(a) The West Virginia State Police Retirement System is continued. It is contemplated that substantially all of the members of the retirement system shall be qualified public safety employees as defined in section two of this article. Any West Virginia state trooper employed by the agency on or after the effective date of this article shall be a member of this retirement system and may not qualify for membership in any other retirement system administered by the board so long as he or she remains employed by the State Police: Provided, That any state trooper who has concurrent employment in an additional job or jobs which would require the state trooper to be a member of the West Virginia Deputy Sheriff Retirement System, the West Virginia Municipal Police Officers and Firefighters Retirement System or the West Virginia Emergency Medical Services Retirement System shall abide by the statutory provisions of said retirement system related to concurrent employment and participate in only one retirement system administered by the board.

(b) Any individual who is a leased employee shall not be eligible to participate in the system. For purposes of this system, a "leased employee" means any individual who performs services as an independent contractor or pursuant to an agreement with an employee leasing organization or other similar organization. If a question arises regarding the status of an individual as a leased employee, the board has final power to decide the question.

(c) The board created pursuant to article ten-d, chapter five of this code shall administer the retirement system. The board may sue and be sued, contract and be contracted with and conduct all the business of the system in the name of the West Virginia State Police Retirement System.

(d) This fund is intended to meet the federal qualification requirements of Section 401(a) and related sections of the Internal Revenue Code as applicable to governmental plans. Notwithstanding any other provision of state law, the board shall administer the retirement system to fulfill this intent for the exclusive benefit of the employees, members, retirants and their beneficiaries. Any provision of this article referencing or relating to these federal qualification requirements shall be effective as of the date required by federal law. The board may promulgate rules and amend or repeal conflicting rules in accordance with the authority granted to the board pursuant to section one, article ten-d, chapter five of this code to assure compliance with this section.
