A “Certificate of Relief From Disabilities” may be granted to relieve an eligible offender of any forfeiture or disability, or to remove any bar to his employment, automatically imposed by law by reason of his conviction of the crime or of the offense specified therein.  Such certificate may be limited to one or more enumerated forfeitures, disabilities, or bars, or may relieve the eligible offender of all forfeitures, disabilities or bars.  Provided, however, that no such certificate shall apply, or be construed so as to apply, to the right of such person to retain or to be eligible for public office.
