The motion court properly held that plaintiffs have standing to interpose their amended complaint, since their individual claims are separate and independent from a claim on behalf of the partnership (see,MK W. St. Co. v. Meridien Hotels, 184 A.D.2d 312, 313). The motion court also properly found that plaintiffs' amended pleadings were not time-barred, since they relate back to the original complaint, merely adding "additional factual detail" (see, State of New York v. St. James Nursing Home, 128 A.D.2d 694, 695).
