‘Parliamentary Perks’ as Constitutionally Protected Property?: Cunningham v Commonwealth

By Dr Lael Weis

How could the same constitutional provision that Darryl Kerrigan famously invoked to protect his ‘castle’ be relied upon by former Members of Parliament to protect ‘gratuitous’ — in the sense that they go above and beyond entitlements based on superannuation contributions — retirement benefits against any possible future reductions?

In this blog post I will briefly comment on the seemingly odd character of the constitutional challenge, explaining why Cunningham is not in fact that odd as far as s 51(xxxi) cases go. I will then offer a few remarks on what the commonplace character of challenges of this kind tells us about the broader challenges that confront the High Court’s jurisprudence in this area, and why the Court didn’t exactly tell the plaintiffs to ‘dream on’.
