§ 7421. Removal of proceedings. Any time after commencement of a proceeding under this article, the superintendent may apply ex parte to the court or any justice thereof for an order changing the venue of and removing the proceeding to Albany county, or, in the discretion of the superintendent, to any other county of this state in which he deems that such proceeding may be most economically and efficiently conducted. Upon the filing of any such application, the court or any justice thereof shall direct the clerk of the county wherein such proceeding is pending to transmit all papers filed therein with such clerk to the clerk of the county to which such proceeding is removed. The proceeding shall thereafter be conducted in such other county as though it had been commenced in such county.
