When your case is called on, you will go into the court and go behind the security screen. This is the dock area.
The court clerk will then ask you to confirm your name etc.
Next, the court clerk will read out the charge that you face.
You will then enter a plea of either guilty or not guilty.
If you plead guilty, the prosecution will give a quick summary of the what happened.
The court would then hear from your solicitor.
The court would the. Whether they can sentence you.
Possession class B is an either way offence, which means it can be dealt with in the Magistrates court or the crown court.
For such a small amount the court would say they will keep,the case and the sentence you.
For class B, if the amount is so small, and if this is your first time in trouble, on a guilty please, the starting point for the offence is a fine, then the court can either increase the sentence to a higher fine or community service or reduce it to a conditional discharge .
Your previous good character, guilty plea and such a small amount would no doubt keep the sentence either at the starting point of a fine or reduce it to a conditional discharge. That would then be the end of the matter.
