  thereon, are suspended during his or her active membership in the police
  and fire retirement system. He or she shall contribute to the retirement
  system as a new member.

  providing for pensions and annuities for civil service employees, wholly
  or  partly  at  the  expense  of the state or of a political subdivision
  thereof, shall not be a member of the police and fire retirement system.
  This provision, however, shall not:
1. Affect the membership of any person who was a  member  of  the  New
  York  state  and  local  employees'  retirement  system  on April first,
  nineteen hundred sixty-seven and who became a member of the  police  and
  fire retirement system after such date.

  of  this  chapter  except  where  his  position  was or is excluded from

  old-age  and  survisors  insurance  coverage  to it and such eligibility
  shall not have been restored.
f. Termination of  membership.  Membership  in  the  police  and  fire
  retirement  system  shall  cease  upon  the occurrence of any one of the
  following conditions:
1. When seven years have elapsed since a member has  performed  police
  and/or  fire  service provided, however, that no part of such seven year
  period shall run during such time as a member, with at least five  years
  of  member  service credit, shall serve as an officer or employee of the

  organizations of which the United States of America is a member.

  contributions  pursuant to the provisions of any section of this article
  or borrowing from his fund in the retirement system pursuant to  section
  three  hundred fifty of this article shall not terminate his membership.
  Acceptance of such a refund of excess contributions by a member entitled
  to a vested retirement  allowance  pursuant  to  section  three  hundred
  seventy-six of this chapter shall not terminate his right to such vested
  retirement  allowance  nor  shall  acceptance  by him of a refund of the
  amount of his contributions and regular interest  thereon  which  is  in
  excess  of  the  amount  of the accumulated contributions which he would
  then have to his credit had he been contributing on  the  basis  of  his
  rate   of  normal  contribution  terminate  his  right  to  such  vested
  retirement allowance.

  allowance or a vested retirement allowance has discontinued service with
  the  state  or  a participating employer for a period of at least thirty
  consecutive days and has requested termination of membership on  a  form
  prepared  by  the  comptroller for such purpose by filing such form with
  the comptroller. If such  person  subsequently  rejoins  the  retirement
  system  within five years from the date he discontinued service with the
  state or a participating employer, such  person  shall  be  entitled  to
  every  retirement  right,  benefit  and  privilege which would have been
  available to him had  he  reentered  employment  on  the  date  of  such
  discontinuance from service.
g.  As  to any class of persons whose compensation is only partly paid
  by the state or a  participating  employer  or  who  are  serving  on  a
  temporary  or  other  than  per  annum  basis,  the  comptroller  in his
  discretion, may:
1. Deny the right to become members, or
2. Make optional the individual entrance  of  those  whose  membership
  otherwise would be mandatory.
