We granted the state's petition for certification to appeal limited to the following issue: "Did the Appellate Court properly conclude that the defendant had not validly waived his right to a jury trial?" State v. Gore, 280 Conn. 937, 910 A.2d 218 (2006). Because we affirm the judgment of the Appellate Court on the ground that defense counsel's waiver of the defendant's right to a jury trial on the defendant's behalf was invalid, we need not address the defendant's alternate ground for affirmance in which he claims that the trial court improperly permitted the state to introduce into evidence a state trooper's testimony concerning inculpatory statements allegedly made by the defendant during custodial interrogation.
