We granted certification of Oygard's appeal limited to the following issues: (1) "Did the Appellate Court properly conclude that an appellant's failure to file a zoning appeal within the thirty day time limit provided by General Statutes 8-7 deprives a zoning board of appeals of subject matter jurisdiction to hear the appeal?"; and (2) "If the answer to question (1) is yes, did the Appellate Court properly conclude that, under the circumstances of this case, Oygard's appeal was untimely?" Koepke v. Zoning Board of Appeals, 226 Conn. 913, 628 A.2d 985 (1993). We conclude that Oygard's appeal from the decision of the board was timely and, consequently, that there was no defect, subject matter or otherwise, in the board's authority to hear her appeal. Accordingly, we reverse the judgment of the Appellate Court.
