Sedition Law and Legal Definition
Sedition the federal crime of advocacy of uprising or overthrow against the government or support for an enemy of the nation during time of war, by speeches, publications and organization. Sedition usually involves actually conspiring to disrupt the legal operation of the government and is beyond expression of an opinion or protesting government policy. Sedition is distinfuished from treason, which requires actual betrayal of the government, or "espionage."
The federal Sedition Act of 1918 states, in part, as follows:
"Whoever, when the United States is at war, shall willfully make or convey false reports or false statements with intent to interfere with the operation or success of the military or naval forces of the United States, or to promote the success of its enemies, or shall willfully make or convey false reports, or false statements, . . . or incite insubordination, disloyalty, mutiny, or refusal of duty, in the military or naval forces of the United States, or shall willfully obstruct . . . the recruiting or enlistment service of the United States, or . . . shall willfully utter, print, write, or publish any disloyal, profane, scurrilous, or abusive language about the form of government of the United States, or the Constitution of the United States, or the military or naval forces of the United States . . . or shall willfully display the flag of any foreign enemy, or shall willfully . . . urge, incite, or advocate any curtailment of production . . . or advocate, teach, defend, or suggest the doing of any of the acts or things in this section enumerated and whoever shall by word or act support or favor the cause of any country with which the United States is at war or by word or act oppose the cause of the United States therein, shall be punished by a fine of not more than $10,000 or imprisonment for not more than twenty years, or both...."
