@ treviCH - genau, wir sind einer Meinung. Public international law is Völkerrecht, as opposed to private international law, or conflict of laws (Internationales Privatrecht), whereby the "public" (perhaps laziness) is often omitted, except in the title of text books (cf the American Journal of International Law, the British Yearbook of International Law, etc). The Quellen given suggested a European law context, hence my suggestion of supranational, which I agree would not be appropriate in the case of a bilateral international agreement, although in some countries, which have parliamentary ratification (e.g. Germany), such bilateral agreements do take precedence (as lex specialis?) over other domestic law. This is not so in the case of the UK, where international agreements are ratified under the prerogative, unless legislative effect has been given to the agreement, as is often the case.
