(1) The interstate commission shall, by a majority of commissioners present and voting, adopt bylaws to govern its conduct as may be necessary or appropriate to carry out the purposes of the compact within twelve months of the first interstate commission meeting.

(2) The interstate commission shall elect or appoint annually from among its commissioners a chair, a vice chair, and a treasurer, each of whom shall have such authority and duties as may be specified in the bylaws. The chair, or in the chair's absence or disability, the vice chair, shall preside at all meetings of the interstate commission.

(3) Officers selected in subsection (2) of this section shall serve without renumeration from the interstate commission.

(4) The officers and employees of the interstate commission shall be immune from suit and liability, either personally or in their official capacity, for a claim for damage to or loss of property or personal injury or other civil liability caused or arising out of, or relating to, an actual or alleged act, error, or omission that occurred, or that such person had a reasonable basis for believing occurred, within the scope of interstate commission employment, duties, or responsibilities, provided that such person shall not be protected from suit or liability for damage, loss, injury, or liability caused by the intentional or willful and wanton misconduct of such person.

(a) The liability of the executive director and employees of the interstate commission or representatives of the interstate commission, acting within the scope of such person's employment or duties for acts, errors, or omissions occurring within such person's state, may not exceed the limits of liability set forth under the Constitution and laws of that state for state officials, employees, and agents. The interstate commission is considered to be an instrumentality of the states for the purposes of any such action. Nothing in this subsection shall be construed to protect such person from suit or liability for damage, loss, injury, or liability caused by the intentional or willful and wanton misconduct of such person.

(b) The interstate commission shall defend the executive director, its employees, and subject to the approval of the attorney general or other appropriate legal counsel of the member state represented by an interstate commission representative, shall defend such interstate commission representative in any civil action seeking to impose liability arising out of an actual or alleged act, error, or omission that occurred within the scope of interstate commission employment, duties, or responsibilities, or that the defendant had a reasonable basis for believing occurred within the scope of interstate commission employment, duties, or responsibilities, provided that the actual or alleged act, error, or omission did not result from intentional or willful and wanton misconduct on the part of such person.

(c) To the extent not covered by the state involved, member state, or the interstate commission, the representatives or employees of the interstate commission shall be held harmless in the amount of a settlement or judgment, including attorneys' fees and costs, obtained against such persons arising out of an actual or alleged act, error, or omission that occurred within the scope of interstate commission employment, duties, or responsibilities, or that such persons had a reasonable basis for believing occurred within the scope of interstate commission employment, duties, or responsibilities, provided that the actual or alleged act, error, or omission did not result from intentional or willful and wanton misconduct on the part of such persons.
