Court of Piepowders
（重定向自Piepowder）
A Court of Piepowders was a special tribunal in England organized by a borough on the occasion of a fair or market. These courts had unlimited jurisdiction over personal actions for events taking place in the market, including disputes between merchants, theft, and acts of violence. In the Middle Ages, there were many hundreds of such courts, and a small number continued to exist even into modern times. Sir William Blackstone's Commentaries on the Laws of England in 1768 described them as "the lowest, and at the same time the most expeditious, court of justice known to the law of England".
