usual means and powers necessary to the attainment of that object are also granted. But the Constitution has left no occasion to resort to implication for these powers; it has made an express grant of them, in the 8th section of the 1st article, which ordains, "that Congress shall have power to make all laws which shall be necessary and proper for carrying into execution the foregoing powers, and all other powers vested by the Constitution in the government of the United States, or in any department or officer thereof."
This Constitution has established a Supreme Court of the United States, but has made no provision for its protection, even against such improper conduct in its presence, as might disturb its proceedings, unless expressed in the section before recited. But as no statute has been passed on this subject, this protection is, and has been for nine years past, uniformly found in the application of the principles and usages of the common law. The same protection may unquestionably be afforded by a statute passed in virtue of the before-mentioned section, as necessary and proper for carrying into execution the powers vested in that department. A construction of the different parts of the Constitution, perfectly just and fair, will, on analogous principles, extend protection and security, against the offences in question, to the other departments of government, in discharge of their respective trusts.
The President of the United States is bound by his oath "to preserve, protect, and defend, the Constitution;" and it is expressly made his duty "to take care that the laws be faithfully executed." But this would be impracticable by any created being, if there could be no legal restraint of those scandalous misrepresentations of his measures and motives which directly tend to rob him of the public confidence; and equally impotent would be every other public officer, if thus left to the mercy of the seditious.
It is holden to be a truth most clear, that the important trusts before enumerated cannot be discharged by the government to which they are committed, without the power to restrain seditious practices and unlawful combinations against itself, and to protect the officers thereof from abusive misrepresentations. Had the Constitution withheld this power, it would have made the government responsible for the effects, without any control over the causes which naturally produce them, and would have essentially failed of answering the great ends for which the people of the United States declare, in the first clause of that instrument, that they establish the same—viz., "to form a more perfect union, establish justice, insure domestic tranquility, provide for the common defence, promote the general welfare, and secure the blessings of liberty to ourselves and posterity."
Seditious practices and unlawful combinations against the federal government, or any officer thereof, in the performance of his duty, as well as licentiousness of speech and of the press, were punishable, on the principles of common law, in the courts of the United States, before the act in question was passed. This act, then, is an amelioration of that law in favor of the party accused, as it mitigates the punishment which that authorizes, and admits of any investigation of public men and measures which is regulated by truth. It is not intended to protect men in office, only as they are agents of the people. Its object is to afford legal security to public offices and trusts created for the safety and happiness of the people, and therefore the security derived from it is for the benefit of the people, and is their right.
