Furthermore, it is also the law that the confessional statement of an accused person alone is sufficient to ground a conviction. A confession alone, properly proved, is enough to ground a conviction, even without corroboration. Thus, an uncorroborated confessional statement of an accused person can be acted upon, without more. Nonetheless, it is advisable to look for some evidence outside the confessional statement which makes it probable that the confession is true.
