Art sued Deb for breach of contract, for failing to provide habitable property, after Art moved into an apartment leased through an agent of Deb’s which he found was infested with bugs.  Deb filed an answer to Art’s complaint, denying all allegations except for the allegation that Deb owned the property, which Deb admitted.  In fact, Deb had sold the property to Don just after Art signed the lease, and before Art moved into the property.  About one month later, Deb filed a motion for leave to amend her answer to the complaint to allege that she did not own the property at the time Art moved into the apartment.  The statute of limitations has lapsed, so that it is too late for Art to sue Don.  How should the court rule on the motion?
