WINDOW ROCK, Ariz. (AP) – The Navajo Nation Council has approved a $554 million agreement to end litigation over the U.S. government’s alleged mismanagement of the tribe’s trust fund assets.

Officials at the tribal headquarters in Window Rock said Friday that the council voted 13-3 to approve the deal.

Execution of the agreement and payment to the tribe is contingent on final review and approval of the terms by Navajo Nation President Ben Shelly and the U.S. Departments of Justice, Interior and Treasury.

The tribe originally filed its lawsuit against the federal government in December 2006.

It alleges that the U.S. breached its fiduciary obligations under treaties, executive orders, federal statutes and regulations and contractual documents.

The suit also says the federal government failed to manage, invest and account for tribal trust funds and resources.
