Reporters in the King’s Bench in 1354 seem to have been interested in defining mayhem and refining the rules relating to proving and pleading in this area. There are three reports in the Seipp database.
Seipp 1354.043 is probably KB 27/376 m. 10 [AALT IMG 3179], Robert de Yakesle v. Thomas de Ribbeford (KB 1354T). In both roll and report, there is a request that the wound in question should be looked at by two London doctors, to see whether or not it amounts to mayhem. The Year Book makes it clear that this is at the defendant’s risk – he is putting himself entirely on this issue. This does seem to put quite a burden on the defence, and is worth thinking about with regard to the balance between accusers and accused. The facts of 1354.099ass also deal with medical evidence in a mayhem case, though with some more details, and suggesting a degree of recognition by the court of its own lack of expertise in terms of assessing the fresh wound. Might this be the same case?
Seipp 1354.044 looks to me like KB 27/376 m.10 (AALT IMG 2925), John, parson of the Church of Stowe v Hugh the Ironmonger of Daventry (KB, 1354T). since both cases involve injury to the finger next to the little finger. The Year Book suggests a querying by D of whether this could amount to mayhem, followed by a clear ruling that it could, and an alternative plea of self-defence. The Plea Roll, as one would expect, only records the self-defence plea actually relied upon. My immediate thoughts on seeing this pleading were that mayhem seems to have been a slightly ill-defined concept at this period, and that this is something of a contrast with all those specific penalties/ sums due in conpensation for different injuries which are listed in the Leges Henrici Primi.
