====Sales in open markets====

In the eighteenth century at the time of [[William Blackstone]], sales in an [[Market town|open market]] were an exception to the ''nemo dat'' principle in English law.<ref>William Blackstone (1753), ''[[Commentaries on the Laws of England]]'', Book 2, Chapter XXX "Of title by gift, grant, and contract": "But property may also in some cases be transferred by sale, though the vendor hath none at all in the goods; for it is expedient that the buyer, by taking proper precautions, may at all events be secure of his purchase; otherwise all commerce between man and man must soon be at an end. And therefore the general rule of law is, that all sales and contracts of any thing vendible, in fairs or markets overt, (that is, open,) shall not only be good between the parties, but also be binding on all those that have any right or property therein."</ref>

However, after the growth in the UK of [[car boot sales]] led to opportunities for rogues to "fence" stolen property,  the [[Sale of Goods (Amendment) Act 1994]]<ref>{{Cite legislation UK |type=act |year=1994 |chapter=32 |act=Sale of Goods (Amendment) Act 1994 |date=3 November 1994 |accessdate=5 May 2021 }}</ref> abolished the "[[Marché ouvert|market overt]]" exception to the ''nemo dat'' rule in 1995.
