Pauline Hanson, the veteran Australian senator and One Nation leader, has said she intends to challenge the nation's racial discrimination laws in the High Court, arguing they unduly restrict free speech. The move reflects Hanson's long-running campaign against what she and her supporters see as excessive legal curbs on public commentary about race, and it is likely to reignite debate in Australia over how to balance protection from discrimination with freedom of expression.

The full details of the specific case, legal grounds and timeline for the High Court challenge were not available in the source material provided. Hanson has previously clashed with anti-discrimination bodies and been the subject of complaints under Section 18C of the Racial Discrimination Act, which prohibits conduct likely to offend, insult, humiliate or intimidate people on the basis of race; her latest stance suggests she plans to use the courts to seek changes to how such provisions are applied or interpreted.
