If the data in question is protected by a foreign law from being disclosed to anyone, such as personal information protected by the EU, then if the company were to disclose this information to a third party such as the court, it would be in violation of that country's laws. Damn if you do and damned if you don't. Who do you want to piss off more? International law is highly complex and probably shouldn't be handled by judges at a local level. I would expect the state department would get involved, as it might cause all sorts of grief to the country.
