(1436) Now, perhaps, we find the first use of the expression "restraint of trade," that most important phrase, in a statute forbidding by-laws of guilds or corporate companies "in restraint of trade," also forbidding unlawful ordinances by them as to the price of their wares "_for their own profit and to the common, hurt of the people_," and such by-laws are made penal and invalid except when approved by the chancellor; and this statute of Henry VI is re-enacted again in 1503 under Henry VII, where by-laws of guilds, etc., restraining suits at law are made unlawful, and so "_ordinances against the common weal of the people_." The meaning and importance of such legislation as this has been, I hope, made clear above. Note the words "_to the common hurt of the people_" and "_against the common weal of the people_." From this century, at least, therefore, dates that doctrine of the common law which makes unlawful any contract or combination in restraint of trade, and it was left for the succeeding century to develop the last great principle, that against monopoly, caused either by unlawful combination of individuals or grant by the crown itself. 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."
