the injuries sustained by plaintiff when she stumbled while carrying a pot of hot water, which she had heated on her stove, into the bathroom, the complaint must be dismissed pursuant to Martinez v. Lazaroff ( 48 N.Y.2d 819).
The rejection of the belated presentation of an entirely new theory of recovery as to disrepair of the bathroom floor was a proper exercise of the IAS Court's discretion since the considerable prejudice to defendant, which had completed its discovery and obtained summary judgment dismissing the complaint on the first theory, was properly treated as "[t]he operative factor considered" (Gonfiantini v. Zino, 184 A.D.2d 368, 369).
We have considered the plaintiff's remaining arguments, and find them to be without merit.
