Cap. 16 Art. 1878Liability of mandatary for interest on sums applied to his own use, etc.

A mandatary owes interest on the sums which, without the authority of the mandator, he has applied to his own use, from the day on which he has made such use, and on any other sum in which he shall remain debtor, from the day on which he is put in default, saving, in both the aforesaid cases, the usages of trade.
