NOTICE AS TO FURTHER APPEAL
Pursuant to CPL 460.20, within 30 days after service upon you of a copy of the order of affirmance with notice of its entry, you have the right to apply for a certificate granting leave to take a further appeal to the Court of Appeals. Such application must be made either to the Chief Judge of the Court of Appeals by submitting it to the clerk of that court, as prescribed in CPL 460.20 (subdivisions 3b and 4), or to a justice of the Appellate Division of the Supreme Court in this department, as prescribed in section 670.7 of this Title and in CPL 460.20 (subdivisions 3a and 4). The denial of such application by the first judge or justice to whom it is presented is final; thereafter a new application may not be made to any other judge or justice.
