A person is aggrieved within the meaning of CPLR 5511 when he asks for relief but relief is denied in whole or in part, or when someone opposes the relief asked against him, and the relief is granted in whole or in part. Here, since the defendant is not aggrieved by the order appealed from, the appeal must be dismissed.
