Which action can the commissioner NOT take regarding licensees?

The correct answer is that the commissioner cannot criminally charge a licensee for state law violations. This is because the power to bring criminal charges lies with law enforcement agencies or the district attorney, not with regulatory bodies like the commissioner. The role of the commissioner typically involves overseeing and regulating licensed individuals to ensure compliance with laws and regulations, but they do not have the authority to initiate criminal proceedings.

On the other hand, the commissioner can impose fines on licensees for various regulatory violations, as penalties for non-compliance are part of their enforcement powers. Revocation of a license is also within the commissioner's authority if a licensee is found to have violated laws or regulations seriously enough. Furthermore, conducting investigations is a fundamental part of the commissioner’s role, enabling them to assess compliance and enforce regulations effectively.
