The principle thus apparently established by custom was overthrown by a succession of legal decisions, culminating in the famous Somersett Case. It was first decided by Thomas Grahame, judge in the Admiralty Court, Glasgow, that a certain negro who had been brought into Great Britain must be liberated, on the ground that a guiltless human being taken into that country must be free.[41] In 1762 occurred another similar case. A bill had been filed in equity by an administrator to recover money given by his intestate to a negro brought to England as a slave. The suit was dismissed by Lord Northington, who said that as soon as a man set foot on English ground he was free.[42] The Somersett case came ten years later. The circumstances were as follows. A Mr. Stewart, accompanied by his slave Somersett, left Boston on the 1st of October, 1769, and went to London, where he kept his slave until October 1, 1771. Then Somersett ran away, but his owner soon secured him and had him placed on board a vessel bound for Jamaica, probably with the intention of selling him as a slave. A writ of habeas corpus was then served upon the captain of the ship, and on the hearing Lord Mansfield decided that Somersett must be discharged. In England, he said, slavery could exist only by positive law; and in default of such law there was no legal machinery for depriving a man of his liberty on the ground that he was a slave. The importance of the case for the colonies lay not in the assertion of the principle that slavery depended on positive law, for the American statute-books were full of positive law on slavery; the precedent thus established determined the future course of England against the delivery of fugitives, whether from her colonies or from other countries.[43] =§ 13. International regulations under the Articles of Confederation (1781-1788).=--When, on March 1, 1781, the Articles of Confederation went into effect, the only action taken by the United States on the subject of fugitives had been the negotiation of a treaty with the Delaware Indians, August 7, 1778, by which the parties bound themselves not "to protect in their respective States criminal fugitives, servants, or slaves, but the same to apprehend, secure, and deliver."[44] In seven of the eight other treaties negotiated with Indian tribes from 1784 to 1786, clauses were introduced for the return of black prisoners, or of "negroes and other property."[45] The States affected were chiefly Southern; but the article on the same subject in the Treaty of Peace in 1782 and 1783, was intended as much to protect the slaveholders of New York as those of Virginia. It was distinctly agreed that the British should not carry away "any negroes or other property."[46] The failure to abide by this agreement led to reclamation by the American government, but no indemnity was ever secured.[47] [Sidenote: English Law.
