Wickard v. Filburn

Background

A small Ohio farmer planted more wheat than his official allotment under the 1938 Agricultural Adjustment Act and an amendment of May 26, 1941. He harvested excess wheat and refused to pay a newly increased penalty. He sued the Secretary of Agriculture and county and state agricultural committees to block enforcement, arguing the new penalty and rule were unconstitutional under the federal power to regulate interstate commerce and the Due Process Clause. A federal trial court blocked the higher penalty and lien, partly because it thought the Secretary’s public speech had invalidated a required farmer referendum.

Reasoning

The Court rejected the lower court’s view that the Secretary’s speech invalidated the referendum, finding no evidence the remarks misled or changed the vote. It then held that Congress could regulate and penalize excess wheat even if some of that wheat is consumed on the farm, because such home-grown wheat, taken together with many similar farms, substantially affects interstate markets and prices. The Court also rejected the farmer’s due process and retroactivity claims, noting the increased penalty became operative on threshing after the amendment, and that farmers had alternatives (storage, delivery to the Secretary, or loans) that reduced unfairness.

Real world impact

By reversing the injunction, the decision permits the Government to enforce the 1941 amendment’s higher penalties and lien provisions against farmers who market or process excess wheat beyond their quotas. The ruling affirms federal authority to regulate farm wheat that meaningfully influences interstate commerce and limits a court’s ability to block such national agricultural measures on the record presented.
