Opinion of the Court.
become operative. The Three Friends, 166 U. S. 1, 63,
66. Still again, though it is the executive that determines a person's status as representative of a foreign government, Ex parte Hitz, 111 U. S. 766, the executive's
statements will be construed where necessary to determine
the court's jurisdiction, In re Baiz, 135 U. S. 403. Similar
judicial action in the absence of a recognizedly authoritative executive declaration occurs in cases involving the
immunity from seizure of vessels owned by friendly
foreign governments. Compare Ex parte Peru, 318 U. S.
578, with Mexico v. Hoffman, 324 U. S. 30, 34-35.
Dates of duration of hostilities: Though it has been
stated broadly that "the power which declared the necessity is the power to declare its cessation, and what the
cessation requires," Commercial Trust Co. v. Miller, 262
U. S. 51, 57, here too analysis reveals isolable reasons
for the presence of political questions, underlying this
Court's refusal to review the political departments'
determination of when or whether a war has ended.
Dominant is the need for finality in the political determination, for emergency's nature demands "A prompt
and unhesitating obedience," Martin v. Mott, 12 Wheat.
19, 30 (calling up of militia). Moreover, "the cessation of hostilities does not necessarily end the war
power. It was stated in Hamilton v. Kentucky Distilleries & W. Co., 251 U. S. 146, 161, that the war power
includes the power 'to remedy the evils which have arisen
from its rise and progress' and continues during that
emergency. Stewart v. Kahn, 11 Wall. 493, 507."
Fleming v. Mohawk Wrecking Co., 331 U. S. 111, 116.
But deference rests on reason, not habit. 8 The question
in a particular case may not seriously implicate considerations of finality--e. g., a public program of importance
