If his "victims" have information that would lead to charges in a criminal court then my understanding is that the terms of the Non Disclosure Agreement would be void. But this is a grey area. Is taking the pieces of silver regarded as compensation for suffering alleged wrongdoing? A contract cannot stand if hiding criminality.

As I quoted several days ago:
The Solicitors Regulation Authority has issued a warning notice reminding law firms that non-disclosure agreements must never be misused as a way of covering up sexual misconduct in the workplace. This comes at a time when sexual harassment claims across all kinds of industries are rife. As a matter of law, NDAs cannot be used to prevent the victim from making protected disclosures to relevant bodies.

We have many wild and lurid allegations about his character and behaviour but nothing of substance. There are several here happy to abuse the man because they do not like him and have read unsavoury allegations about him in the gutter press. Do we have any proof?
   
Do the alleged "victims" feel the money is of more importance than seeking redress in the courts for alleged criminal activity.
The "victim" can report suspected criminal acts. If such acts are considered to have wings the crown prosecution service will make it fly.

Also the lawyers drafting such agreements would also be liable to sanction. It makes a person wonder if the wrongdoing being hidden is more causing him embarrassment, rather than actual criminality.
As yet all these procedures are in Civil, not criminal court. Some here should perhaps consider why that is!
