THIS case was brought up from the Supreme Court of the State of Illinois, by a writ of error issued under the 25th section of the Judiciary Act.

The section of the law of Illinois, under which Eels was indicted in 1842, and the facts in the case are set forth in the opinion of the court, and need not be repeated. The court before which he was tried, fined him four hundred dollars, and the Supreme Court of Illinois affirmed the judgment. The case is reported in 4 Scammon's Rep. 498.

Moore v. Illinois (55 U.S. 13)

The arguments urged by the counsel for the plaintiff in error, in order to show that the law of Illinois was void, were,--

Moore v. Illinois (55 U.S. 13)

1. That the act of Congress, passed in 1793, was constitutional; that the power of legislating upon the subject of fugitive slaves, ought to be vested in Congress; that the act had been declared to be constitutional by the following authorities: 16 Peters, 620 et seq.; 9 Johns, 67; 12 Wendell, 311; 2 Pick. 11; 5 Sergeant & Rawle, 62; 2 Wheeler's Crim. Cases, 594.

2. That the power was vested exclusively in Congress, and if there was an omission to legislate, silence was as demonstrative of its will as express legislation. 5 Wheat. 1, 21, 22; 16 Pet. 617 et seq.

3. That admitting the power to be concurrent, its exercise by Congress supersedes all State legislation. 1 Kent, 380, 391; 1 Story, Com. on Con. § 437 to 443; 12 Wend. 316, 325; 1 Pet. Con. Rep. 429; 4 Id. 414-5; 2 Wheel. Crim. Cas. 594; 5 Wheat. 21, 24, 36, 70, 75; 14 Wend. 532-6; 16 Pet. 617-8.

4. The act of Congress of 1793, and the law of Illinois, conflict with each other.

5. Two laws legislating over the same offence, cannot exist at the same time.

6. If so, the law of Illinois must give way.

It was particularly pressed upon the court by Mr. Chase, that this court had decided, in the case of Prigg v. Pennsylvania, (16 Pet. 539,) that all State legislation upon the subject of fugitive slaves, was void, whether professing to be in aid of the legislation of Congress, or independent of it, was void; and he claimed the benefit of that decision.

The counsel for the defendant in error, commented on the various positions above mentioned; and the following extract from the brief, shows the principal ground relied upon to vindicate the State law.

The case just cited, (Houston v. Moore, 5 Wheaton,) leads directly to the question, What is the particular power exercised by the State in the present instance; whence derived, and what the design and mode of its operation? And it may be as well here to remark, that it is not alone in the light of an act in aid of the legislation of Congress, that this law is to be considered. The question before this court is one of power-of power in the State to legislate in the particular manner. If the power exists in the State, no matter from whence derived, the validity of the law cannot be questioned.

It is now contended that the power in question belongs to the States in virtue of their original and unsurrendered sovereignty; in virtue of those great conservative powers which all governments must have, exercise, and maintain for their own protection and preservation; powers which, in the language of Mr. Madison, (Federalist, No. 45,) 'extend to all the objects which, in the ordinary course of affairs, concern the lives, liberties, and properties of the people, and the internal order, improvement, and prosperity of the State.'

In the City of New York v. Miln, (11 Pet. 139,) the court say, 'that a State has the same undeniable, and unlimited jurisdiction over all persons and things within its territorial limits as any foreign nation, when that jurisdiction is not surrendered or restrained by the Constitution of the United States,' &c.
