Sir John Wogan or John de Wogan, styled lord of Picton was a Cambro-Norman judge who served as Justiciar of Ireland from 1295 to 1313. There are several dubious theories about Wogan's ancestry, and uncertainty exists about his wives, sons, and other relations. He came from Picton in Pembrokeshire and was a vassal of William de Valence, 1st Earl of Pembroke. He came to have lands in Pembrokeshire, Somerset, Dorset, Devon, Wiltshire, and Oxfordshire. He may have represented de Valence at an Irish court case in 1275, and in 1280 he was steward of Wexford, Valence's Irish liberty. He was a justice in eyre in England in 1281–4, and returned to Ireland in 1285. In 1290 he was a referee with Hugh Cressingham in a dispute between Queen Eleanor and de Valence and his wife. He was on eyre again in the mid-1290s, sitting in the North of England.

John de Grauntsete or Grantsete (or John of Grantchester) (c. 1270 – c. 1350) was an English judge who lived in fourteenth-century Ireland. We know more about him than we do about any other contemporary Irish judge, and from the surviving information we can form some idea of the lifestyle of an Irish judge in his time. He sat in turn in each of the Irish Courts of common law, and uniquely he is known to have appeared in Court as an advocate even after he became a judge.
John de Ponz, also called John de Ponte, John Savan, or John of Bridgwater (c.1248–1307) was an English-born administrator, lawyer and judge in the reign of King Edward I. He served in the Royal Household in England for several years before moving to Ireland, where he practised in the Royal Courts as the King's Serjeant-at-law (Ireland). He later served as a justice in eyre, and then as a justice of the Court of Common Pleas (Ireland). He was a gifted lawyer, but as a judge was accused of acting unjustly. A case he heard in Kilkenny in 1302 can be seen as a precursor of the Kilkenny Witchcraft Trials of 1324, and involved several of the main actors in the Trials.

Hugh Canoun, or Hugh Canon was an English-born judge in early fourteenth-century Ireland. He was a justice of the Court of Common Pleas (Ireland) and served as Deputy Justiciar of Ireland.

On the other hand, his loyalty to the Crown during the Scottish Invasion of Ireland in 1315-18 was said to be extremely doubtful, although he was saved from disgrace by his influential connections. He was murdered by Andrew de Bermingham of Athenry in 1317/18, during the last months of the Bruce Invasion, in the course of a private feud, of which little is known.
