La. Sup. Ct. R. IV, § 11

A brief of an amicus curiae shall be filed only by leave of court granted upon

motion and notice to the parties. The amicus curiae brief shall be conditionally

filed with the motion for leave. A motion for leave to file an amicus curiae brief

must include consideration of and satisfaction of at least one of the following

criteria:

A. amicus has an interest in some other case involving a similar question;

B. there are matters of fact or law that might otherwise escape the Court's

attention; or

C. the amicus has substantial, legitimate interests that will likely be affected by the

outcome of the case and which interests will not be adequately protected by

those already party to the case.

A motion for leave to file an amicus curiae brief, and the conditionally filed amicus

curiae brief, shall be filed within the time allowed for the filing of a brief by the

party whose position as to affirmance or reversal the amicus brief will support. The

motion for leave to file an amicus brief shall not exceed five (5) pages in length

and the amicus curiae brief shall not exceed fifteen (15) pages in length.

No reply brief of an amicus curiae and no brief of an amicus curiae in support of a

petition for rehearing shall be accepted.

The Clerk of Court shall be entitled to receive the filing fee set forth in Rule II for

the filing of any motion for leave to file an amicus curiae brief in this Court. This

fee shall not be assessed by the Clerk when the motion for leave is presented by the

Attorney General for the State of Louisiana.
