“Subjects of the Crown, British citizens, are in a different boat. International law does not prevent a state from exercising jurisdiction over its nationals travelling or residing abroad, since they remain under its personal authority: Oppenheim’s International Law , 9th ed (1992), vol 1, Pt I, para 138. So there can be no objection in principle to Parliament legislating for British citizens outside the United Kingdom, provided that the particular legislation does not offend against the sovereignty of other states.”
“the public shall have access to information…without discrimination as to citizenship, nationality or domicile, and in the case of a legal person, without discrimination as to where it has its registered seat or its effective centre of its activities”
