Conn. Gen. Stat. § 13b-203: (Formerly Sec. 16-54). When officers may be enjoined.

If, upon examination of any railroad or the affairs of any railroad company, the Commissioner of Transportation is of the opinion that such road is in such condition, or that the affairs of such company are so conducted, as to endanger public safety, or that the company has violated the law or refused to obey the directions of the commissioner or of the Superior Court or any judge thereof, he may, within one year after such examination, make application to any judge of said court for an injunction to restrain any person from exercising or attempting to exercise the duties of any officer in such company; and such judge may proceed thereon as the Superior Court may do on complaints for injunctions.
