A court of equity sometimes makes a decree establishing a title. To enforce such a judgment, a writ may be issued, called a writ of assistance. It is directed to the sheriff and requires him to do some specific act, such as putting the defendant out of possession of certain lands and turning it over to the plaintiff.

It is, as appears from instances which have been given, possible that the execution of process from the courts may be defeated by violence which they cannot overcome. It is possible in fact though impossible in theory. As the sheriff can employ the posse comitatus, he ought always to have an overwhelming force at his command. But it is easier to "call spirits from the vasty deep" than to make them respond. Public feeling may be so strong in opposition to the service of the process that mob violence will be tolerated and even openly supported. An armed mob can only be effectually met by an armed force which is not a mob—that is, by disciplined soldiers.

The sheriff, if so opposed, may call upon the Governor of the State for military assistance. How efficient it will prove will, of course, depend on the discipline of the militia and the firmness of its commanding officers. It is seldom that it fails to restore order, if the men carry loaded guns and are directed to fire at the first outbreak of forcible resistance.

But the Governor may refuse to comply with the sheriff's request. In such case, the execution of the process of the court fails because of want, not of power, but of the will to exercise it on the part of those on whom that duty rests. In every government constituted by a distribution of the supreme authority between different departments, each of them must do its part loyally with respect to the others, or the whole scheme, for the time being, breaks down.

In the United States this danger is doubly great because of the interdependence of the general government and the particular States. Judicial process may issue from a State court against those who oppose its execution under claim of authority from the United States; or from a federal Court against those who oppose its execution under claim of authority from a State. Some instances of such conflicts of jurisdiction have been already mentioned.[Footnote: Chap. X.]

When the Supreme Court of the United States reverses a judgment of a State court, it can either[Footnote: U. S. Revised Statutes, Sec. 709.] itself render the judgment which the State court ought to have rendered, and issue execution, or remand the cause to it with directions that this be done. If the latter course be taken, the directions may be disobeyed. A Georgia court was guilty of this contumacy in the case of Worcester v. Georgia.[Footnote: 6 Peters' Reports, 515, 596.] If the former course be taken, the service of the execution may be resisted by the power of the State.

Worcester was illegally confined in the Georgia penitentiary. The sentence against him had been set aside and the indictment adjudged to furnish no ground of prosecution. But if the Supreme Court had rendered a judgment dismissing the prosecution, and given a writ to the marshal directing him to set Worcester at liberty, the officer would have found the prison doors shut in his face. Every prison is a fortress, so built as to prevent rescue from without as well as escape from within. To lay siege to one would be too great an enterprise for the marshal to undertake without military assistance. For this the President could have been called upon. But he might have refused it. If so, the judgment of the judicial department would have proved inoperative, simply because the officer charged with the duty of rendering it operative had declined to fulfil that duty.

The Supreme Court, in the Worcester case, probably had reason to believe that if it had directed a call on President Jackson for a military force it would have been refused. It is reported that the President, in private conversation, intimated as much. Possibly he might have been justified in the refusal. South Carolina was on the brink of war with the United States. Georgia was her next neighbor, and might have been induced to make common cause with her, if Jackson had battered down the doors of her penitentiary to release a man who, her courts insisted, had been properly convicted of a serious crime. A court can do nothing short of justice. The executive power, perhaps, may sometimes rightly act or decline to act from motives of national policy.

In one instance the armed forces of a State were actually engaged, under the authority of the legislature, in forcibly resisting the service of process from the federal courts. It was in 1809, when the marshal in Pennsylvania was opposed by a large body of the militia called out by order of the Governor for the purpose. Their commanding officer was subsequently arrested and convicted for the offense in the Circuit Court of the United States.[Footnote: Wharton's State Trials, 48; McMaster, "History of the People of the U. S.," V, 405; Willoughby, "The American Constitutional System," 41, 43.]

In 1859, the Governor of Ohio refused to honor a requisition from the Governor of Kentucky for the surrender of a fugitive from justice. The act charged was assisting a slave to escape. This was a crime in the State from which the man had fled, but not in the State where he had found refuge. The Supreme Court of the United States was asked by Kentucky to compel the surrender. It held that the Governor had violated his duty, but that the Constitution of the United States furnished no means for enforcing its performance by him.[Footnote: Kentucky v. Dennison, 24 Howard's Reports, 66, 109.] Under the shelter of this doctrine, a man indicted for murder in Kentucky has been for several recent years residing in safety in Indiana, because the Governor of that State has refused to comply with repeated requisitions for his surrender.
