Vollrausch (lit. 'intoxication') is a criminal provision (Section 323a of the German Criminal Code) which complements Actio libera in causa in German criminal law.
If a person who voluntarily and deliberately gets drunk but he or she did not intend to commit a crime before drinking but he or she satisfied the actus reus of another criminal offence, he or she might be criminally liable for the offence of 'Vollrausch'.
