2. The limits and potential of habeas corpus
This chapter details how in the Habeas Corpus Act, Parliament took control of the law of detention and established a powerful check on executive authority. But the Act’s limitations quickly came to light, including geographic limitations and the ability of Parliament to circumvent the Act with bills of attainder. Parliament also created the concept of suspension, by which it passed legislation to displace the Act’s protections for a period of time. This chapter details the early suspensions, their legalization of extra-judicial detentions, and how on their lapsing the habeas privilege sprang back to life. The chapter also highlights the continuing importance of the common law writ in cases to which the Act did not apply, such as slave cases. In particular, as explored in the chapter, Somerset’s Case is an example of just how powerful the common law writ could be not just in protecting—but also expanding—liberty.
