The first secure mentions of Basset are in royal
charters dating to around 1102, where he appears as a witness. He then appears as a judge in a royal dispute with the
sheriff of Yorkshire. probably close to 1110. In 1111, Basset took part in the
Michaelmas session of the
Exchequer, and he continued to take part in financial affairs and can be considered as an early
Baron of the Exchequer. Basset appears as a royal justice in 1116, serving in
Huntingdonshire. Basset was noted in the
Anglo-Saxon Chronicle entry for 1124 as hanging 44 thieves, during an
eyre in Leicestershire. Possibly, Basset's severity was part of an attempt to overawe the under-tenants of the Beaumont twins, one of whom,
Waleran, Count of Melun rebelled during 1124. During the period 1110–1127, Basset was one of the leading royal justices and was described by the medieval chronicler
Henry of Huntingdon as one of the "justices of all England". Huntingdon's implication is that Basset's scope was over all of England, not limited to his own locality. Basset seems to have spent most of his judicial and royal career in England, as he only is a witness on one royal document that was drawn up in Normandy. His most active period of royal service was from 1120 to 1130. An older view from historians was that Basset was
Chief Justiciar of England is not held by historians currently, nor can the idea that Basset was the head of justices or just the head of the itinerant justices during Henry's reign cannot be determined with any confidence either. It is clear that Basset was employed by the king extensively and probably that the nobleman worked mostly full-time for the king. Basset's rewards for his royal service included a number of manors. Basset was granted the manor of
Mixbury by the king after the family that held it at the time of Domesday Book died out and it
escheated to the king. Other lands held by Basset were probably royal rewards also. One was
Quiddenham, which had been held in 1086 by the crown. Another was
Stoney Stanton, originally held in 1086 by
Robert Despenser. ==Death and legacy==
