Said commissioner or any person authorized by him may summon and examine under oath any person who has knowledge of the affairs, transactions or circumstances being examined or investigated; and whoever without justifiable cause neglects upon due summons to appear and testify before the commissioner of insurance or his authorized representative, and whoever obstructs said commissioner or his representative in making examinations or investigations under this chapter, shall be punished as provided herein.

The commissioner may use the documents, materials or other information in the furtherance of any regulatory or legal action brought as part of the commissioner's official duties.
