N.D. Cent. Code § 54-40.2-04
As a condition precedent to an agreement made under this chapter becoming effective, it must have the approval of the governor of North Dakota and the governing bodies of the tribes involved. If the agreement is a tax collection agreement between the tax commissioner and one or more tribes, the agreement also is subject to confirmation by a majority of members elected to the house of representatives and the senate and does not become effective until its legislative confirmation date or the effective date in the agreement, whichever is later. Each tax collection agreement presented for legislative confirmation must contain an expiration date not more than sixteen years after its effective date and the expiration date must be March thirty-first of an odd-numbered year. If the agreement obtains the approvals under this section and, if required, legislative confirmation under this section, it may be submitted to the secretary for approval.
