Dormouse, no. He can''t be forced to attend mediation. He can''t be prevented from acting like a complete idiot.
Don''t worry about the CSA ( don''t know whether it should be CMEC but you know what I mean ). The Courts have no jurisdiction so you are wasting everyone''s time trying to bring it up in Court.
Leave that to the CSA.
If he insists on playing silly beggars you have to go to Court. There is no alternative, as a certain someone used to say. He''s a damn fool if he does not come, because the Court only hears your side of the story .
And if you have incurred avoidable expense due his silly tricks, ask for an order for him to reimburse you. You might not get it, but I''d ask.
