Early life and education
Hayne was born in Gympie, Queensland and attended Scotch College, Melbourne. He graduated with a Bachelor of Arts and Bachelor of Laws (Honours) from the University of Melbourne, during which time he resided at Ormond College. Hayne was Editor of the Melbourne University Law Review. He then graduated with a Bachelor of Civil Law from Exeter College, Oxford University. He was also a Rhodes Scholar.
He is the husband of another High Court Judge Michelle Gordon.
Kenneth Hayne joined the bench in 1992 when he was appointed as a judge of the Supreme Court of Victoria. From 7 June 1995 he sat on the Court of Appeal of the Supreme Court of Victoria, which is the highest court in the Australian State of Victoria.
Hayne was appointed as a Justice of the High Court in September 1997. He retired in 2015 upon reaching the mandatory retirement age of 70, in accordance with Section 72 of the Australian Constitution. He was replaced on the High Court by his wife, Federal Court judge Michelle Gordon.
Hayne has been described as being a part of a 'core' of judges during his time on the High Court, usually forming the majority, and often writing joint reasons with Justice William Gummow. One notable exception was Hayne's dissent in Thomas v Mowbray, where he joined Justice Michael Kirby in holding the Commonwealth's regime of interim control orders applied in respect of suspected terrorists to be unconstitutional. Another, more recent, example is Kuczborski v Queensland  HCA 46 in which Hayne J was the sole dissenter.
In December 2017 Hayne was appointed to head the Royal Commission into Misconduct in the Banking, Superannuation and Financial Services Industry. The inquiry received continual media coverage and the report was delivered on 1 February 2019.
