Opinion
PER CURIAM.The petitioner, Arnold Payne, appeals following the denial by the habeas court of his petition for certification to appeal from the denial of his petition for a writ of habeas corpus. He claims that the habeas court improperly determined that his trial counsel had provided effective assistance.1 In his petition, the petitioner claimed that his counsel failed to inform him fully of the direct consequences of his guilty plea. Spe*584cifically, the petitioner claimed that counsel failed to inform him that he would have to serve 85 percent of his sentence before he would be eligible for parole.2 The habeas court denied both the petition and the petitioner’s subsequent request for certification to appeal. We dismiss the appeal.
“In a habeas appeal, although this court cannot disturb the underlying facts found by the habeas court unless they are clearly erroneous, our review of whether the facts as found by the habeas court constituted a violation of the petitioner’s constitutional right to effective assistance of counsel is plenary.” White v. Commissioner of Correction, 58 Conn. App. 169, 170, 752 A.2d 1159 (2000), citing Johnson v. Commissioner of Correction, 36 Conn. App. 695, 700, 652 A.2d 1050, cert, denied, 233 Conn. 912, 659 A.2d 183 (1995). “Faced with a habeas court’s denial of a petition for certification to appeal, a petitioner can obtain appellate review of the dismissal of his petition for habeas corpus only by satisfying the two-pronged test enunciated by our Supreme Court in Simms v. Warden; 229 Conn. 178, 640 A.2d 601 (1994), and adopted in Simms v. Warden, 230 Conn. 608,612,646 A.2d 126 (1994). First, he must demonstrate that the denial of his petition for certification constituted an abuse of discretion. . . . Second, if the peti*585tioner can show an abuse of discretion, he must then prove that the decision of the habeas court should be reversed on its merits.” (Citation omitted; internal quotation marks omitted.) Petaway v. Commissioner of Correction, 49 Conn. App. 75, 77, 712 A.2d 992 (1998).
“To prove an abuse of discretion, the petitioner must demonstrate that the [resolution of the underlying claim involves issues that] are debatable among jurists of reason; that a court could resolve the issues [in a different manner]; or that the questions are adequate to deserve encouragement to proceed further.” (Internal quotation marks omitted.) Reddick v. Commissioner of Correction, 51 Conn. App. 474, 477, 722 A.2d 286 (1999). “For the petitioner to prevail on his claim of ineffective assistance of counsel, he must establish both that his counsel’s performance was deficient and that there is a reasonable probability that, but for the counsel’s mistakes, the result of the proceeding would have been different.” White v. Commissioner of Correction, supra, 58 Conn. App. 170, citing Strickland v. Washington, 466 U.S. 668, 694, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984); Bunkley v. Commissioner of Correction, 222 Conn. 444, 445, 610 A.2d 598 (1992).
In the present case, the habeas court based its dismissal of the petition for a writ of habeas corpus on a review of the petitioner’s claims and the evidence presented. The petitioner’s trial counsel testified that it was his standard practice to inform a defendant that he must serve 85 percent of his sentence before he would be eligible for parole, if in fact that were the case. The petitioner testified that his counsel mistakenly had informed him that he would be eligible for parole after serving only 50 percent of his sentence. In its memorandum of decision, the habeas court credited counsel’s testimony and rejected the petitioner’s testimony. Accordingly, the habeas court concluded that the petitioner failed to carry the burden of proof required to *586establish that his counsel had provided ineffective assistance.
“This court does not retry the case or evaluate the credibility of the witnesses. . . . Rather, we must defer to the [trier of fact’s] assessment of the credibility of the witnesses based on its firsthand observation of their conduct, demeanor and attitude. ... In a case that is tried to the court . . . the judge is the sole arbiter of the credibility of witnesses, and the weight to be given to their specific testimony.” (Citations omitted; internal quotation marks omitted.) Wieler v. Commissioner of Correction, 47 Conn. App. 59, 61, 702 A.2d 1195, cert, denied, 243 Conn. 957, 704 A.2d 806 (1997). Thus, the petitioner cannot successfully challenge the habeas court’s decision to credit counsel’s testimony and to reject his testimony.
Having reviewed the record and the briefs, we conclude that the petitioner has failed to make a substantial showing that he was denied a state or federal constitutional right. Furthermore, the petitioner has failed to sustain his burden of establishing that the denial of certification to appeal was a clear abuse of discretion or that an injustice has been done. See Simms v. Warden, supra, 230 Conn. 612; Simms v. Warden, supra, 229 Conn. 189. Therefore, we conclude that the habeas court had before it sufficient evidence to find as it did and that it did not abuse its discretion in denying the petition for certification to appeal.
The appeal is dismissed.
