Louisiana Revised Statutes Tit. 13, § 5004. Personal appearance of defendant judge

The Supreme Court, in all such cases, when the incompetency of the defendant judge, arising out of want of sufficient learning, or mental incapacity, shall be at issue, may cause such defendant, on its own motion, or on that of any party to the suit, or of any of the persons at whose request the same is instituted, to appear before it in person, in open session, there and then to answer any pertinent questions that may be put to him. Should the court over which such judge presides be in session at the same time with the session of the Supreme Court at which the case is to appear, the personal appearance of such judge shall not be required until such time as he may do so without interfering with and interrupting the session of his court.
