As described by the U.S. Supreme Court in its unanimous decision concerning Ball v. United States 163 U.S. 662 (1896), one of its earliest cases dealing with double jeopardy, "the prohibition is not against being twice punished, but against being twice put in jeopardy; and the accused, whether convicted or acquitted, is equally put in jeopardy at the first trial."

The law of evidence is also concerned with the quantum (amount), quality, and type of proof needed to prevail in litigation. The rules vary depending upon whether the venue is a criminal court, civil court, or family court, and they vary by jurisdiction.
The party admission, in the law of evidence, is a type of statement that appears to be hearsay but is generally exempted (excluded) from the definition of hearsay because it was made by a party to the litigation adverse to the party introducing it into evidence.
