They can request what ever they want. I mean "Send a minimum $5 for each photo you take" is one approach but you can't make that stick.
The NFL probably has the most famous disclaimer "Any accounts blah blah blah" which simply means that you can not copy work that they did or commissioned done. If you take a picture of a game in progress you own that picture and can do with it as you please.
I'd think the same would hold true in any sort of international court. Pictures of public buildings are permitted. Period.
I know for sure that they try and bully people into paying though. I should really test that theory and post a picture anyway, and upvote myself for like 10 cents.
I wonder if they'd find that and try and squeeze some money out of me.
