Under what circumstances may a police officer seize liquor found during an investigation?

The correct answer involves circumstances where evidence is necessary to prove a contravention of the Act. This principle stems from the need for law enforcement to maintain public order and adhere to legal regulations surrounding the possession and distribution of liquor.

In situations where there is evidence that the liquor is linked to a violation of liquor laws, police officers are justified in seizing it as part of their investigation. This aligns with their duty to uphold the law and ensure compliance with regulations designed to promote safety and responsible consumption.

A search warrant is certainly a valid reason for seizing liquor, as it provides legal authority for a search; however, having evidence of a violation demonstrates a direct need for the seizure without necessarily requiring a warrant if the conditions of immediate necessity are met. In terms of public area considerations, while liquor may be observed in such spaces, seizing it still relies heavily on the evidence of wrongdoing. Consent from the owner also presents a legal basis for seizure, but it doesn’t equate to the broader necessity of proving an infraction, which is the core of why option B is the most fitting in the context of law enforcement authority and obligations.
