§ 1807-A. Proceedings on default and review of judgments. (a) A\nclaimant commencing an action upon a commercial claim under this article\nshall be deemed to have waived all right to appeal, except that either\nparty may appeal on the sole grounds that substantial justice has not\nbeen done between the parties according to the rules and principles of\nsubstantive law.\n (b) The clerk shall mail notice of the default judgment by first class\nmail, both to the claimant and to the party complained against. Such\nnotice shall inform the defaulting party, in language promulgated by the\nstate office of court administration, of such party's legal obligation\nto pay; that failure to pay may result in garnishments, repossessions,\nseizures and similar actions; and that if there was a reasonable excuse\nfor the default, the defaulting party may apply to have the default\nvacated by submitting a written request to the court.\n (c) Proceedings on default under this article are to be governed by,\nbut are not limited to, section five thousand fifteen of the civil\npractice law and rules.\n
