We have to consider whether or not the breach of two fundamental human rights in New Zealand, which come under section 25, the minimum standards for criminal procedure, and section 26, the rule against retrospective punishment—whether we're doing something that's actually worth it. When there is no real evidence that what we're doing is protecting anyone at all, that becomes central to the integrity of this law. The rule of law, which it is our duty to uphold, is about transparency and the knowability of law to those that it impacts and affects. Retrospective legislation in every way breaches the rule of law.
