“…There survives a single, but well-preserved and legible, set of records covering cases heard before one of the City's two sheriffs, John de Preston, for the period 1 July to 26 September 1320. 44 However, thanks to the quite Herculean efforts of Susanne Jenks, who studiously sought out references to Sheriffs' Court cases in various other document collections, including those of the Chancery, King's Bench, Common Pleas, the Exchequer, king's remembrancer's memoranda rolls and enrolment books, we have a substantial reconstruction of about 8-10 per cent of the Sheriffs' Court business of Michaelmas 1461 to Michaelmas 1462. 45 In particular, far and away the most common sources of references to Sheriffs' Court cases found by Jenks were Chancery and King's Bench corpus cum causa writs, issued to direct the addressee to present a specified imprisoned individual and the causes for his or her imprisonment to the issuing court -for our purpose, imprisonment in relation to a case or cases heard in the Sheriffs' Court.…”
