William Henry Moody,
Keizo v. Henry — Opinion of the Court
“ But no court may properly release a prisoner under conviction and sentence of another court, unless for want of jurisdiction of the cause or person, or for some other matter rendering its proceedings void. Where a court has jurisdiction, mere errors which have been committed in the course of the proceedings cannot be corrected upon a writ of habeas corpus, which may not, in this manner, usurp the functions of a writ of error. ”
