Fiske v. Kansas, 274 U.S. 380 (1927), was a United States Supreme Court Case that was first argued May 3, 1926 and finally decided May 16, 1927.

[2][1][3]A Kansas statute defined "criminal syndicalism" as "the doctrine which advocates crime, physical violence, arson, destruction of property, sabotage, or other unlawful acts or methods, as a means of accomplishing or effecting industrial or political ends, or as a means of effecting industrial or political revolution, or for profit .

The law was applied by a state court and was charged if the accused in some fashion held these views and formed a group of followers with a similar intent.

[2][1][3] The federal question was whether the Syndicalism Act as applied in this case was repugnant to the due process clause of the Fourteenth Amendment.

Fiske claimed that his organization in no way sought to bring about industrial change by illegal or criminal means.
