—[*1] Thomas S. Fleishell & Associates, P.C., New York (Susan C. Stanley of counsel), for appellant.

Gary R. Connor, New York (Aida P. Reyes of counsel), for Division of Housing and Community Renewal, respondent.

Belkin Burden Wenig & Goldman, LLP, New York (Brian Clark Haberly and Magda L. Cruz of counsel), for Colombus Limited Partnership and Rockrose Development Corp., respondents.

Order and judgment (one paper), Supreme Court, New York County (Paul G. Feinman, J.), entered July 5, 2007, denying the petition and dismissing the proceeding brought pursuant to CPLR article 78 to annul the determination of respondent New York State Division of Housing and Community Renewal (DHCR), dated July 3, 2006, which affirmed an order of the Rent Administrator deregulating petitioner's apartment based on his alleged default in answering a high income rent deregulation petition, unanimously affirmed, without costs.

Since petitioner failed to submit any objective proof that he mailed his answer to the landlord's deregulation petition, DHCR's determination that petitioner defaulted was neither arbitrary and capricious nor contrary to law (see Matter of Szaro v New York State Div. of Hous. & Community Renewal, 13 AD3d 93 [2004]). Petitioner's due process claim is unavailing. To the extent, if any, we may take cognizance of petitioner's belated suggestion (first raised in his reply brief on this appeal) that the matter be remanded to DHCR to consider whether his default is excusable by reason of his alleged diminished capacity, we find that petitioner has failed to raise any substantial issue as to his capacity at the time of his default. Concur—Mazzarelli, J.P., Friedman, Nardelli, Buckley and Freedman, JJ.

Reargument granted and, upon reargument, the decision and order of this Court entered on December 16, 2008 (57 AD3d 312 [2008]) recalled and vacated and a new decision and order substituted therefor. Leave to appeal to the Court of Appeals denied. [See 2007 NY Slip Op 31864(U).]
