As suggested in the discussion of the definition of military occupation there is a prima facie case that inhabitants of occupied territory are under an obligation to obey the occupying authorities. There is indeed explicit, if qualified, reference to this idea in the current British Manual of the Law of Armed Conflict:

Yet, despite the recurrent appearance of this expectation of obedience in the law and practice of military occupation, explicit attention to the problems associated with it has been far more fitful than that devoted to the problem of political obligation in general. So much is this the case that it was possible to identify an article by Richard Baxter published in 1950 as ‘pathbreaking’; to which it might be added that the path has remained largely untrodden. That is hardly surprising for Baxter's article was a condemnation of the doctrine. Neglect of the correlative concept of the authority of the occupier has not been as marked, though here too wider considerations, in this case the tendency to confound authority with power, have contributed to the neglect.
