DPP v Wille

The case of the Director of Public Prosecutions (DPP) versus Wille was heard before the High Court of Australia. Wille was convicted for trespass on a nuclear power plant site during a protest against nuclear power. The central issue was whether Wille's actions, which involved entering the site to protest, constituted a lawful excuse for his trespass, given the right to peaceful protest. The court was required to determine the scope of the lawful excuse defence in the context of trespass and assess whether Wille's protest was peaceful and justified.

The court examined the principles of criminal trespass and the defence of lawful excuse. It considered whether Wille's entry onto the nuclear power plant site was justified as a peaceful protest under the common law. The court also assessed the balance between the right to protest and the need to protect critical infrastructure from unlawful intrusion. The central question was whether Wille's protest could be considered a lawful excuse for his trespass, given the potential risks associated with nuclear power plant operations.

The High Court held that Wille's trespass was not justified as a lawful excuse. The court found that while the right to peaceful protest is protected, it must be exercised in a manner that does not compromise the safety and security of critical infrastructure. The court emphasised the importance of maintaining public order and protecting sensitive areas from unlawful intrusion. The protest, which involved entering a highly secure nuclear power plant site, was deemed to go beyond the scope of what could be considered a lawful excuse. The court concluded that Wille's actions were not justified as a peaceful protest and affirmed his conviction for trespass.

The court's decision underscored the need for protestors to consider the potential risks and consequences of their actions, especially when targeting sensitive locations. The ruling clarified the limits of the lawful excuse defence in the context of trespass, particularly in relation to critical infrastructure. The High Court's decision emphasised the balance between the right to protest and the need to protect public safety and security.
