State v. Veal
In State v. Veal, 201 Conn. 368, 517 A.2d 615 (1986), the Court stated:
"We have never held . . . that a trial court has a due process obligation to examine the evidence sua sponte to see whether it supports the existence of the mitigating circumstances contemplated by the defense of extreme emotional disturbance. On the contrary, we have previously concluded that a trial court has not deprived a defendant of a fundamental constitutional right and a fair trial by giving a jury instruction that, in the absence of a timely request or exception, omits any reference to an affirmative defense such as extreme emotional disturbance." Id., 373.
