RS 14:68

Unauthorized use of a movable

A. Unauthorized use of a movable is the intentional taking or use of a movable which belongs to another, either without the other’s consent, or by means of fraudulent conduct, practices, or representations, but without any intention to deprive the other of the movable permanently. The fact that the movable so taken or used may be classified as an immovable, according to the law pertaining to civil matters, is immaterial.

B. Whoever commits the crime of unauthorized use of a movable having a value of one thousand dollars or less shall be fined not more than five hundred dollars, or imprisoned for not more than six months, or both. Whoever commits the crime of unauthorized use of a movable having a value in excess of one thousand dollars shall be fined not more than five thousand dollars, or imprisoned with or without hard labor for not more than five years, or both.
