 The court declared that Hill was not validly elected at the 1998 federal election . However , they did not declare the whole election invalid , acting on an earlier decision of the court , because although no effect could be given to voters ' preferences for Hill , their other preferences were not invalid , and those could be used to determine who should be elected in Hill 's stead . The court did not reach a definite decision about what action should be taken , remitting that question to a lower court . Eventually , Len Harris , the number two candidate on the One Nation ticket , was elected in Hill 's stead , taking up his seat on 1 July 1999 .
