Explanation:

Habeas Corpus is a legal action or writ that demands that a person under arrest be brought to judgement in a court of law, to secure his release, unless there are legal reasons which justify their detention.

In many instances, the law enforcement authorities may arrest citizens and detain them for a long time without charging them. The Habeas Corpus prohibits this kind of incidence and abuse of power.
