 These statistics arise from the census conducted under the auspices of section 51(xi).Until its repeal by the 1967 referendum, section 127 prohibited the inclusion of Aboriginal people in section 24 determinations as including the Indigenous peoples could alter the distribution of seats between the states to the benefit of states with larger Aboriginal populations.Section 127, along with section 25 (allowing for race-based disqualification of voters by states) and the race power, have been described as racism built into Australia's constitutional DNA, and modifications to prevent lawful race-based discrimination have been proposed.
