State v. Golding
In State v. Golding, 213 Conn. 233, 239-40, 567 A.2d 823 (1989) the Court held that a defendant can prevail on a claim of constitutional error not preserved at trial only if all of the following conditions are met:
(1) the record is adequate to review the alleged claim of error;
(2) the claim is of constitutional magnitude alleging the violation of a fundamental right;
(3) the alleged constitutional violation clearly exists and clearly deprived the defendant of a fair trial;
(4) if subject to harmless error analysis, the state has failed to demonstrate harmlessness of the alleged constitutional violation beyond a reasonable doubt.
