Can the Supreme Court grant a writ of habeas corpus of commitment, and does it extend to a prisoner committed by a court without competent jurisdiction?

is deemed to comprise every subsidiary question fairly included therein. Only the question set out in the petition, or fairly included therein, will be considered by the Court. 1. Can the Supreme Court grant a writ of habeas —iof^comm±tment? 2. Does it extend to a prisoner? 3. Is this a case where the writ should issue, where one is committed by a Court without competent jurisdict ion? and 4. By what Authority exactly am I committed and/or de tained???
