Section 35-A. Limitation of time for revocation of permit

An action or
  proceeding to revoke a building permit on the ground that  the  building
  erected  pursuant  thereto stands wholly or partly within the bed of any
  street or highway shown on the official map or plan of a  city  must  be
  commenced  within  fifteen  years  from the time of the issuance of such
  permit; but if at the time this act  takes  effect  more  than  fourteen
  years  have  elapsed  since  the  time of the issuance of the permit, an
  action or proceeding to  revoke  the  permit  on  such  ground  must  be
  commenced  within  one  year  from the time this act takes effect. If no
  action or proceeding is commenced within the time  limited,  the  permit
  shall  be  deemed  as  valid  as  if  it had been issued pursuant to the
  provisions of section thirty-five of this chapter.
