The provisions of sections 29-29-01 and 29-29-18 and rule 41 of the North Dakota Rules of Criminal Procedure, as to the service and return of a search warrant, and hearing, and return thereon to the district court, govern in cases of search warrants issued pursuant to the provisions of this chapter except that testimony of witnesses need not be reduced to writing. If the magistrate finds that the property seized is property of the kind described in the search warrant and that there is probable cause to believe that the grounds on which the search warrant was issued existed, the magistrate shall send the property so seized to the district court, together with the magistrate’s return. If the magistrate finds that there is not probable cause to believe that the grounds on which the search warrant was issued existed, the magistrate shall order the property returned to the person from whom it was taken.
