Only an aggrieved party or a person substituted for him may appeal from an appealable judgment, order, or final order, pursuant to CPLR 5511. A person is aggrieved when he asks for relief but that relief is denied in whole or in part, or when someone asks for relief against him, which the person opposes, and the relief is granted in whole or in part.
