I. THE king therefore, considered as the representative of his people, has the sole power of sending embassadors to foreign states, and receiving embassadors at home. This may lead us into a short enquiry, how far the municipal laws of England intermeddle with or protect the rights of these messengers from one potentate to another, whom we call embassadors. THE rights, the powers, the duties, and the privileges of embassadors are determined by the law of nature and nations, and not by any municipal constitutions. For, as they represent the persons of their respective masters, who owe no subjection to any laws but those of their own country, their actions are not subject to the control of the private law of that state, wherein they are appointed to reside. He that is subject to the coercion of laws is necessarily dependent on that power by whom those laws were made: but an embassador ought to be independent of every power, except that by which he is sent; and of consequence ought not to be subject to the mere municipal laws of that nation, wherein he is to exercise his functions. If he grossly offends, or makes an ill use of his character, he may be sent home and accused before his master[e]; who is bound either to do justice upon him, or avow himself the accomplice of his crimes[f]. But there is great dispute among the writers on the laws of nations, whether this exemption of embassadors extends to all crimes, as well natural as positive; or whether it only extends to such as are _mala prohibita_, as coining, and not to those that are _mala in se_, as murder[g]. Our law seems to have formerly taken in the restriction, as well as the general exemption. For it has been held, both by our common lawyers and civilians[h], that an embassador is privileged by the law of nature and nations; and yet, if he commits any offence against the law of reason and nature, he shall lose his privilege[i]: and that therefore, if an embassador conspires the death of the king in whose land he is, he may be condemned and executed for treason; but if he commits any other species of treason, it is otherwise, and he must be sent to his own kingdom[k]. And these positions seem to be built upon good appearance of reason. For since, as we have formerly shewn, all municipal laws act in subordination to the primary law of nature, and, where they annex a punishment to natural crimes, are only declaratory of and auxiliary to that law; therefore to this natural, universal rule of justice embassadors, as well as other men, are subject in all countries; and of consequence it is reasonable that wherever they transgress it, there they shall be liable to make atonement[l]. But, however these principles might formerly obtain, the general practice of Europe seems now to have adopted the sentiments of the learned Grotius, that the security of embassadors is of more importance than the punishment of a particular crime[m]. And therefore few, if any,
