The question at once arose whether it was a function of the state or of the federal executive to see that the neutrality laws were properly enforced. In submitting the evidence of the operations of the British agents within the State of Louisiana Governor Heard declared it to be his opinion that it was the proper function of the federal and not of the state Government to enforce obedience to these laws; but, he concluded, "if such duty belongs to the State where the violations of such laws occur, I would not hesitate to act as the laws may warrant and in keeping with the dignity and responsibilities of statehood."[56] The Governor asked that he be informed immediately what, in the opinion of the federal authorities, were the powers and duties of the state governments in matters of this character. [Footnote 56: H.R., Doc. 568, 57 Cong., 1 Sess., p. 5.] Unquestionably it lay with the federal executive to see to it that the neutral obligations of all the States were properly observed. Certain duties rest upon the governors of the different States, but it is the function of the President to carry into effect the laws regulating neutral obligations as well as the provisions of all treaties with foreign powers as a part of the law of the land. This duty was pointed out by Secretary Randolph in a circular of April 16, 1795, to the governors of the different States during the war between France and England. He defined the duties of neutrality and concluded: "As often as a fleet, squadron or ship, of any belligerent nation shall clearly and unequivocally use the rivers, or other waters ... as a station in order to carry on hostile expeditions from thence, you will cause to be notified to the commander thereof that the President deems such conduct to be contrary to the rights of our neutrality.... A standing order to this effect may probably be advantageously placed in the hands of some confidential officer of the militia, and I must entreat you to instruct him to write by mail to this Department, immediately upon the happening of any case of the kind."[57] [Footnote 57: Moore, Digest of Int. Law, Vol. VII, p. 934-935.] It was the duty of the central Government to prevent as far as possible any abuse of the privileges which the laws of war allowed to the belligerents. "A Government is justly held responsible for the acts of its citizens," said Justice McLean of the United States Supreme Court, speaking of the Canadian insurrection of 1838. And he continued: "If this Government be unable or unwilling to restrain our citizens from acts of hostility against a friendly power, such power may hold this nation answerable and declare war against it."[58]
