Neo-Nazi groups have lodged a constitutional challenge in Australia’s High Court as they seek to form a political party, according to reports from multiple outlets. The court action follows a recent government crackdown on extremism that has come into effect in the past days. The groups’ legal filing challenges the constitutionality of elements of the new regulatory or enforcement framework applied to extremist activity, while they continue efforts to register and operate as a political party.

All three reports describe the move as a response to the timing of the crackdown and the restrictions it imposes. They do not provide additional details in the excerpts about the specific grounds of the constitutional claim, the parties involved by name, or the procedural timeline for the case. The reporting is consistent in framing the High Court application as an attempt to overturn or limit the impact of the crackdown on their political party ambitions. The matter is at an early stage, with the High Court to determine whether and how the challenge proceeds.
