CPLR 1003 requires leave of court or a stipulation by all parties to add parties, at least where, as here, parties have previously been added. CPLR 3025(a)-(b) similarly requires leave of court or a stipulation by all parties to amend a complaint, at least when done so late in the case. Because this procedure was not followed, the amended complaint must be dismissed as against the newly joined defendant.
