What is the principle of "necessity" in police powers?

The principle of "necessity" in police powers refers to the idea that any actions taken by law enforcement must be necessary for a lawful purpose. This ensures that police interventions are appropriate and justifiable under the circumstances they face, reflecting a commitment to uphold the law while respecting individual rights.

When applying this principle, law enforcement must demonstrate that their actions are not only legal but also essential to achieve a specific lawful goal, such as preventing crime or ensuring public safety. This means that if a less intrusive alternative exists, officers should consider using that approach instead. This principle helps to prevent abuse of power and safeguards citizens against arbitrary actions.

In contrast, options that suggest actions should be for unlawful purposes, predetermined, or conducted in public do not align with the established legal framework governing police conduct. The emphasis on necessity serves to protect both the integrity of police work and the rights of individuals within the community.
