If you get a witness summons
Getting a witness summons means you'll have to be at the court on the day of the trial and give evidence if you're asked to.
You should go to court if you get a summons - you can be arrested and taken to the court by the police if you don't.
You might get a summons from the court if:
they haven't been able to contact you with a witness warning
they think you might not come on the day
you've said you won't go to court
you were told the date of the trial and you didn't turn up
If your employer has said they won't give you time off, the court could give you a summons to show your employer.
