Answer:
True
Explanation:
If a defendant does not plead ʺnot guilty by reasons of insanity,ʺ he or she may be presumed to be sane at the time the crime was committed. This implies that the defendant was in the right state of mind when the crime was committed. On the contrary, if the defendant pleads not guilty by reasons of insanity, it means that he or she was not in a right state of mind when the crime was committed, however the onus lies with prosecution to disprove his or her claim of insanity.
