§ 171. As through occupation authority over the territory actually passes into the hands of the occupant, he may for the time of his occupation depose all Government officials and municipal functionaries that have not withdrawn with the retreating enemy. On the other hand, he must not compel them by force to carry on their functions during occupation, if they refuse to do so, except where a military necessity for the carrying on of a certain function arises. If they are willing to serve under him, he may make them take an oath of obedience, but not of allegiance, and he may not compel them to carry on their functions in his name, but he may prevent them from doing so in the name of the legitimate Government.[340] Since, according to article 43 of the Hague Regulations, he has to secure public order and safety, he must temporarily appoint other functionaries in case those of the legitimate Government refuse to serve under him, or in case he deposes them for the time of the occupation. [Footnote 340: Many publicists assert that in case an occupant leaves officials of the legitimate Government in office, he "must" pay them their ordinary salaries. But I cannot see that there is a customary or conventional rule in existence concerning this point. But it is in an occupant's own interest to pay such salaries. and he will as a rule do this. Only in the case of article 48 of the Hague Regulations is he compelled to do it.] [Sidenote: Position of Courts of Justice during Occupation.]
