(2) From and after July 1, 1993, each governmental entity other than political subdivisions shall participate in a comprehensive plan of self-insurance or one or more policies of liability insurance or combination of the two (2), all to be administered by the Department of Finance and Administration. The plan shall provide coverage to each of such governmental entities for every risk for which the board determines the respective governmental entities to be liable in the event of a claim or suit for injuries under the provisions of this chapter, including claims or suits for injuries from the use or operation of motor vehicles; the board may allow the plan to contain any reasonable limitations or exclusions not contrary to Mississippi state statutes or case law as are normally included in commercial liability insurance policies generally available to governmental entities. The plan may also provide coverage for liabilities outside the provisions of this chapter, including, but not limited to, liabilities arising from Sections 1983 through 1987 of Title 42 of the United States Code and liabilities from actions brought in foreign jurisdictions, and the board shall establish limits of coverage for such liabilities. Each governmental entity participating in the plan shall make payments to the board in such amounts, times and manner determined by the board as the board deems necessary to provide sufficient funds to be available for payment by the board of the costs it incurs in providing coverage for the governmental entity. Each governmental entity of the state other than the political subdivisions thereof participating in the plan procured by the board shall be issued by the board a certificate of coverage whose form and content shall be determined by the board but which shall have the effect of certifying that, in the opinion of the board, each of such governmental entities is adequately insured. Before July 1, 1993, the Board of Trustees of State Institutions of Higher Learning may provide liability coverage for each university, department, trustee, employee, volunteer, facility and activity as the board of trustees, in its discretion, shall determine advisable. If liability coverage, either through insurance policies or self-insurance retention is in effect, immunity from suit shall be waived only to the limit of liability established by the insurance or self-insurance program. From and after July 1, 1993, liability coverage established by the board of trustees must conform to the provisions of this section and must receive approval from the board. Should the board reject a plan, the board of trustees shall participate in the liability program for state agencies established by the board.
