Banning extremists is right — but Australia must get the law and oversight right

The High Court is being asked to adjudicate a vexed and necessary question: can the commonwealth ban a political grouping branded as a neo‑Nazi organisation, and if so, on what legal basis? The case over the designation of the White Australia party — the former National Socialist Network — as an illegal hate group exposes a hard tension in liberal democracies. We must be able to act decisively against violent, extremist movements, but we must also preserve the rule of law, constitutional limits and democratic safeguards. The home affairs minister declared the group illegal in May following advice from the Australian Security and Intelligence Organisation. That step reflected serious concerns about the group’s ideology and potential for harm. Yet lawyers arguing before the High Court say the ban is “authoritarian” and breaches the constitution, and contend that the commonwealth lacks power to proscribe a political party — a point tied back to the court’s 1951 ruling on attempts to outlaw the Communist Party. These are uncomfortable but crucial debates. The public instinct is simple: violent extremism and racist organising should have no place in our politics or streets. But the legal architecture for suppressing organisations must be robust, clearly delineated and capable of withstanding judicial scrutiny. Otherwise, we risk handing political opponents powerful tools to accuse governments of overreach — an outcome that serves neither security nor democracy. So what must happen? First, the government must be transparent about the basis for its decision. Secrecy around intelligence assessments breeds suspicion; transparency about legal reasoning and the evidentiary standard used to support proscription will help legitimate the action. Where operational or national‑security confidentiality is necessary, the government should explain what can be disclosed and why. Second, Parliament must accept its share of responsibility. Laws that curtail associational freedoms should be debated openly, with clear criteria set for what constitutes an illicit organisation, the avenues for appeal and periodic review mechanisms. A designation should not be an indefinite administrative fiat; independent review and sunset clauses create checks that protect civil liberties while keeping communities safe. Third, the state must invest in prevention as well as prohibition. Bans remove banners and platforms, but they do not alone extinguish the ideas or the social conditions that fuel them. Strategies to counter radicalisation, support communities at risk of recruitment and strengthen civic education are part of the same toolkit as legal proscription. Finally, courts must be allowed to do their job. The High Court’s role in testing executive action against constitutional boundaries is not an impediment to security; it is a safeguard that ensures measures taken in the name of safety are proportionate, lawful and sustainable. Governments that respect judicial scrutiny make it likelier that any restrictions on freedom will endure public confidence. Australians rightly expect their leaders to keep streets and institutions safe from militancy and hatred. But we should be equally insistent that the tools used are legally sound, transparent and accompanied by efforts to address root causes. A society that defends both security and the rule of law will be stronger for it.
