10-102.Who may file.

Section 10-102 states the basic entitlement behind the whole Article: every person imprisoned or otherwise restrained of liberty may apply for habeas corpus, in the manner Article X provides, to obtain relief from that imprisonment or restraint if it proves unlawful. The grant is broad on its face, reaching restraint generally rather than any single kind of custody.

Two limits sit inside that broad grant. First, the right runs "except as herein otherwise provided," a pointer to the categorical exclusions Section 10-123 later lists. Second, relief depends on the restraint proving unlawful in fact — the statute doesn't promise release on request, only a path to test the legality of the confinement.

The mechanics of how to apply come later in the Article, starting with the venue and complaint requirements in Section 10-103. Section 10-102 supplies the underlying right that those later, more procedural sections carry out.
