The police are subject to a range of different legal controls. They have a general duty to uphold the law, and breach of this duty can, in principle, be enforced by way of judicial review proceedings brought by members of the public. If, in the course of enforcing the law, the police detain, arrest, or assault an individual without lawful justification, they can be held liable for the torts of false imprisonment or trespass to the person, and they may also be held liable for the tort of misfeasance in public office if they act maliciously and unlawfully in the purported performance of their duties. as well as statutory torts specifically aimed at the police. The Human Rights Act 1998 provides further significant additions to the claims that can be brought against the police, and these are considered further in chapter 7. Claimants have also sought to establish that the police, like other public authorities, can be held liable for the tort of negligence, and it is such claims that are considered in this chapter.
