Right to bring a witness
In principle, you have the right to be accompanied by a witness (also called an observer) to all meetings with the University, including meetings with your head of studies in cases of suspected exam cheating.

The observer is not there to argue your case and does not play an active role in the dialogue. The role of the observer is to provide support. Family members and trusted friends make good observers.
After the meeting, the witness can help you keep track of what was said and decided, so it is a good idea for the observer to take notes.
