(d) Tribal preemption authority over restricted fee tribal lands The laws of a federally recognized Indian tribe establishing a system of land tenure governing the use of land it holds, subject to a restriction imposed by the United States against alienation and taxation, shall preempt any provision of Federal law or regulation governing the use of such lands. Such tribal law shall be given preemptive effect only upon having been first published in the Federal Register. The Secretary of the Interior shall cause such tribal law to be published in the Federal Register not later than 120 days after receiving a copy of the tribal law from the Indian tribe. (e) Trust responsibility not diminished Nothing in this section shall be construed to diminish the Federal trust responsibility to any Indian tribe.
