Tennessee Constitution
Article I - Declaration of Rights.
Section 19

That the printing press shall be free to every person to examine the proceedings of the Legislature; or of any branch or officer of the government, and no law shall ever be made to restrain the right thereof. The free communication of thoughts and opinions, is one of the invaluable rights of man and every citizen may freely speak, write, and print on any subject, being responsible for the abuse of that liberty. But in prosecutions for the publication of papers investigating the official conduct of officers, or men in public capacity, the truth thereof may be given in evidence; and in all indictments for libel, the jury shall have a right to determine the law and the facts, under the direction of the court, as in other criminal cases.
