When an individual is arrested, it’s essential to understand both their rights and the legal boundaries set for law enforcement. In Australia, and many other common law jurisdictions, police powers during arrest are governed by strict legislation to ensure the rights of individuals are protected while enabling the police to perform their duties effectively. Whether you’re a law student, someone interested in civil rights, or just curious about legal procedures, knowing what the police can and cannot do is vital.

In this article, we’ll break down the key aspects of police powers during arrest, including when an arrest is lawful, what procedures must be followed, and what rights the arrested individual retains.

When Can Police Make an Arrest?

Police are legally permitted to arrest a person when:

1. They have a warrant issued by a court.
2. They suspect on reasonable grounds that a person has committed or is committing an offence.
3. They believe an arrest is necessary to prevent the continuation or repetition of an offence, protect public safety, or ensure the person appears before a court.

In most cases, police don’t need a warrant to make an arrest. However, there must be reasonable cause, and the arrest must be deemed necessary under relevant legislation such as the Law Enforcement (Powers and Responsibilities) Act 2002 (NSW) or its equivalents in other states and territories.

What Are Police Powers During Arrest?

1. Informing the Person of the Arrest

One of the core police powers during arrest is the obligation to inform the person of the reason for the arrest. This must be done clearly and promptly. Failing to do so may render the arrest unlawful.

2. Use of Reasonable Force

Police are permitted to use reasonable force to make an arrest or prevent an escape. However, the level of force must be proportionate to the circumstances. Excessive or unjustified force may lead to civil or criminal proceedings against the officers involved.

3. Search Upon Arrest

Once a person is arrested, police have the power to conduct a search for weapons, drugs, evidence, or anything that may pose a threat to safety. These searches must comply with specific guidelines, and in most cases, officers must explain the purpose of the search.

4. Seizure of Personal Property

Police may confiscate personal items from an arrested individual if they are considered potential evidence or pose a safety risk. This can include phones, weapons, or illicit substances.

Your Rights When Arrested

While police powers during arrest are broad, individuals still have important legal rights, including:

• The right to remain silent (except when providing name and address in certain situations).
• The right to be informed of the reason for the arrest.
• The right to contact a lawyer and, in some cases, a friend or relative.
• The right to an interpreter if English is not the person’s first language.

Children and young people are granted additional protections, including the presence of a parent, guardian, or independent adult during interviews.

What Happens After an Arrest?

After the arrest, the person is typically taken to a police station for processing and possible interrogation. Police have a limited time—generally four hours (extendable to 12 hours with judicial approval)—to question a suspect before they must be either charged or released.

If charges are laid, the individual may be:

• Released on bail
• Held in custody until a court appearance

Can You Challenge an Unlawful Arrest?

Yes. If a person believes they were unlawfully arrested, they may:

• File a complaint with the police oversight body in their state or territory.
• Seek legal advice to pursue civil action for false imprisonment or assault.
• Request the exclusion of evidence in court if obtained through an unlawful arrest.

Courts take police powers during arrest seriously and will assess whether an officer’s conduct adhered to the law.

Final Thoughts

Understanding police powers during arrest helps you stay informed about your rights and responsibilities. While police play a critical role in maintaining public safety, their authority is not without limits. Unlawful arrests, excessive use of force, and rights violations can have serious legal consequences.

If you or someone you know has experienced questionable treatment during an arrest, it’s crucial to seek legal advice immediately. Knowing your rights is the first step toward ensuring that justice is upheld.
