The Secretary shall have exclusive authority to approve or disapprove a plan submitted by an Indian tribe in accordance with section 3405 of this title.
If the Secretary approves a plan under paragraph (1), the Secretary shall authorize the transfer of program funds identified in the plan in accordance with section 3412 of this title.
If the Secretary denies the plan under paragraph (1), the Secretary shall provide to the Indian tribe a written notification of disapproval of the plan that contains a specific finding that clearly demonstrates, or that is supported by a controlling legal authority, that the plan does not meet the requirements described in section 3405 of this title.
If a plan is denied under paragraph (3) solely on the basis that a request for a waiver that is part of the plan has not been approved (or is subject to dispute resolution) under section 3406 of this title, the Secretary shall, upon a request from the tribe, grant partial approval for those portions of the plan not affected by the request for a waiver.
With respect to a plan described in subparagraph (A), on resolution of the request for a waiver under section 3406 of this title, the Secretary shall, on a request from the tribe, approve the plan or amended plan not later than 90 days after the date on which the Secretary receives the request.
Notwithstanding any other provision of law, the Secretary may extend or otherwise alter the 90-day period identified in subsection (b)(1) for not more than 90 additional days, if, before the expiration of the period, the Secretary obtains the express written consent of the Indian tribe.
The district courts of the United States shall have original jurisdiction of a civil action against the appropriate Secretary arising under this section.
An Indian tribe may bring a civil action under this paragraph without regard to whether the Indian tribe had a hearing or filed an appeal under paragraph (1).
In an action brought under this paragraph, the court may order appropriate relief (including injunctive relief to reverse a denial of a plan under this section or to compel an officer or employee of the United States, or any agency thereof, to perform a duty provided under this chapter or regulations promulgated thereunder) against any action by an officer or employee of the United States or any agency thereof contrary to this chapter or regulations promulgated thereunder.
