One of the widely used types of impossibility proof is proof by contradiction.In this type of proof, it is shown that if a proposition, such as a solution to a particular class of equations, is assumed to hold, then via deduction two mutually contradictory things can be shown to hold, such as a number being both even and odd or both negative and positive.
A negative claim is the opposite of an affirmative or positive claim. It asserts the non-existence or exclusion of something. [10] Logicians and philosophers of logic reject the notion that it is intrinsically impossible to prove negative claims.
A negative claim may or may not exist as a counterpoint to a previous claim.

Among the 93 overdose fatalities in Northern Kentucky in 2013, there were a good many who died shortly after leaving jail.
Probatio diabolica (Latin for "devil's proof" or "diabolical proof") is a legal requirement to achieve an impossible proof.Where a legal system would appear to require an impossible proof, the remedies are reversing the burden of proof, or giving additional rights to the individual facing the probatio diabolica.
