BAKER v. CARR.

Opinion of the Court.
case-by-case inquiry. Deciding whether a matter has
in any measure been committed by the Constitution to
another branch of government, or whether the action of
that branch exceeds whatever authority has been committed, is itself a delicate exercise in constitutional interpretation, and is a responsibility of this Court as ultimate
interpreter of the Constitution. To demonstrate this
requires no less than to analyze representative cases and
to infer from them the analytical threads that make up
the political question doctrine. We shall then show that
none of those threads catches this case.
Foreign relations: There are sweeping statements to
the effect that all questions touching foreign relations are
political questions. 1 Not only does resolution of such
issues frequently turn on standards that defy judicial
application, or involve the exercise of a discretion demonstrably committed to the executive or legislature; 82 but
many such questions uniquely demand single-voiced statement of the Government's views." Yet it is error to suppose that every case or controversy which touches foreign
relations lies beyond judicial cognizance. Our cases in
this field seem invariably to show a discriminating analysis
of the particular question posed, in terms of the history of
its management by the political branches, of its susceptibility to judicial handling in the light of its nature and
posture in the specific case, and of the possible conseE. g., "The conduct of the foreign relations of our Government
is committed by the Constitution to the Executive and Legislative'the political'-Departments of the Government, and the propriety
of what may be done in the exercise of this political power is not
subject to judicial inquiry or decision." Oetjen v. Central Leather
