The Poarch Band of Creek Indians, a federally recognized tribe primarily located in Alabama, would be most directly affected. This bill clarifies their historical legal status under a key federal law and legally solidifies their existing land holdings. This impacts their ability to govern themselves, manage their resources, and pursue economic development with greater certainty.

Federal agencies, especially the Department of the Interior and the Bureau of Indian Affairs, would also be affected by this clarification as it defines the legal framework for their interactions and land management responsibilities with the Poarch Band. State and local governments bordering the Poarch Band's trust lands might also experience clarified jurisdictional boundaries, though the bill largely reaffirms existing arrangements.
