(a) When a judge of any district court of this state, acting in his capacity as magistrate, has probable cause to believe that an offense has been committed against the laws of this state, he may request that the presiding judge of the administrative judicial district appoint a district judge to commence a Court of Inquiry. The judge, who shall be appointed in accordance with Subsection (b), may summon and examine any witness in relation to the offense in accordance with the rules hereinafter provided, which procedure is defined as a “Court of Inquiry”.
(b)(1) Before requesting the presiding judge to appoint a district judge to commence a Court of Inquiry, a judge must enter into the minutes of his court a sworn affidavit stating the substantial facts establishing probable cause that a specific offense has been committed against the laws of this state.

(2) After the affidavit has been entered into the minutes of his court and a copy filed with the district clerk, the judge shall request the presiding judge of the administrative judicial district in which the affidavit is filed to appoint a judge to commence the Court of Inquiry. The judge appointed to commence the Court of Inquiry shall issue a written order commencing the Court of Inquiry and stating its scope. The presiding judge shall not name the judge who requests the Court of Inquiry to preside over the Court of Inquiry.
(c) The district or county attorney of the district or county in which the Court of Inquiry is held shall assist the district judge in conducting the Court of Inquiry. The attorney shall examine witnesses and evidence admitted before the court to determine if an offense has been committed and shall render other assistance to the judge as is necessary in the proceeding.
(d) If the Court of Inquiry pertains to the activities of the district or county attorney or to the attorney’s office, deputies, or employees, or if the attorney is otherwise disqualified in the proceeding, the judge shall appoint one attorney pro tem to assist in the proceeding. In any other circumstance, the judge may appoint an attorney pro tem to assist in the proceeding.
(e) If more than one Court of Inquiry is commenced which pertains to the activities of a state governmental entity or public servant thereof, then, upon motion of the state governmental entity or public servant, made to the presiding judge or judges of the administrative judicial region or regions where the Courts of Inquiry have been commenced, the presiding judge or judges shall transfer the Courts of Inquiry to the presiding administrative judge of Travis County. The presiding administrative judge of Travis County shall consolidate the Courts of Inquiry for further proceedings and shall assign a district judge to preside over the consolidated Courts of Inquiry.
