The Unconstitutionality of Slavery

by Lysander Spooner

But although there is, in this statute, no authority given for—but, on the contrary, a special prohibition upon—the transportation of the natives from Africa against their will, yet I freely admit that the statute contains one or two strong, perhaps decisive implications in favor of the fact that slavery was allowed in the English settlements on the coast of Africa, apparently in conformity with the customs of the country, and with the approbation of parliament. But that is the most that can be said of it. Slavery, wherever it exists, is a local institution; and its toleration, or even its legality, on the coast of Africa, would do nothing towards making it legal in any other part of the English dominions. Nothing but positive and explicit legislation could transplant it into any other part of the empire.

The implications, furnished by the act, in favor of the toleration of slavery, in the English settlements, on the coast of Africa, are the following:

The third section of the act refers to another act of parliament "divesting the Royal African Company of their charter, forts, castles and military stores, canoe-men and castle-slaves;" and section thirty-first requires that such "officers of his majesty's navy," as shall be appointed for the purpose, "shall inspect and examine the state and condition of the forts and settlements on the coast of Africa, in the possession of the Royal African Company, and of the number of soldiers therein, and also the state and condition of the military stores, castles, slaves, canoes and other vessels and things, belonging to the said company, and necessary for the use and defence of the said forts and settlements, and shall with all possible despatch report how they find the same."

Here the fact is stated that the "Royal African Company," (a company that had been in existence long previous to the passing of this act,) had held "castle-slaves" "for the use and defence of the said forts and settlements." The act does not say directly whether this practice was legal or illegal; although it seems to imply that, whether legal or illegal, it was tolerated with the knowledge and approbation of parliament.

But the most distinct approbation given to slavery by the act, is implied in the 28th section, in these words:

"That it shall and may be lawful for any of his majesty's subjects trading to Africa, for the security of their goods and slaves, to erect houses and warehouses, under the protection of the said forts," &c.

Although even this language would not be strong enough to overturn previously established principles of English law, and give the slave holders a legal right of property in their slaves, in any place where English law had previously been expressly established, (as it had been in the North American colonies,) yet it sufficiently evinces that parliament approved of Englishmen holding slaves in the settlements on the coast of Africa, in conformity with the customs of that country. But it implies no authority for transporting their slaves to America; it does nothing towards legalizing slavery in America; it implies no toleration even of slavery any where, except upon the coast of Africa. Had slavery been positively and explicitly legalized on the coast of Africa, it would still have been a local institution.

This reasoning may appear to some like quibbling; and it would perhaps be so, were not the rule well settled that nothing but explicit and irresistible language can be legally held to authorize anything inconsistent with natural right, and with the fundamental principles of a government.

That this statute did not legalize the right of property in man, (unless as a local principle on the coast of Africa,) we have the decision of Lord Mansfield, who held that it did not legalize it in England; and if it did not legalize it in England, it did not legalize it in any of the colonies where the principles of the common law prevailed. Of course it did not legalize it in the North American colonies.

But even if it were admitted that this statute legalized the right of property, on the part of the slave trader, in his slaves taken in Africa after the passage of the act, and legalized the sale of such slaves in America, still the statute would be ineffectual to sustain the legality of slavery, in general, in the colonies. It would only legalize the slavery of those particular individuals, who should be transported from Africa to America, subsequently to the passage of this act, and in strict conformity with the law of this act—(a thing, by the way, that could now be proved in no case whatever.) This act was passed in 1749-50, and could therefore do nothing towards legalizing the slavery of all those who had, for an hundred and thirty years previous, been held in bondage in Virginia and elsewhere. And as no distinction can now be traced between the descendants of those who were imported under this act, and those who had illegally been held in bondage prior to its passage, it would be of no practical avail to slavery now, to prove, (if it could be proved,) that those introduced into the country subsequent to 1750, were legally the property of those who introduced them.
