PER CURIAM.
The parties concede, and we agree, that a finding of fact is necessary, i.e., a determination as to when the notice of final decision by the commission on human rights and opportunities was mailed. The resolution of that factual claim falls within the province of the trial court; we, as an appellate court, may not act as fact finders on claims not decided at the trial level. Connecticut National Bank v. Giacomi, 233 Conn. 304, 333, 659 A.2d 1166 (1995).
