"International Court order"
I'm sorry but what, pray tell, is one of those?
You do realise that there's no such thing as the "International Court", right? The closest thing would be the International Court of Justice, which is a wholly inappropriate forum for something as mundane as the take-down of a domain name (it mostly deals with disputes between states).
Where an offence is committed, LEAs will rightly want to cease any ongoing criminal activity and it is justified for their courts to support them. It just amazes me that courts have not yet thought in sufficient detail about the offence the LEA is attempting to cease: in most cases it is the provision of a machine's (unlawful) service into their jurisdiction, for which the correct remedy would be to block such communication - not remove the ability to locate such machine through the DNS, which of course is not a solution at all.
Should it really be necessary to prevent name resolution, such an order from a court ought apply only to DNS resolvers within their jurisdiction. Perhaps the "best" way to enforce this would be to create shadow roots and redirect to them any traffic destined for the actual roots but originating within one's jurisdiction. (NB: I fear the consequences an inconsistent DNS would have on the stability of the Internet almost as much as I fear the threat of more sinister state interference in DNS records.)
I find it genuinely hard to imagine a situation where a domain name registration could itself constitute an offence, irrespective of the activity undertaken with such a registration, and it amazes me that courts have gone along with such a(n implied) suggestion. If they woke up to this argument, I think the whole debate over jurisdiction for take-down orders would disappear into irrelevance.
