Section 64-A. Suspension and revocation of licenses

1. The inspector may
  suspend or revoke any license of master, pilot, engineer or joint  pilot
  and  engineer,  issued  pursuant to the provisions of this article, upon
  satisfactory  proof   of   recklessness,   carelessness,   intemperance,
  incompetence,  wilful  dereliction of duty or wilful disobedience of any
  rule or regulation duly made and promulgated by the commissioner.
    2. It shall  be  the  duty  of  the  inspector  to  receive  and  make
  determination  on  complaints  duly  made in writing against any master,
  pilot, engineer, or joint pilot and engineer licensed  pursuant  to  the
  provisions  of  this  article  where it appears that the license of such
  person may be subject to suspension or revocation under this section.
    3. Before any person shall be proceeded against on any  complaint  and
  before  any  license  may  be revoked or suspended, such person shall be
  notified, in writing, signed by the  inspector,  to  appear  before  the
  inspector.  Such  notice  shall specify the nature and substance of such
  complaint and shall be served personally at least five days  before  the
  time  fixed  for  appearance. The inspector may postpone or adjourn such
  hearing from time to time.
    4. The  inspector,  at  the  request  of  either  the  complaining  or
  defending  party,  shall  issue  subpoenas  to  compel the attendance of
  witnesses before the inspector in all cases which  he  is  empowered  to
  hear  and  determine  under this article. The inspector shall examine on
  oath, to be  administered  by  him,  all  such  witnesses.  Each  person
  subpoenaed  as  a witness shall be entitled to the same witness fees and
  be subject to the same penalties and punishments  for  disobedience,  or
  for  false  testimony, as would apply in a civil suit at law, in a court
  of record.
    5. Whenever the license of any master, pilot, engineer or joint  pilot
  and  engineer  is suspended or revoked he shall forthwith deliver up his
  license to the inspector. The inspector shall retain any such  suspended
  license  until  the time of suspension shall expire. Any such person who
  shall refuse to deliver up such suspended or revoked  license  shall  be
  subject  to a penalty of one hundred dollars for each day following such
  refusal.
