Pauline Hanson could potentially succeed in having a key plank of the Racial Discrimination Act declared unconstitutional if she launches a High Court challenge, legal experts say. The Federal Court judgment was also hugely subjective, favouring the opinion of Senator Faruqi over Senator Hanson, she argued. Federal Court justices Melissa Perry, Geoffrey Kennett and Elizabeth Bennett’s July decision admitted Section 18C of the Racial Discrimination Act “casts a net”. Both Ms Clegg and University of Sydney constitutional law expert Professor Anne Twomey have also expressed concerns about Section 18C of the Racial Discrimination Act being potentially unconstitutional. Paul Keating’s Labor government added Section 18C to the 1975 Racial Discrimination Act in 1995.
