We have the best witness in an accused who confesses the charge.

Explanation

A voluntary confession by the accused is the strongest evidence of guilt — no testimony from any other witness can surpass the defendant's own admission.

Where this applies

• The defendant confessed to the crime — isn't that the strongest possible evidence.
• Someone admitted guilt voluntarily and now wants to retract it.
• The accused made a full confession on the record but the case is still being contested.
