PER CURIAM.
After a review of the record and briefs, and after hearing from the parties at oral argument, we conclude that the petitioner has failed to make a substantial showing that he has been denied a state or federal constitutional right and, further, has failed to sustain his burden of persuasion that the denial of certification to appeal was a clear abuse of discretion or that an injustice has been done. See Simms v. Warden, 230 Conn. 608, 612, 646 A.2d 126 (1994); Simms v. Warden, 229 Conn. 178, 179, 640 A.2d 601 (1994); Walker v. Commissioner of Correction, 38 Conn. App. 99, 99-100, 659 A.2d 195 (1995); see also Lozada v. Deeds, 498 U.S. 430, 431-32, 111 S.Ct. 860, 112 L.Ed.2d 956 (1991).
