Louisiana Revised Statutes Tit. 51, § 150. Discovery; contempt

If any witness is properly served with notice to appear and testify, and fails to obey the notice, or refuses to testify or produce books or papers, the attorney general or district attorney may file a statement with the judge, setting out the facts, and the judge may issue a citation to the parties causing them to appear and show cause why he should not be punished for contempt. In these contempt proceedings, the person may be fined not more than two thousand dollars or imprisoned not more than six months, or both.
