At any time after the issuance of an order under Section 25219, any interested person (including, but not limited to, the issuer of the security and any broker-dealer who has been making a market in the security) may in writing request that the suspension of trading be rescinded. Upon the receipt of such a written request, the matter shall be set down for hearing to commence within 15 business days after such receipt unless the person making the request consents to a later date. After such hearing, which shall be conducted in accordance with the provisions of the Administrative Procedure Act, Chapter 5 (commencing with Section 11500) of Part 1 of Division 3 of Title 2 of the Government Code, and in connection with which the commissioner shall have all of the powers granted thereunder, the commissioner may order such suspension to be continued until modified or rescinded by further order of the commissioner if he finds that trading in the security will be unfair, unjust, or inequitable to investors or will tend to work a fraud upon the purchasers or sellers of such security. Otherwise, he shall rescind the suspension of trading and no further orders may be entered under Section 25219 with respect to the same security in the absence of changed circumstances justifying such order.
