That will vary, depending on the nature of the Code violation. Each hearing will be conducted by the ALJ. The ALJ is a licensed Illinois attorney appointed by the Village Manager to preside over the hearing as an independent and impartial decision maker.
The Village of Niles, as the petitioner, will have a prosecutor and/or representative there to present its case. The Village may also bring witnesses to support its case. You may represent yourself. You may also hire an attorney to represent you at your own expense. If you are represented by an attorney, an Attorney Appearance form is required <available here>.
The hearings are open to the public; therefore, other people may be present during your hearing.
