Thereafter, we granted the petitioner's request for certification to appeal, limited to the following issue: "Did the Appellate Court properly affirm the decision of the habeas court granting the motion of the petitioner's counsel to withdraw pursuant to Anders v. California, [supra, 386 U.S. 738]?" Riddick v. Commissioner of Correction, 292 Conn. 913, 973 A.2d 663 (2009). The petitioner now argues that the Appellate Court, utilizing an improper standard of review, improperly concluded that the habeas court and Levy followed the procedures required by Anders, and embodied in our rules of practice, for allowing appointed counsel to withdraw from habeas corpus proceedings.
