Chapter XXVIII: Section II

I. The judicial power shall extend to all cases, in law and equity,
arising under this constitution, the laws of the United States, and
treaties made, or which shall be made, under their authority; to all
cases affecting ambassadors, other public ministers and consuls; to
all cases of admiralty and maritime jurisdiction; to controversies to
which the United States shall be a party; to controversies between two
or more states, between a state and citizens of another state, between
citizens of different states, between citizens of the same state
claiming lands under grants of different states, and between a state,
or the citizens thereof, and foreign states, citizens, or subjects.

II. In all cases affecting ambassadors, other public ministers, and
consuls, and those in which a state shall be a party, the supreme
court shall have original jurisdiction. In all other cases before
mentioned, the supreme court shall have appellate jurisdiction, both
as to law and fact, with such exceptions, and under such regulations,
as the congress shall make.

III. The trial of all crimes, except in cases of impeachment, shall be
by jury; and such trials shall be held in the state where the said
crime shall have been committed; but when not committed within any
state, the trial shall be at such a place or places as the congress
may, by law, have directed.

SECTION III.

I. Treason against the United States shall consist only in levying war
against them, or in adhering to their enemies, giving them aid and
comfort. No person shall be convicted of treason, unless on the
testimony of two witnesses to the same overt act, or on confession in
open court.

II. The congress shall have power to declare the punishment of
treason; but no attainder of treason shall work corruption of blood,
or forfeiture except during the life of the person attainted.
