1. The exercise by this Court of the power conferred upon it to
issue writs of habeas corpus (2 U.S.C. §§ 377, 451) in
aid of its appellate jurisdiction is discretionary and, save in
exceptional circumstances, the Court does not exercise the power
where an adequate remedy may be had in a lower federal court or
where, if the relief sought is from a judgment of a state court,
the petitioner has not exhausted his remedies in the state courts.
P.
320 U. S. 219.
2. Refusal of the writ, without more, is not an adjudication on
the merits, and is to be taken as without prejudice to an
application to any other court for the relief sought. P.
320 U. S. 220.
Applications denied.
PER CURIAM.
The applications are severally denied.
In these cases, petitioners invoke the exercise of the
jurisdiction conferred on this Court by 28 U.S.C. sections 377,
Page 320 U. S. 220
451, to issue writs of habeas corpus in aid of its appellate
jurisdiction.
Cf. Ex parte Peru, 318 U.
S. 578,
318 U. S.
582-583. That jurisdiction is discretionary,
id, 318 U. S. 584;
Bowen v. Johnston, 306 U. S. 19,
306 U. S. 27,
and this Court does not, save in exceptional circumstances,
exercise it in cases where an adequate remedy may be had in a lower
federal court,
Ex parte Current, 314 U.S. 578;
Ex
parte Spaulding, 317 U.S. 593;
Ex parte Hawk, 318
U.S. 746, or, if the relief sought is from the judgment of a state
court, where the petitioner has not exhausted his remedies in the
state courts,
Mooney v. Holohan, 294 U.
S. 103,
294 U. S. 115;
Ex parte Botwinski, 314 U.S. 586;
Ex parte Davis,
317 U.S. 592;
318 U. S. 318 U.S.
412;
Ex parte Williams, 317 U.S. 604. Refusal of the writ,
without more is not an adjudication on the merits and is to be
taken as without prejudice to an application to any other court for
the relief sought.
