A plaintiff moving for summary judgment on the issue of liability must establish, prima facie, that the defendant breached a duty owed to the plaintiff, and that the defendant's negligence was a proximate cause of the alleged injuries. While the plaintiff need not establish the absence of comparative fault, the issue of a plaintiff's comparative negligence may be decided on a summary judgment motion where, as here, the plaintiff moves for summary judgment dismissing the defendant's affirmative defense of comparative negligence.
