Duby was elected to the inaugural ACT Legislative Assembly in 1989 general election on a platform that was critical of the decision by the Australian Government to replace direct administration of the Territory with self-government. The anti-self-government movement carried significant popular weight; an advisory referendum held in 1978 concluded that only 30.5 per cent of electors were in favour of self-government; and Duby plus two other members of his No Self Government Party and a representative of the Abolish Self-Government Coalition were elected to the inaugural 17-member Assembly. However, once elected, reversal of the move to self-government proved impractical. Duby resigned from the No Self-Government Party, along with Carmel Maher and David Prowse, to form the Independents Group on 3 December 1989. Duby left the Independents Group to found the Hare-Clark Independent Party on 19 November 1991.
