S 550 Signed into law

Sponsored by Markwayne Mullin (R)

A bill to provide for the equitable settlement of certain Indian land disputes regarding land in Illinois, and for other purposes.

Lets the Miami Tribe of Oklahoma sue the federal government for a specific land claim dating to 1805.

Tradeoff

The Miami Tribe gains access to federal court to pursue one historical land claim without statute-of-limitations barriers. In exchange, the tribe forfeits all other current and future claims to land in Illinois.

What's in it

See official bill text

Negligible federal cost (between -$500,000 and $500,000) over 2025-2035.

The negligible federal cost is just the court administration fee; the bill's real effect is legal: it grants the Miami Tribe a pathway to sue the U.S. government for a specific historical land claim and permanently forecloses all other tribal claims to Illinois land.
