It is the intent of this chapter to protect state officers, trustees, officials, employees, and members of the general court who are subject to claims and civil actions arising from acts committed within the scope of their official duty while in the course of their employment for the state and not in a wanton or reckless manner. It is not intended to create a new remedy for injured persons or to waive the state’s sovereign immunity which is extended by law to state officers, trustees, officials, and employees. The doctrine of sovereign immunity of the state, and by the extension of that doctrine, the official immunity of officers, trustees, officials, or employees of the state or any agency thereof acting within the scope of official duty and not in a wanton or reckless manner, except as otherwise expressly provided by statute, is hereby adopted as the law of the state. The immunity of the state’s officers, trustees, officials, and employees as set forth herein shall be applicable to all claims and civil actions, which claims or actions arise against such officers, trustees, officials, and employees in their personal capacity or official capacity, or both such capacities, from acts or omissions within the scope of their official duty while in the course of their employment for the state and not in a wanton or reckless manner.
