Thank you for your response although I'm still a little confused. You say it's unlikely that they would be able to get a restraining order which I understand, and a different order which would prevent him from contacting the police or his solicitors save for reasonable circumstances would be possible, but what effect would that have if he intends on taking this further anyway? If he wants to tell his solicitors to proceed that that would surely be deemed a 'reasonable' circumstance. You mention suing him for harassment but that would no doubt be the costliest and most stressful option, no?
Surely the burden of proof is on him rather than on my parents to prove he is making false accusations?
Ok, thank you. So it appears suing him would be the most effective solution. Would there be any way to ask that his mental health be assessed/taken into consideration? I am fairly confident this has influenced his behaviour, given the absurd nature of his claims. Surely there must be some way of taking this into account when defending oneself against these?
Thank you again. Finally, assuming this did go to court and my parents were to have to pay legal fees, what are the chances of being able to recoup these from the accuser if the case is thrown out/he loses?
That's great, thank you for your time.
