N.D. Cent. Code § 6-03-61

Whenever a state banking association allows any person, copartnership, or corporation to become indebted to it, directly or indirectly, in excess of the amount, exclusive of interest, permitted by this title, the officer, director, or employee thereof willfully permitting or approving such loan is guilty of a class B misdemeanor, and in addition thereto, is liable personally to the association for the amount of such loan in excess of the statutory limit. Unauthorized loans, however, are not invalid.
