Pleading guilty means that you admit fully and unconditionally to the offence committed. The prosecuting officer will then read out the Statement of Facts (SOF) relating to your charge and any previous convictions that you may have. Your plea of guilt will be accepted when you admit to the SOF and previous convictions.
Before the Court passes sentence, you will be asked if you have any mitigating factors for the Court to consider. A "plea in mitigation" is when you ask the court to be lenient when imposing sentence. You should state specific reasons for the Court to impose a lighter sentence than it normally would. For example, family background, educational qualification, medical history, employment history and relevant factors which gave rise to the offence.
