Gilcrease v. McCullough

Background

Thomas Gilcrease, a Creek Indian of one-eighth blood, received a surplus land allotment in 1902. On February 8, 1911—his twenty-first birthday by his claim—he signed an oil and gas lease to McCullough and Martin. He later sued in an Oklahoma state court to cancel the lease, arguing the enrolled roll showed an entry suggesting he was only nine years old on June 9, 1899, and therefore underage when he executed the lease. State courts ruled against him, and the case reached this Court on certiorari.

Reasoning

The central question was whether the official rolls, made “conclusive evidence” of age by §3 of the Act of May 27, 1908, entirely barred proof that a person was actually older than the roll’s entry suggested. The Court said the rolls are conclusive only as to what they expressly state. When an enrollment card records age merely in years (for example, “9”) and lacks months or days, that entry does not prevent introducing other evidence to fix the exact birthdate. The Court noted the enrollment form did not require precise birthdays, pointed out family entries that suggested the roll did not mean literal same-day births, and observed Department letters treating application date as an administrative convenience “for the purposes of the Government,” not a binding rule that Congress intended to make exclusive.

Real world impact

The decision means courts may consider outside evidence to determine whether an enrolled tribal member had reached majority when they signed land conveyances. That affects whether some leases or sales by allotment holders are upheld or set aside. The ruling affirms the state-court judgment while clarifying the limited, not absolute, conclusiveness of the rolls.
