LEGAL PRINCIPLE: EVIDENCE LAW – Proof of Confession – Desirability of Corroboration
PRINCIPLE STATEMENT
It becomes desirable for the court to be very cautious in convicting the accused of the offense charged merely on his confession; hence the desirability to have, outside the confession, some material evidence, be it slight, of circumstances which make it probable that the confession is true.

EXPLANATION / SCOPE
While confessions alone can legally support convictions (see Principle 310), corroboration is highly desirable as a matter of prudent practice. Courts should exercise caution before convicting solely on confession and should seek “some material evidence, be it slight” corroborating the confession’s truth. This doesn’t mean full corroboration of every detail—even slight evidence making the confession more probably true suffices. Corroborative evidence might include: physical evidence consistent with confession (weapon, stolen property), testimony confirming confession details, or circumstances supporting confession credibility. This caution serves: protecting against false confessions (coerced, mistaken, or fabricated), ensuring confessions are reliable, and providing additional assurance of guilt. The standard is lower than full corroboration—”slight” evidence suffices if it makes confession truth more probable. However, this is desirability, not legal requirement—conviction on uncorroborated confession remains legally permissible if the court is satisfied beyond reasonable doubt. The principle counsels prudence while acknowledging legal sufficiency.
