How would you deal with this?

It's an ex husband rant. DS1's father says he wants extra access. I said I would consider it if we could come to some agreement regarding schooling and dealing consistently with DS's bladder problems but he continues to push for a secondary school that would really not be good for DS and consistently goes against the advice of the bladder and bowel nurse so there's no way I'm going to agree.
Then a couple of days ago he emailed stating that he will be picking DS up from school on a Thursday having him overnight and then having him for the weekend as normal.  In the terms of our divorce any extra access is by mutual agreement only so how on earth can he think he can do this and what can I do to stop him? I don't want DS to be stuck in the middle of this. Every time I think about it I want to scream.
