During the passage of the Goods and Services Tax (GST) legislation in 1999, Stott Despoja, along with Andrew Bartlett, split from the party's other senators by opposing the package, which had been negotiated by Lees and prime minister John Howard. She said that she refused to break promises made by the party during the election. The party had gone to the election stating that they would work with whichever party formed government to improve their tax package. The Australian Democrats traditionally permitted parliamentary representatives to cast a conscience vote on any issue but, on this occasion, close numbers in the Senate placed greater pressure than usual on the dissenters.
