La. Stat. tit. 33 § 2842
Whenever police juries or authorities of incorporated towns or cities have provided for the payment of a debt by levying a tax, and fail or refuse to cause the tax to be collected for the purpose of paying the debt and interest for which it was imposed, the district judge, on motion of the attorney of any of the creditors of the parish or incorporated town or city, after judgment has been rendered in their favor, shall issue his mandate directed to the tax collector of the parish or incorporated town or city in which the judgment has been obtained, to proceed forthwith to collect the taxes. The taxes shall be appropriated to the payment of the judgment and costs, the tax collector retaining the commissions allowed for the collection of taxes as compensation for his services.
