Which of the following is NOT a ground for police or inspectors to apply to ARLA to suspend or cancel a license?

The correct choice highlights a fundamental aspect of licensing regulations and the grounds for police or inspectors to take action regarding a license. The grounds for suspension or cancellation of a license focus on the operational and safety standards of the premises and those holding the licenses, rather than personal conduct that may not directly relate to the management or operation of the licensed premises.

The concept of personal conduct pertains to an individual's behavior that may not necessarily affect compliance with licensing laws or the operation of the business itself. In contrast, the other options clearly indicate conditions that can directly impact the management of a licensed establishment, such as ensuring that the premises are not misused, having a suitable person in charge to oversee operations, and adherence to laws and operational conditions set forth in the licensing requirements.

This distinction emphasizes that while personal conduct is important in broader legal and ethical contexts, it does not serve as a legitimate ground for licensing authorities to initiate suspension or cancellation processes with respect to operational licenses held by establishments.
