What legal principle is affirmed through the issuance of a writ of habeas corpus?

The issuance of a writ of habeas corpus specifically affirms the right not to be detained without just cause. This legal principle serves as a critical safeguard against unlawful detention, allowing individuals to challenge the legality of their imprisonment. By filing a writ of habeas corpus, a detainee can seek judicial review of the reason for their detention, ensuring that they are not being held without appropriate legal justification or due process.

Habeas corpus is rooted in the fundamental legal notion that every individual has the right to know the reasons for their detention and to contest it before a court. This principle is paramount in protecting individual liberty and preventing arbitrary detention by the state or other entities. Thus, the correct answer highlights the essential nature of this legal remedy as a mechanism for upholding personal freedom against unlawful confinement.
