So we must admit that any final server (registrars) are contratual covered by national laws.Perhaps, but most probably not. Also, cross-national norms should be covered by International Conventions and/or Treaties to be granted (in less time). For a transborder court order, Brazil takes at least 6 months to a year (or more) just to answer and then start the process itself. Omar 2011/7/7 Lutz Donnerhacke <lutz@iks-jena.de>:
The usual (non LEA) user automatically follow the whois chain and can obtain the necessary information from the final server, if this access is granted by national laws (of the final Whois operator). This way the applicable laws of data collection and protection even in the light of LEA access (cross-national?) can be fullfilled without knowing all those laws in advance.
