(b) Playgrounds or playground equipment constructed upon one, two and three-family residential real property are exempt from the requirements of this section. 4. Whenever the attorney general shall believe from evidence satisfactory to him that any person, firm, corporation or association or agent or employee thereof has violated any provision of this section, he may bring an action in the supreme court of the state of New York for a judgment enjoining the continuance of such violation and for a civil penalty of not more than one thousand dollars for each violation, except that the court may impose a civil penalty of not more than ten thousand dollars if the violation is knowing and willful. If it shall appear to the satisfaction of the court or justice that the defendant has violated any provision of this section, no proof shall be required that any person has been injured thereby nor that the defendant knowingly or intentionally violated such provision. In such action preliminary relief may be granted under article sixty-three of the civil practice law and rules. Before any violation of this section is sought to be enjoined, the attorney general shall be required to give the person against whom such proceeding is contemplated notice by certified mail and an opportunity to show in writing within five business days after receipt of notice why proceedings should not be instituted against him, unless the attorney general shall find, in any case in which he seeks preliminary relief, that to give such notice and opportunity is not in the public interest. * NB There are 3 § 399-dd's
