Louisiana Revised Statutes Tit. 3, § 1430.9. Complaints

A. Any person who believes that he has suffered damages because he purchased materials which do not meet the standards set forth in R.S. 3:1430. 8 or because the amount of materials delivered was less than the net weight stated on the package or on the invoice may file a damage complaint with the commissioner.

B. All damage complaints shall be in writing, shall be on forms prescribed by the commissioner, shall be signed by the complainant, and shall be filed within fifteen days after the date of the sale or the date the deficiency was discovered, whichever is later. Failure to file a timely complaint shall not affect the right of the complainant to institute legal proceedings to recover the damages.

C. Each person who files a damage complaint shall allow the commissioner to inspect and sample the allegedly deficient material.
