The term “Yellowstone injunction,” which derives from the Court of Appeals’ decision in National Stores, Inc. v. Yellowstone Shopping Center, 21 N.Y.2d 630 (1968), has evolved into a universally recognized brand name among experienced New York real estate litigators. These routinely granted injunctions stay the expiration of the cure period set forth in a landlord’s notice to cure, and enjoin the landlord’s termination of the lease, until the merits of the alleged default is determined by a court. When a tenant fails to obtain the injunction prior to the expiration of the noticed cure period, the lease terminates and, under Yellowstone, courts are powerless to revive it.
