982                                        LAWS OF MARYLAND                                Ch. 460

described in § 31 of this article, who is on leave of absence without pay from
employment with a political subdivision of the State of Maryland in order to serve
as a member of the General Assembly shall, upon application, receive service
credit in the local retirement system for the period of such absence required for
service in the General Assembly. In order to receive the benefit of the service
credits provided under this subsection the member shall contribute into the local
retirement system, at his usual rate of contribution based upon the salary of the
position from which he is on leave without pay to serve as a member of the
General Assembly. It shall be the duty of the Comptroller of the State to make
appropriate certifications as to the service credits to which such members shall be
entitled. The application of this subsection shall be limited to persons who are
members of the General Assembly from and after January 15, 1963.

(6)      Should any member in any period of six consecutive years after last
becoming a member be absent from service more than two years, or should he
withdraw all or part of his accumulated contributions, or should he become a
beneficiary or die, he shall thereupon cease to be a member; provided, however,
that any member who was absent from service for more than two years on account
of the transfer or lease to the United States of the facility or property where said
member was employed and who continued to work at the same place as an
employee of the United States until the return of the property to the State after
the war, when he again became an employee of the State, shall be entitled to credit
for all service as an employee of the State before he became an employee of the
United States as hereinbefore described and his prior service certificate shall again
become effective as if he had not ceased to be an employee of the State. However,
any such person who has withdrawn his accumulated contributions (other than one
who has become a beneficiary or died) may subsequently redeposit in the
retirement system the amount of accumulated contributions previously withdrawn,
with interest to the date of redeposit, and regain previous service credit with the
condition, however, that he may not retire within three years after the date of
reentry in the retirement system.

Any member who had terminated membership in the Teachers' Retirement
System or the State Police Retirement System may and upon deposit into the
Employees' Retirement System of the accumulated contributions previously
withdrawn from the Teachers' System or the State Police System, with interest to
date of deposit, receive credit in the Employees' System for the service that had
previously been terminated with the condition, however, that he may not retire
within three years after the date of entry in the Employees' Retirement System.

(7)    It shall be the duty of the head of each department to submit to the board
of trustees a statement showing the name, title, compensation, duties, date of birth,
and length of service of each member and such information regarding other
employees in his department as the board of trustees may require. The board of
trustees shall then place each member in one of the following groups:

Group 1. Clerical, administrative, professional and technical workers engaged in
duties requiring principally mental exertion.

Group 2. Laborers, mechanics and other workers engaged in duties requiring
principally physical exertion.

Any other group of not less than two hundred and fifty persons which may be
hereafter recommended by the actuary on the basis of service and mortality
experience and approved by the board of trustees, to cover all or part of any group
or groups previously created or any additional classes of employees.
