A majority of each of the boards of commissioners of pilotage may take away the license of a pilot for a given time or declare his license null and void, as the nature of the case may demand (a) upon charge of any dereliction of duty made and proven against him, (b) if he be found guilty of using abusive or insulting language or of threatening conduct, while on his business as a pilot or (c) if charges of intoxication or conduct unbecoming a pilot, either when on or off duty, be proved against him to the satisfaction of a majority of the commissioners. But any pilot against whom any charge shall be made shall be entitled to a hearing before the board of commissioners and to make any proper defense to such charge. Any decision by the board to suspend, revoke, or otherwise restrict the license of a pilot shall be subject to review by an Administrative Law Judge as provided under Article 5 of Chapter 23 of Title 1.
