The commission shall have power to:

1.    Investigate all methods and practices of public utilities or other persons, subject to the provisions of this title.

4.    Compel obedience to its lawful orders by proceedings of mandamus or injunction or other proper proceedings, in the name of the state, in any court having jurisdiction of the parties or of the subject matter.

5.    Hold hearings on good cause being shown therefor or on its own motion, and to provide notice thereof and to shorten the period for which notice must be given prior to hearing, when good cause exists for such action. Such notice, however, must be reasonable in view of the nature, scope, and importance of the hearing. Whenever it appears to the satisfaction of the commission that all of the interested parties have agreed concerning the matter at hand, or that no interested party has asked for a hearing, the commission may issue its order without a hearing.

The commission shall ascertain the costs and expenditures. The application fees received by the commission under chapter 49-05 must be deposited in a special account within the public service commission. All moneys deposited in the account are appropriated on a continuing basis to the commission to pay expenses incurred in the processing of cases in which application fees are required. The commission shall refund the portion of a fee collected under chapter 49-05 which exceeds the expenses incurred for processing the case for which the fee was paid.
