Volenti non fit injuria

Volenti non fit iniuria (Latin for The Consenting not cheating ) is a legal principle, according to which a person who voluntarily and knowingly acts in such a way that from their action potential damage can occur, can not make any claims against other parties asserted. This insight is demanded that his actions may have consequences from responsible citizens. This is for example in sport at a boxer in the case who agrees to complete a fight and his opponent can not therefore sue afterwards for injuries caused by a blow; However, this shall not apply if a non- rule- compliant breakthrough was achieved.

This principle was written by the Roman jurist Ulpian.
