Pike v. Bruce Church, Inc., 397 U.S. 137 (1970), was a case in which the Supreme Court of the United States held that power of states to pass laws interfering with interstate commerce is limited when the law poses an undue burden on businesses.

[3] An Arizona statute required that Arizona-grown cantaloupes advertise their state of origin on each package.

[3] The company then brought a suit in federal court to stop Arizona from enforcing the order prohibiting Church from shipping the cantaloupes.

And the extent of the burden that will be tolerated will, of course, depend on the nature of the local interest involved, and on whether it could be promoted as well with a lesser impact on interstate activities.

[3]Applying this test to the Arizona statute, the court found it imposed too great of a burden to justify its benefits.
