Section 17. (a) If, after a hearing pursuant to section fifteen, the commissioner finds that the insurance institution, insurance representative or insurance-support organization charged has engaged in conduct or practices in violation of this chapter, the commissioner shall put such findings in writing and shall issue and cause to be served upon such insurance institution, insurance representative or insurance-support organization a copy of such findings and an order requiring such insurance institution, insurance representative or insurance-support organization to cease and desist from the conduct or practices constituting a violation of this chapter.

(b) If, after a hearing pursuant to section fifteen, the commissioner determines that the insurance institution, insurance representative or insurance-support organization charged has not engaged in conduct or practices in violation of this chapter, the commissioner shall prepare a written report which sets forth findings of fact and conclusions of law. Such report shall be served upon the insurance institution, insurance representative or insurance-support organization charged and upon the person or persons, if any, whose rights under this chapter were allegedly violated.
