A device for obtaining the same end—the views of the judges in advance of the enactment of a law—in a different way, has been from the first quite common. This is for the legislature to ask them specially for their opinion as to the constitutionality of a bill before it is put upon its passage. An analogous practice has always obtained in England, and was followed in several of the colonies.

Some of our State Constitutions expressly authorize such proceedings. In the absence of such authority, the judges can properly decline to comply with the request. It always asks them to prejudge a question which may later come before them in court, and to prejudge it without hearing any of the parties whom it may affect injuriously.[Footnote: See the Reply of the Judges of the Supreme Court of the General Assembly, 33 Conn. Reports, 586.]

President Washington, in 1793, brought a matter of this kind before the justices of the Supreme Court of the United States. It was during the controversy with M. Genet, the French minister, as to his right to refit a captured English merchantman as a privateer at an American port, and then send her out for a cruise. By the advice of his Cabinet, the President asked the justices a series of questions comprehending all the subjects of difference as to the proper exposition of the provisions of our treaties with France under which her minister made claim. They replied that they deemed it improper to enter the field of politics by declaring their opinions on questions not growing out of some case actually before them.[Footnote: Marshall, "Life of Washington," V, 433, 441.] No further request of this kind has since been made by any of the political departments to a court of the United States, except such as have been addressed to the Court of Claims.

Idaho, in her Constitution (Art. V, Sec. 25), has sought to give the legislature the benefit of judicial advice at the opening of each session as to what laws it might be desirable to enact. The judges of her trial courts are annually to report to those of her Supreme Court such defects and omissions in the laws as their knowledge and experience may suggest, and the latter, after considering these suggestions, are then, within the next five months, to report to the Governor such defects and omissions, both in the Constitution and in the laws, as they may find to exist.

The duty of the judiciary, in the course of lawsuits, to compare a statute, the validity of which is called in question, with the Constitution, and by the decision indirectly to affect legislation, is treated of elsewhere.[Footnote: Chap. VII.]

The courts of the United States, in controversies involving matters affecting the foreign relations of the general government, acknowledge in a certain degree a dependence upon the executive department. If they have a treaty to construe, any construction of it as to the point in question already given by the State Department will be followed, unless plainly wrong. If it becomes material to determine whether a certain country is subject to a certain power, and the President of the United States has dealt with that question (as by recognizing or refusing to recognize a minister accredited to the United States), his action will be accepted as conclusive. His proceedings would have like weight if taken within the limits of his authority with respect to the government of one of the United States.[Footnote: Luther v. Borden, 7 Howard's Reports, 1.]

When questions of this nature arise in a lawsuit between private parties, the courts can, without notice to them, seek information by communicating directly with the Department of State. It will be given by a letter or certificate, and this will be received as a conclusive mode of proof or as aiding the court in taking judicial notice of historical facts.

So an official letter or certificate from the minister or consul of a foreign power can be received and used as evidence as to facts in controversy peculiarly within the knowledge of that government.[Footnote: Gernon v. Cochran, Bee's Reports, 209.]

In prize cases, which must all be brought before the District Court, an appeal is allowed directly to the Supreme Court of the United States, although the judgments of the District Court generally are reviewable only in an intermediate court. This secures a prompt decision by the highest judicial authority of a question which necessarily affects, in some degree, the foreign relations of the United States.

But there may be cases affecting a vessel claimed as a prize which are not brought to secure her forfeiture and so are not prize cases. They may even to a greater extent affect our relations to foreign governments. How far can the courts, in dealing with these, govern their action by that of the executive?
