Idaho Code § 36-1502

Any person may prefer charges, based on any of the above grounds, against any hunting licensee. Such charges shall be in writing, and shall be sworn to and filed with said director. All charges, unless dismissed by the director as unfounded or trivial, shall be heard by the director or his referee as a contested case under the provisions of chapter 52, title 67, Idaho Code. The hearing shall be held either in the county where the offense is alleged to have occurred or in the county of the defendant’s residence. In the event that such licensee resides outside the state of Idaho, such notice shall be served by registered mail with return receipt, mailed to the last known address of such licensee. Any person who shall be subpoenaed before said director or his referee and shall fail to appear before him, without furnishing satisfactory reason for failure to do so, shall be subject to the penalties of contempt upon application to any district court.
