Such certificate may be issued by the following judges in the\nindicated situations:\n (a) Where the appeal sought is from an order of the appellate\ndivision, the certificate may be issued by (i) a judge of the court of\nappeals or (ii) a justice of the appellate division of the department\nwhich entered the order sought to be appealed.\n (b) Where the appeal sought is from an order of an intermediate\nappellate court other than the appellate division, the certificate may\nbe issued only by a judge of the court of appeals.\n 3.
