Oklahoma v. Texas
Headline: Boundary dispute over the 100th meridian: Court rejects competing historical surveys and orders an accurate new survey to mark the meridian, affecting territorial control between Oklahoma, Texas, and federal land claims.
Holding: The Court held that neither the Jones–Brown–Clark line nor the Kidder line was the established boundary; the true 100th meridian is the boundary and must be accurately located and marked by court-appointed surveyors.
- Requires a new official survey to fix the Oklahoma–Texas boundary along the 100th meridian.
- Affects land titles, patents, and pending land claims in the disputed strip.
- Clarifies which state will enforce laws and collect revenues in that area.
Summary
Background
The State of Oklahoma sued the State of Texas and the United States over a strip of land bounded by the Red River and the 100th meridian. Two rival on-the-ground surveys were in conflict: an 1859–1860 line run by Jones, Brown, and Clark, and a 1902 monument placed by Kidder. Congress and federal surveyors also made later measurements, and the area contains patents, school and university grants, and pending land claims. A prior suit decided which fork of the Red River marked the treaty line, but it did not fix the exact meridian line on the ground.
Reasoning
The Court addressed whether (1) the prior decree fixed the Jones–Brown–Clark line, (2) long recognition made that line the boundary, or (3) the Kidder monument established a line running north. The Court found the earlier decision did not fix the precise meridian location. It also found there was no long, uncontested acceptance of the Jones–Brown–Clark line, and that Congress never established a boundary running north from Kidder’s monument. For these reasons the Court concluded neither historic line was the established boundary.
Real world impact
The Court declared the boundary is the true 100th meridian from its intersection with the south bank of the South Fork north to the 36°30' parallel, and ordered court-appointed commissioner(s) to locate and mark that meridian accurately. That survey will determine which state controls the disputed strip, affect existing land patents and pending claims, and clarify which government enforces local laws. The parties were directed to submit a decree form within thirty days.
