The Principality's administration was overseen by the Prince of Wales's Council comprising between 8 and 15 councillors sitting in London or, later, Ludlow in Shropshire. The Council acted as the Principality's final Court of Appeal. By 1476, the Council, which became known as the Council of Wales and the Marches, began taking responsibility not only for the Principality itself but its authority was extended over the whole of Wales. The territory of the principality fell into two distinct areas: the lands under direct royal control and lands which Edward I had distributed by feudal grants. For lands under royal control, the administration, under the Statute of Rhuddlan, was divided into the two territories: North Wales based at Caernarfon and West Wales based at Carmarthen. The Statute organized the Principality into shire counties. Carmarthenshire and Cardiganshire were administered by the Justiciar of South Wales (or "of West Wales") at Carmarthen. In the North, the counties of Anglesey, Merionethshire, and Caernarfonshire were created under the control of Justiciar of North Wales and a provincial exchequer at Caernarfon, run by the Chamberlain of North Wales, who accounted for the revenues he collected to the Exchequer at Westminster. Under them were royal officials such as sheriffs, coroners, and bailiffs to collect taxes and administer justice. Another county, Flintshire, was created out of the lordships of Tegeingl, Hopedale and Maelor Saesneg, and was administered with the Palatinate of Cheshire by the Justiciar of Chester. The remainder of the principality comprised lands which Edward I had granted to supporters shortly after the completion of the conquest in 1284, and which, in practice, became Marcher lordships: for example, the lordship of Denbigh granted to the Earl of Lincoln and the lordship of Powys granted to Owain ap Gruffydd ap Gwenwynwyn, who became Owen de la Pole. These lands after 1301 were held as tenants-in-chief of the Principality of Wales, rather than from the Crown directly, but were, for all practical purposes, not part of the principality. Law The Statute of Rhuddlan also introduced English common law to the principality, albeit with some local variation. Criminal law became entirely based on common law: the Statute stated that "in thefts, larcenies, burnings, murders, manslaughters and manifest and notorious robberies – we will that they shall use the laws of England". However, Welsh law continued to be used in civil cases such as land inheritance, contracts, sureties and similar matters,
