ers, and prohibiting that of others. In the Constitution of
the United States, whatever else may be obscure, the clause granting
power to Congress over the Federal District may well defy
misconstruction. Art. 1, Sec. 8, Clause 18: "The Congress shall have
power to exercise exclusive legislation, _in all cases whatsoever_, over
such District." Congress may make laws for the District "in all
_cases_," not of all _kinds_. The grant respects the _subjects_ of
legislation, _not_ the moral nature of the laws. The law-making power
every where, is subject to _moral_ restrictions, whether limited by
constitutions or not. No legislature can authorize murder, nor make
honesty penal, nor virtue a crime, nor exact impossibilities. In these
and similar respects, the power of Congress is held in check by
principles existing in the nature of things, not imposed by the
Constitution, but presupposed and assumed by it. The power of Congress
over the District is restricted only by those principles that limit
ordinary legislation, and, in some respects, it has even wider scope.

In common with the legislatures of the States, Congress cannot
constitutionally pass ex post facto laws in criminal cases, nor suspend
the writ of habeas corpus, nor pass a bill of attainder, nor abridge the
freedom of speech and of the press, nor invade the right of the people
to be secure in their persons, houses, papers, and effects, nor enact
laws respecting an establishment of religion. These are general
limitations. Congress cannot do these things _any where_. The exact
import, therefore, of the clause "in all cases whatsoever," is, _on all
subjects within the appropriate sphere of legislation_. Some
legislatures are restrained by constitutions from the exercise of powers
strictly within the proper sphere of legislation. Congressional power
over the District has no such restraint. It traverses the whole field of
legitimate legislation. All the power which any legislature has within
its own jurisdiction, Congress holds over the District of Columbia.

It has been asserted that the clause in question respects merely police
regulations, and that its sole design was to enable Congress to protect
itself against popular tumults. But if the framers of the Constitution
aimed to provide for a _single_ case only, why did they provide for
"_all_ cases whatsoever?" Besides, this clause was opposed in many of
the state conventions, because the grant of power was not restric
