(2) the production of documents, books and records;
as may appear necessary for the hearing of the petition.

(c) Upon a proper showing, the court may grant a permanent or preliminary injunction or temporary restraining order or may order rescission of any sales, tenders for sale, purchases or tenders for purchase of equity securities determined to be unlawful under this chapter or any regulation or order of the commissioner.
