Ruddock remained on the backbenches, and stayed as a Hornsby Councillor until 1965. On 3 January 1975, with the ascendancy of
Tom Lewis as Premier of NSW he was appointed as
Assistant Treasurer of New South Wales and Minister for Revenue, an office which he held until 10 October 1975 when he was made Minister for Transport and Minister for Highways. He held these ministries until Lewis was replaced as Premier by
Eric Willis, who then reappointed him as Assistant Treasurer and Minister for Revenue on 23 January 1976. He held this office until the Coalition government lost the 1976 election on 14 May 1976. In his honour,
Parramatta City Council dedicated the "Max Ruddock Reserve" in
Winston Hills soon after his death. Philip went on to serve in the
Howard government as a Minister of the Crown, in particular as the
Attorney-General of Australia from 2003 to 2007. When Philip was elected as mayor of Hornsby in September 2017, he reflected on his father's time in office, particularly in Hornsby Shire: "His record and passion for Hornsby is a demonstration of his enormous affection for this area — not to mention the fact that he was a great role model to me". ==References==
