Eventually the persistence of the tribe began to pay off. In 1968 the tribe won a case against the government with the Indian Claim Commission. The ruling stated that the lands had been taken illegally from the tribe in 1882, and that the tribe had the right to recover the lands by paying the government fair market value for the property. At a rate of 55 cents an acre, the value of the lands was set at slightly more than one million dollars. However, the tribe still fought for having the lands returned to them, without having to pay for them. The tribe found support from the Nixon administration, and began to lobby for passage of congressional bill S. 1296, which would return the lands to the tribe. Finally, in 1975, the U.S. Congress passed the Grand Canyon National Park Enlargement Act, which was signed into law by President Gerald Ford on January 4, 1975. Among other things, the Act returned of plateau and canyon lands to the Havasupai, which is what forms the reservation today.
