La. R.S. 47:1547 — Procedure to compel witnesses to attend and to testify at hearing

If a person subpoenaed to attend any hearing under this Sub-title refuses to appear, be examined, or answer any questions, or produce any books, records, papers, vouchers, accounts or documents, pertinent to the matter of inquiry, when subpoenaed so to do by the collector, or any of his authorized assistants, the collector or such assistant, in term time or vacation, may apply to any district court, upon proof by affidavit of such refusal, to make an order returnable in not less than two nor more than ten days, directing such person to show cause before the court why he should not obey the demand of the subpoena. Upon the return of such order, the court before whom the matter comes shall examine the person under oath, and the person shall be given an opportunity to be heard, and if the court determines that he has refused, without legal excuse, to obey the command of the subpoena, or to be examined, or to answer any question, or to produce any books, papers, vouchers, records, accounts, or documents, pertinent to the matter of inquiry, which he was by subpoena commanded to answer or produce, the court may order such person to comply forthwith with such subpoena or order, or to submit to such examination or to answer any such question, and any failure to obey such order of the court may be punished by the court as a contempt of the court.
