In any proceeding for criminal contempt arising under title II, III, IV, V, VI, or VII of this Act, the accused, upon demand therefor, shall be entitled to a trial by jury, which shall conform as near as may be to the practice in criminal cases. Upon conviction, the accused shall not be fined more than $1,000 or imprisoned for more than six months.

This section shall not apply to contempts committed in the presence of the court, or so near thereto as to obstruct the administration of justice, nor to the misbehavior, misconduct, or disobedience of any officer of the court in respect to writs, orders, or process of the court. No person shall be convicted of criminal contempt hereunder unless the act or omission constituting such contempt shall have been intentional, as required in other cases of criminal contempt.

Nor shall anything herein be construed to deprive courts of their power, by civil contempt proceedings, without a jury, to secure compliance with or to prevent obstruction of, as distinguished from punishment for violations of, any lawful writ, process, order, rule, decree, or command of the court in accordance with the prevailing usages of law and equity, including the power of detention.

No person should be put twice in jeopardy under the laws of the United States for the same act or omission. For this reason, an acquittal or conviction in a prosecution for a specific crime under the laws of the United States shall bar a proceeding for criminal contempt, which is based upon the same act or omission and which arises under the provisions of this Act; and an acquittal or conviction in a proceeding for criminal contempt, which arises under the provisions of this Act, shall bar a prosecution for a specific crime under the laws of the United States based upon the same act or omission.

Whenever an action has been commenced in any court of the United States seeking relief from the denial of equal protection of the laws under the fourteenth amendment to the Constitution on account of race, color, religion, sex or national origin, the Attorney General for or in the name of the United States may intervene in such action upon timely application if the Attorney General certifies that the case is of general public importance. In such action the United States shall be entitled to the same relief as if it had instituted the action.

Nothing in this Act shall be construed to deny, impair, or otherwise affect any right or authority of the Attorney General or of the United States or any agency or officer thereof under existing law to institute or intervene in any action or proceeding.

Nothing contained in any title of this Act shall be construed as indicating an intent on the part of Congress to occupy the field in which any such title operates to the exclusion of State laws on the same subject matter, nor shall any provision of this Act be construed as invalidating any provision of State law unless such provision is inconsistent with any of the purposes of this Act, or any provision thereof.

There are hereby authorized to be appropriated such sums as are necessary to carry out the provisions of this Act.

If any provision of this Act or the application thereof to any person or circumstances is held invalid, the remainder of the Act and the application of the provision to other persons not similarly situated or to other circumstances shall not be affected thereby.
