Before entering into a guilty or no contest plea, the trial court record must show on its face that the defendant was made aware of and waives his or her Boykin-Tahl rights. Boykin-Tahl righs i.e, the consitutional rights required in Boykin v. Alabama. The plea is valid if the record affirmatively shows that it is voluntary and intelligent in the totality of the circmstances.
A not guilty of reason of insanity plea must be entered personally by the defendant and not through his attorney. A defendant who fails to join an Not Guilty By Reason of Insanity plea with a not guilty plea admits the offense charged. The defendant must be informed by the Court of his or her Boykin-Tahl rights. If however the defendant pleads both not guilty by reason of insanity and not guilty, the court does not need to advise the defendant of his or her Boykin-Tahl rights.
