What authority does the department NOT have regarding unlicensed persons?

The authority that the department does not have regarding unlicensed persons is to issue injunctions directly. This is because issuing injunctions is a legal process that typically requires a court's involvement. The department can investigate complaints, seek court injunctions, and may have the authority to issue fines and reprimands to enforce regulations pertaining to licensed individuals and entities. However, the process for obtaining an injunction to halt an unlicensed activity must be conducted through the court system, which is overseen by a judge rather than by the department acting independently. Therefore, the correct answer reflects the limits of the department's authority in terms of direct legal action against unlicensed personnel.
