The board shall have the power to make all bylaws and rules, not inconsistent with the constitution and laws of this state, which may be reasonably necessary for the proper performance of its duties and the regulations of the proceedings before the board. Notwithstanding any other provision of law, following appropriate review by the Contract Review Permanent Legislative Oversight Committee, the board may enter into any contract or agreement relating to the board without further approval. The board shall adopt and have an official seal. In carrying into effect the provisions of this chapter, the board may, under the hand of its chairman and the seal of the board, subpoena witnesses and compel their attendance and may also require them to produce books, papers, maps, or documents. Any member of the board may administer oaths of affirmation to witnesses appearing before the board. Witnesses officially called by the board shall receive the same compensation and shall be reimbursed for expenses in the same amount as the members of the board as provided and set out in Section 34-12-4. If any person shall refuse to appear as a witness before the board, or refuse to testify, or refuse to produce any books, papers, or documents, the board may present its petition to the Circuit Court of Montgomery County, setting forth the facts, and the court shall, in a proper case, issue a subpoena to the person, requiring his or her attendance before the circuit court and there to testify or to produce such books, papers, and documents as may be deemed necessary and pertinent by the board. Any person failing or refusing to obey the subpoena or order of the circuit court may be proceeded against in the same manner as for refusal to obey any other subpoena or order of the court. The board is empowered to apply for relief by injunction, without bond, to restrain any person, partnership, or corporation from the commission of any act which is prohibited by this chapter. Application for an injunction may be made to the Circuit Court of Montgomery County, Alabama, or the circuit court of the county in which it is alleged that the violation is occurring. The members of the board shall not be personally liable for instituting any such proceedings.
