The quasi-offense, referred to in article 1383 of the Civil Code, is an unintentional damaging act resulting from a simple fault of recklessness or negligence, however slight.
It is distinguished from the tort in civil matters which is the wrongful and damaging act committed voluntarily. It is covered by article 1382 of the Civil Code and entails the tort liability of its author. It matches the fault.
1382 and 1383
Despite the difference in the moral order, the civil code attaches to the offense and the quasi-offense the same consequences and obliges the party responsible to fully compensate for the damage he has caused.
