§ 89-v. Enforcement by attorney general. In addition to the other remedies provided, whenever there shall be a violation of this article, application may be made by the attorney general in the name of the people of the state of New York to a court or justice having jurisdiction by a special proceeding to issue an injunction, and upon notice to the defendant of not less than five days, to enjoin and restrain the continuance of such violations; and if it shall appear to the satisfaction of the court or justice that the defendant has, in fact, violated this article, an injunction may be issued by such court or justice, enjoining and restraining any further violation, without requiring proof that any person has, in fact, been injured or damaged thereby. In any such proceeding, the court may make allowances to the attorney general as provided in paragraph six of subdivision (a) of § 8303 of the civil practice law and rules. Whenever the court shall determine that a violation of this article has occurred, the court may impose a civil penalty of not more than one thousand dollars for each violation. Provided, however, a process server or agency may not be held liable for penalty in any action brought under this section for violation of this article, if the process server or agency shows by a preponderance of the evidence that the violation was not intentional and resulted from a bona fide error, notwithstanding the maintenance of procedures reasonably adopted to avoid any such error. Examples of a bona fide error include, but are not limited to, clerical calculation, computer malfunction and programming and printing errors. In connection with any such proposed application, the attorney general is authorized to take proof and make a determination of the relevant facts and to issue subpoenas in accordance with the civil practice law and rules.
