In 1996, when the Liberals won office, he was appointed Attorney-General first as a member of the outer ministry and then as a member of Cabinet from October 1997.

In addition, Williams has been mooted as a contender for appointment as Chief Justice of the Family Court of Australia,^[7] a Justice of the Federal Court of Australia, the Supreme Court of Western Australia,^[8] or the Court of Appeal of Western Australia.^[9]
