Article 20. Fault
(1) Unless the law provides otherwise, a person is liable only for loss caused by its act with fault either in the form of intent or negligence.
(2) An act is committed with intent if the person who did it knew of the damaging nature of its action or inaction, has foreseen its damaging consequences, wanted or willingly admitted the occurrence of those consequences.
(3) An act is committed with negligence if the person who did it either knew of the damaging nature of its action or inaction, has foreseen its damaging consequences, but negligently thought they can be avoided, or was not aware of the damaging nature of its action or inaction, has not foreseen its damaging consequences, but should and could have foreseen them.
(4) There is gross negligence if a person is guilty of a profound failure to take such care as is self-evidently required in the circumstances.
(5) Where the law requires an act to be committed with negligence for legal consequences to occur, then the requirement is also met when the act is committed with intent.
