Any public employee in service on July 1, 1985, who ceases to be a public employee on or after that date and who subsequently again becomes a public employee shall be subject to the provisions of Code Section 47-1-22 upon again becoming a public employee. Any person who was a public employee prior to July 1, 1985, and who ceased to be a public employee prior to that date shall be subject to the provisions of Code Section 47-1-22 if such person again becomes a public employee after July 1, 1985.

(b) If a public employee commits a public employment related crime on or after July 1, 1985, in the capacity of a public employee and is convicted for the commission of such crime, such employee's membership in any public retirement system shall terminate on the date of final conviction and such employee shall not at any time thereafter be eligible for membership in any public retirement system. For any such public employee finally convicted for the commission of a public employment related crime, the right to any benefit or any other right under any public retirement system in which the employee is a member shall be determined as of the date of final conviction.
