A more thorough explanation:

Definition: Plena probatio is a Latin term that means "full proof" or "complete evidence." It refers to the highest standard of proof required in a legal case, where the evidence presented is sufficient to establish the truth of a fact beyond a reasonable doubt.

For example, in a criminal trial, the prosecution must present plena probatio to convince the jury that the defendant is guilty of the crime charged. This means that the evidence must be strong enough to leave no reasonable doubt in the minds of the jurors about the defendant's guilt.

Another example is in a civil case, where the plaintiff must present plena probatio to prove their case. This means that the evidence must be sufficient to establish the plaintiff's claim by a preponderance of the evidence, which means that it is more likely than not that the plaintiff's claim is true.

The examples illustrate how plena probatio is the highest standard of proof required in legal cases, where the evidence presented must be strong enough to establish the truth of a fact beyond a reasonable doubt or by a preponderance of the evidence.
