He was a member of the
Liberal Party, and the member for
Lane Cove in the
New South Wales Legislative Assembly from 1975 to 1991. He served as Opposition Leader from 1981, elected as Leader shortly after that year's election, until 1983 when he was deposed by
Nick Greiner. The 1981 election had seen Dowd's predecessor Bruce McDonald defeated in the seat he was contesting and the Liberals winning the same number of seats as its Coalition partner, the National Country Party. The Liberal Party leader has always been the leader of the coalition due to the Liberal Party always having more seats than its coalition partner. The fact that the Liberal Party had won the same number of seats as the National Country Party meant that the now vacant Opposition leadership came under dispute between the new Liberal leader Dowd and National Country Party leader Leon Punch which ultimately went to Dowd. During Greiner's first term as Premier of New South Wales, Dowd was appointed
Attorney General, serving between 1988 and 1991 and also serving as Leader of the House during the same period. During his term as Attorney-General, important legal reforms in New South Wales were completed including establishment of the
Independent Commission Against Corruption and reforms of the criminal, tort and motor accident laws. Retiring from Parliament in 1991, Dowd was succeeded as Member for Lane Cove by future Opposition Leader
Kerry Chikarovski. He attempted a move to the federal arena when he sought preselection for the
1994 Warringah by-election following the retirement of Michael Mackellar but lost out to future Prime Minister Tony Abbott. ==Career as a jurist==
