  as provided in this chapter or otherwise especially provided, shall have
  or  employ  any attorney or counsel, except where a judgment or order in
  an action or proceeding may affect such officer or  agency  individually

  case such officer or agency may employ and be represented by attorney or
  counsel at their own expense.
