He was a member of
Gray's Inn, and on 16 June 1471 was appointed
Attorney General, with full power of deputing clerks and officers under him in courts of record. As Attorney General he conducted the impeachment of the
Duke of Clarence for treason. In Trinity term of 1478 he was made a
Serjeant-at-Law, and on 7 May 1481 was appointed
Chief Justice of the King's Bench, in succession to Sir
Thomas Billing, at a salary of 140 marks a year. This appointment was renewed at the ascension of each of the next three kings, and under
Henry VII, he was also a commissioner to decide the claims made to fill various offices at the coronation. In the first year of this reign, he successfully protested against the
king's practice of consulting the judges beforehand upon crown cases which they were subsequently to try. In June 1492, he was a commissioner to treat with the ambassadors of the
King of France. He died 8 September 1495, and was buried at
Sempringham. On 24 November of that year, Sir
