It is not disputed that the District is a part of "the United States," and that its residents are entitled to the privilege of trial by jury, whether in civil or criminal cases,[1355] and of presentment by a grand jury.[1356] Legislation which is restrictive of the rights of liberty and property in the District must find justification in facts adequate to support like legislation by a State in the exercise of its police power.[1357]
LEGISLATIVE POWER OVER DISTRICT OF COLUMBIA
Congress possesses over the District of Columbia the blended powers of a local and national legislature.[1358] Even when legislating for the District, Congress remains the legislature of the Union, with the result that it may give its enactments nation-wide operations so far as is "necessary and proper" in order to make them locally effective. As was pointed out in Cohens v. Virginia,[1359] if a felon escapes from the State in which the crime was committed, the government of such State cannot pursue him into another State and there apprehend him, "but must demand him from the executive power of that other State." On the other hand, a felon escaping from the District of Columbia or any other place subject to the exclusive power of Congress, may be apprehended by the National Government anywhere in the United States. "And the reason," declared Chief Justice Marshall, "is, that Congress is not a local legislature, but exercises this particular power, [of exclusive legislation], like all its other powers, in its high character, as the legislature of the Union."[1360]
TAXATION IN THE DISTRICT
Persons and property within the District of Columbia are subject to taxation by Congress under both the first and seventeenth clauses of this section. A general tax levied throughout the United States may be applied to the District of Columbia upon the same conditions as elsewhere;—e.g., if a direct tax, it must be levied in proportion to the census.[1361] But in laying taxes for District purposes only, "Congress, like any State legislature unrestricted by constitutional provisions, may its discretion wholly exempt certain classes of property from taxation, or may tax them at a lower rate than other property."[1362] It is no impediment to the exercise of either power that residents of the District lack the suffrage and have politically no voice in the expenditure of the money raised by taxation.[1363]
DELEGATION OF LEGISLATIVE POWER TO MUNICIPAL OFFICERS
Congress may delegate to municipal authorities legislative functions which are strictly local in character.[1364] It may confer upon them the power to improve or repair streets, to assess adjacent property therefor,[1365] and to regulate public markets.[1366] It may confirm assessments previously made by the District government without authority of law.[1367] But in Stoutenburgh v. Hennick,[1368] the Court held that Congress would not, and did not intend to, delegate to the District the power to impose a license tax on commercial agents who offered merchandise for sale by sample, since such a license amounted to a regulation of interstate commerce.
COURTS OF THE DISTRICT
In its capacity as a local legislature Congress may create courts for the District of Columbia and may confer upon them powers and duties which lie outside the judicial power vested in "constitutional" courts. On appeal from an order of the District Public Utilities Commission, a court for the District of Columbia may be empowered to modify valuations, rates and regulations established by the Commission and to make such orders as in its judgment the Commission should have made. But inasmuch as the issuance of such orders is a legislative as distinguished from a judicial function, the provision for an appeal from them to the Supreme Court was held unconstitutional.[1369]
