§ 476-b. Injunction to restrain defendant from unlawful practice of the law. In a civil action brought as prescribed in section four hundred seventy-six-a of this article, the final judgment in favor of the plaintiff shall perpetually restrain the defendant from the commission or continuance of the act complained of. A temporary restraining order to restrain the commission or continuance thereof may be granted upon proof, by affidavit, that the defendant has violated any of the provisions of such section. The provisions of statute or rule relating generally to injunctions as provisional remedies in actions apply to such a temporary restraining order and the proceedings thereupon, except that the plaintiff shall not be required to file any undertaking before the issuance of such temporary restraining order, shall not be liable for costs and shall not be liable for damages sustained by reason of the restraining order in cases where judgment is rendered in favor of the person, firm or corporation sought to be enjoined.
