The commissioner's order on a hearing must be issued within ________ after the hearing is concluded.

The correct answer is based on the regulations governing the activities of the insurance commissioner. After a hearing concludes, it is mandated that the commissioner must issue an order within 30 days. This timeframe ensures timely resolution of matters discussed during the hearing and promotes efficiency within the regulatory process.

By setting a 30-day limit, the law provides a clear time frame for both the involved parties and the commissioner, thus allowing for transparency and an expectation of prompt action. This requirement helps maintain the integrity of the regulatory system by preventing undue delays in communication and enforcement of decisions.
