Wilbur v. United States Ex Rel. Krushnic

Background

A group of eight people located a tract called Spad No. 3 placer claim in Garfield County, Colorado, on October 1, 1919. The land contained oil shale and was one of six adjacent claims owned by the same people. The assessment year 1920 was extended to July 1, 1921, and some work was done on nearby group claims with the stated intention that it apply to the whole group. The claimant later acquired full interest in Spad No. 3, performed assessment work in 1921 and eventually had performed more than $500 in labor and improvements. He applied for a federal patent (federal title) in 1922, received a final receiver’s receipt, but the Commissioner and the Secretary of the Interior later declared the claim void for insufficient 1920 labor.

Reasoning

The core question was whether the Mineral Leasing Act of 1920 wiped out a locator’s right to keep a valid pre-Act claim by resuming work after missing a yearly assessment. The Court explained that a perfected mining claim is property and that resuming work after a lapse restores the claim’s status as if no default had occurred. The Court read the Leasing Act’s savings clause literally and held that resumption of work does maintain a valid claim. The Secretary’s contrary ruling was held to conflict with the plain language of the law, and the Court ordered that a writ of mandamus issue to require the patent application be decided on the merits, without being defeated by the temporary 1920 default.

Real world impact

Owners of valid mining claims that existed when the 1920 Leasing Act passed can preserve those claims by resuming work after a missed yearly labor requirement. The decision directs the Interior Department to decide patent applications on their substantive merits rather than canceling claims for a single missed assessment year. This ruling requires further administrative consideration of the claimant’s patent application consistent with the Court’s interpretation.
