Item, it is enacted, that no man great nor small, of what condition soever he be, except the King's servants in his presence, and his ministers in executing of the King's precepts, or of their office, and such as be in their company assisting them, and also [upon a cry made for arms to keep the peace, and the same in such places where such acts happen,] be so hardy to come before the King's justices, or other of the King's ministers doing their office, with force and arms, nor bring no force in affray of the peace, nor to go nor ride armed by night nor by day, in fairs, markets, nor in the presence of the justices or other ministers, nor in no part elsewhere, upon pain to forfeit their armour to the King, and their bodies to prison at the King's pleasure.[1]
The modern relevance of the legislation has been disputed: firearms did not exist at the time, and it is not immediately clear whether "nor to go nor to ride armed" (originally ne de chivaucher ne de daler arme in Anglo-Norman French) referred to carrying weapons or to wearing armour; it is also not clear whether it should be read primarily as permitting riding armed in the context of an official militia or posse, or as a prohibition in other situations.[2]
Qui tam
Chapter 15 regulated fairs and in particular required a lord to follow a royal charter or established usage to keep a fair open "for the Time that they ought to hold it, and no longer," with pre-publication of the closing time, subject to a fine for the lord and grievous punishment for the merchants if the fair stayed open longer.
Enforcement against sales after the closing time of the fair was strengthened three years later with qui tam provisions in the Sale of Wares after Close of Fair Act 1331 (5 Edw. 3. c. 5), allowing private citizens to prosecute cases and receive a quarter of the fines based on double the value of improperly sold goods. This provision was not repealed until the Common Informers Act 1951.[3]
