Probatio Diabolica/Devil’s Proof Law and Legal Definition

A legal requirement to achieve an impossible proof is called probatio diabolica. This is also called “devil's proof.” When a legal system requires an impossible proof, the only remedies available are reversing the burden of proof, or giving additional rights to the individual facing the probatio diabolica. When there is no proof to contradict a given statement, the statement can be considered true in some sense.
