	These utilitarian beliefs also underlay Williams's efforts as a law reformer, an activity in which he managed to play two roles at once. The first was the "establishment man". He devoted many hours over several decades to serving on a range of official committees, in particular the Criminal Law Revision Committee, of which he was a member from 1959 to 1980. In this capacity he shares the credit for a number of reports which led, among other things, to the decriminalisation of suicide in 1961 and the radical reform and codification of the law of theft in 1968.
