 The new steward was the Earl of Oxford, but he was unable immediately to take control as the Durham Act of 1763 prevented honorary freeman from voting within a year of their creation; however, it transpired that Henry Lewis's patent as Steward had not been properly renewed on the accession of George III in 1760, so that all his more recent creations of freemen were invalid.This immediately undermined Thomas Lewis's majority, and at the 1768 election), although Thomas's son John was declared elected by the returning officer, the result was overturned on petition, the votes of the faultily-created freemen were disallowed, and his opponent Edward Lewis (no relation) was declared elected instead.By 1774, Oxford's newly created freemen were qualified to vote, but the returning officer (remaining loyal to Thomas Lewis) attempted to disallow the votes of all non-resident freemen.
