La. Stat. tit. 3 § 739
The director shall continually review and examine the recorded brands and marks to determine if there are conflicting brands or marks recorded with the commission. When the director determines that a conflict exists, the director shall notify both persons who have recorded the brand or mark and shall expunge the more recent recordation. The person whose recordation is expunged shall be notified by registered mail that his recordation has been expunged and that further use of this brand or mark is illegal. Persons whose recordation has been expunged may appeal the decision of the director to the commission. The provisions of this Section shall not affect the ownership of any animals which were branded or marked after the brand or mark was recorded and before the recordation was expunged.
