Untimely ​Strict Products Liability Cause of Action Related Back to Timely Negligent Design Cause of Action—Motion to Amend Pleadings to Add Strict Products Liability Cause of Action Against Lessor of Heavy Equipment Should Have Been Granted

The Third Department determined plaintiff should have been allowed to amend the complaint to assert a strict products liability cause of action against the lessor of heavy equipment.  Plaintiff claimed to have slipped and fallen from a slippery surface on the heavy equipment.  The court noted the untimely strict products liability claim was nearly identical to the negligent design cause of action which had been timely alleged:

A commercial lessor may be held liable, even in the absence of fault, for injuries caused by a defective product that the lessor is in the business of leasing … . Leave to amend is to be freely granted “at any time,” so long as there is no prejudice or surprise to the other party (CPLR 3025 [b]…), “and the amendment is not plainly lacking in merit” … .

Although plaintiffs did not seek to amend the complaint until four years after the commencement of the action, [defendant] has not identified any actual prejudice or valid claim of surprise. The proposed amendment is not based on new facts and there is “almost no difference” between negligence and strict products liability claims based on defective design … . Given the functionally synonymous nature of the claims, we conclude that the complaint provided adequate notice of the necessary elements and the proposed amendment relates back to the timely interposition of the negligence claim (see CPLR 203 [f]…). Furthermore, the strict products liability claim cannot be said to be plainly lacking in merit as plaintiffs submitted an affidavit from a certified safety professional who opined that the slippery surface of the excavator was unreasonably dangerous, described why and explained how it could have been made safer … . Stokes v Komatsu Am Corp, 2014 NY Slip Op 02997, 3rd Dept 5-1-14
