Yes, OEA can issue a subpoena at your request. A subpoena is a command to appear at a certain time and place to give testimony. You can choose to have your local sheriff serve the subpoena. While OEA can issue a subpoena, it does not have the authority to enforce it (require the person subpoenaed to appear). The party requesting the subpoena must go to a superior or circuit court to enforce the subpoena.
