Article 37 Guilty plea
If an accused pleads guilty to a charge, the judge advocate shall, if it appears necessary to him and before the court accepts the plea, satisfy himself that the accused understands—
the nature of the charge;
the general effect of the plea; and
the difference in procedure following pleas of guilty and not guilty.
The court shall not accept a plea of guilty if—
the court is not satisfied that the accused understands the nature of the charge or the effect of his plea;
the judge advocate, having regard to all the circumstances, considers that the court should not accept the plea;
the accused is liable, if convicted, to a sentence of death.
Where—
a plea of guilty is not accepted by the court; or
the accused does not plead to the charge or does not plead to it intelligibly,
the court shall enter a plea of not guilty.
