Not always. Some minor offences are infringement offences which means you will receive a fine and it can be resolved by paying the fine. However, for more serious charges where a summons to attend court has been served or if you wish to contest the offence, court attendance is required. If you have received a summons to attend court, the consequences of not attending court could include an adverse decision being made against you in your absence, or even a warrant being issued for your arrest.
