John Blakeney (died 1438) was an Irish judge of the fifteenth century, who served three times as Chief Justice of the Common Pleas.
[1] It is unclear if he was a relative of James Blakeney, another senior official of the same generation who held office as Chancellor of the Exchequer of Ireland and as Chief Escheator.
[8] A judicial commission might deal with more mundane matters, as when Blakeney together with Sir Laurence Merbury, Lord Chancellor of Ireland and James Uriell, the former Chief Baron, inquired, in about 1421, into the proper line of inheritance to the lands of the Bathe family at Rathfeigh, County Meath.
[9] In 1432 he sat with his fellow Chief Justice Stephen de Bray and two other judges to hear a case of novel disseisin concerning lands in The Curragh, County Kildare.
[10] What seems to have been the last judicial commission appointing Blakeney as a member, dated November 1434, and which included most of the senior judges, was to inquire into all treasons committed in Dublin and the adjoining counties of the Pale.
