As for actual martial law, there was no declaration of martial law claimed
for the City of Washington, other than the proclamation of the President
which applied as well to Indiana, and, indeed, to the whole North.
We are justified, therefore, in saying, that the Supreme Court of the
United States, in this case of Milligan, pronounced the final condemnation
of the whole proceedings of the Military Commission which tried and
condemned Mary E. Surratt; declaring, with all the solemn force of a
determination of the highest judicial tribunal known to this nation, that
every one of its acts, from its creation by the President to its
transmission of its record of doom to the President, was in direct
contravention of the Constitution of the United States and absolutely null
and void.
That illustrious Court, speaking by Judge David Davis, thus enunciates the
law:
"The Constitution of the United States is a law for rulers and people,
equally in war and in peace, and covers with the shield of its
protection all classes of men, at all times, and under all
circumstances. No doctrine, involving more pernicious consequences,
was ever invented by the wit of man than that any of its provisions
can be suspended during any of the great exigencies of government.
Such a doctrine leads directly to anarchy or despotism."
"From what source did the Military Commission * * derive their
authority?"
"It is not pretended that the commission was a court ordained or
established by Congress."
"They cannot justify on the mandate of the President; because he is
controlled by law and has his appropriate sphere of duty, which is to
execute not to make the law; and there is no unwritten criminal code
to which resort may be had as a source of jurisdiction."
"The laws and usages of war can never be applied to citizens in states
which have upheld the authority of the government and where the courts
are open and their processes unobstructed. And no usage of war could
sanction a military trial there for any offence whatever of a citizen
in civil life, in nowise connected with the military service. Congress
could grant no such power; and to the honor of our national
legislature be it said it has never been provoked by the state of the
country even to attempt its exercise."
"All other persons," (_i. e._, all other than those in the military
and naval service) "citizens of states where the courts are open, if
charged with crime, are guaranteed the inestimable privilege of trial
by jury. This privilege is a vital principle, underlying the whole
administration of criminal justice; it is not held by sufferance, and
cannot be frittered away on any plea of state or political necessity."
"It is claimed that martial law covers with its broad mantle the
proceedings of this Military Commission."
