The right to labor or to trade was thus fully established in England, and from the very earliest times we find statutes that merchants may freely buy and sell. The Statute of York, to this effect (1335), is re-enacted sixteen years later, and again under Richard II in 1391; and their right to carry away one-half the value of their imports in money, spending the other half in English commodities, in 1401.
This general right of trade may be defined as the right of any man to work at what trade he chose, and to buy or sell what and where he will, in the cheapest market. This right was indeed fundamental and needed no express statute. But all these laws concerning by-laws or combinations to prevent people from exercising their trade, or showing what were the liberties of trade in London and other towns (of which there are many) are exemplifications of it. That this law is far older than the statutes is well shown by an actual law report of a case decided in 1221 and first published by the Selden Society in 1877:
“The Abbot of Lilleshall complains that the bailiffs of Shrewsbury do him many injuries against his liberty, and that they have caused proclamation to be made in the town that none be so bold as to sell any merchandise to the Abbot or his men upon pain of forfeiting ten shillings, and that Richard Peche, the bedell of the said town, made this proclamation by their orders. And the bailiffs defend all of it, and Richard likewise defends all of it and that he never heard any such proclamation made by anyone. It is considered that he do defend himself twelve-handed (with eleven compurgators), and do come on Saturday with his law.”
This is a remarkable report, for in twelve lines (ten lines of the law Latin) we have here set forth all the important principles of the law of boycott. The abbot complains that the Shrewsbury people do him many injuries “against his liberty,” i.e., the abbot claims a constitutional right to freely conduct his own business; then we have the recognition of the threat of a boycott as a particularly illegal act: “They have caused proclamation to be made that none sell merchandise to the abbot.” This is nothing but our modern “unfair list.” The defendants admit the illegality of their conspiracy, because they deny it as a fact; and the bedell likewise denies that he ever made such proclamation or threat, whereupon (the plaintiff being a man of the church) they are set to trial by wager of law instead of by actual battle, neither party nor the court making any question of the illegality both of the conspiracy and of the act complained of.
