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[]: 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, examples have happened within a century past, where an embassador has been punished for any offence, however atrocious in it's nature.

In respect to civil suits, all the foreign jurists agree, that neither an embassador, nor any of his train or comites, can be prosecuted for any debt or contract in the courts of that kingdom wherein he is sent to reside. Yet sir Edward Coke maintains, that, if an embassador make a contract which is good jure gentium, he shall answer for it here[n]. And the truth is, we find no traces in our lawbooks of allowing any privilege to embassadors or their domestics, even in civil suits, previous to the reign of queen Anne; when an embassador from Peter the great, czar of Muscovy, was actually arrested and taken out of his coach in London, in 1708, for debts which he had there contracted. This the czar resented very highly, and demanded (we are told) that the officers who made the arrest should be punished with death. But the queen (to the amazement of that despotic court) directed her minister to inform him, "that the law of England had not yet protected embassadors from the payment of their lawful debts; that therefore the arrest was no offence by the laws; and that she could inflict no punishment upon any, the meanest, of her subjects, unless warranted by the law of the land[o]." To satisfy however the clamours of the foreign ministers (who made it a common cause) as well as to appease the wrath of Peter[p], a new statute was enacted by parliament[q], reciting the arrest which had been made, "in contempt of the protection granted by her majesty, contrary to the law of nations, and in prejudice of the rights and privileges, which embassadors and other public ministers have at all times been thereby possessed of, and ought to be kept sacred and inviolable:" wherefore it enacts, that for the future all process whereby the person of any embassador, or of his domestic or domestic servant, may be arrested, or his goods distreined or seised, shall be utterly null and void; and the persons prosecuting, soliciting, or executing such process shall be deemed violaters of the law of nations, and disturbers of the public repose; and shall suffer such penalties and corporal punishment as the lord chancellor and the two chief justices, or any two of them, shall think fit. But it is expressly provided, that no trader, within the description of the bankrupt laws, who shall be in the service of any embassador, shall be privileged or protected by this act; nor shall any one be punished for arresting an embassador's servant, unless his name be registred with the secretary of state, and by him transmitted to the sheriffs of London and Middlesex. Exceptions, that are strictly conformable to the rights of embassadors[r], as observed in the most civilized countries. And, in consequence of this statute, thus enforcing the law of nations, these privileges are now usually allowed in the courts of common law[].
