Don’t think international courts will care about broadcasting rights.

Any court - international or domestic, whether they care or don't - will come to the same conclusion because the law is pretty clear: all FIFA World Cup games have to be offered live and in their entirety to free-to-air broadcasters. FIFA can try and sell to a streamer or pay TV channel, but they would then be obligated to allow at least one free-to-air broadcaster to simulcast all their matches. This would make it a commercially unappetising purchase in the first place as the BBC and/or ITV would not even have to compensate them.

FIFA could, of course, try and get the law changed, but such a move would be highly unpopular and so I doubt any government would seriously entertain it. They could try and challenge the law in court, but the Ofcom code is perfectly legal and has even stood up under the notoriously deregulatory EU competition law (which would, of course, no longer even apply). Ultimately, the current arrangement is probably in FIFA's best interests as I expect that, given the above circumstances, no streamer/pay broadcaster in their right mind would pay more than the BBC and ITV currently pay.
