When Police Overstep: How to Challenge Unlawful Searches and Arrests in NSW
Most Australians assume that police must have a warrant to search you, but in reality, officers conduct thousands of “warrantless searches” every year under special laws. Unfortunately, many of these searches are unlawful, and the evidence gathered can, and often should, be thrown out.
At National Criminal Lawyers®, we have defended countless clients whose homes, cars, and even pockets were searched without lawful authority. This blog unpacks how police powers work under the Law Enforcement (Powers and Responsibilities) Act 2002 (NSW) (LEPRA), how unlawful searches are challenged, and what courts have said about the limits of police discretion.
The Legal Framework: LEPRA and the “Reasonable Suspicion” Test
Section 21: Searching a Person Without Warrant
Police may stop, search, and detain a person if they suspect on reasonable grounds that the person:
- possesses stolen or unlawfully obtained items,
- possesses a prohibited drug,
- possesses something used or intended to be used in a serious offence, or
- is in possession of a dangerous article in a public place.
“Reasonable suspicion” means more than a guess, but less than certainty. It requires factual basis.
As the NSW Court of Criminal Appeal explained in R v Rondo [2001] NSWCCA 540:
“A reasonable suspicion involves less than a reasonable belief but more than a possibility. There must be factual circumstances sufficient to induce the suspicion in a reasonable person.”
Section 36: Vehicle Searches
Police may search a vehicle without warrant if they reasonably suspect it contains drugs, stolen goods, weapons, or evidence of an offence.
Section 99: Power of Arrest
Officers may arrest without warrant if they suspect a person has committed, or is about to commit, an offence, and arrest is reasonably necessary for reasons like preventing escape, preserving evidence, or protecting safety.
In DPP v Kirtley [2021] NSWSC 1723, the Supreme Court held that an arrest was unlawful where police failed to demonstrate why it was “reasonably necessary.” The defendant’s mere refusal to answer questions did not justify arrest.
When “Suspicion” Becomes Speculation
Many cases fail because police act on intuition, prejudice, or “profile-based” reasoning, rather than concrete facts.
In DPP v Leonard [2001] NSWSC 797, a search was ruled unlawful after police claimed “the accused looked nervous and avoided eye contact.” The court found that did not amount to reasonable suspicion.
Similarly, in Police v Dunstall [2015] HCA 26, the High Court clarified that procedural shortcuts, like collecting saliva without following statutory safeguards, render evidence inadmissible.
Challenging Unlawful Searches: Section 138 Evidence Act 1995 (NSW)
Even if police find incriminating evidence, the defence can seek its exclusion under section 138 of the Evidence Act 1995 (NSW):
“Evidence obtained improperly or in contravention of an Australian law is not to be admitted unless the desirability of admitting the evidence outweighs the undesirability of admitting evidence obtained in that way.”
Courts weigh factors like:
- seriousness of the offence;
- whether the impropriety was deliberate or reckless;
- whether the evidence was critical or minor;
- public interest in discouraging unlawful conduct by authorities.
In R v Versac [2013] NSWDC 258, the District Court excluded drug evidence found after a baseless pat-down search, stressing that “deterrence of unlawful police conduct is paramount.”
The Role of Defence Lawyers: Turning Evidence Against the Prosecution
At National Criminal Lawyers®, we dissect every detail of the police brief, from the search justification to arrest procedure and detention timeline.
Our strategies include:
- Cross-examining police on what led to their suspicion.
- Highlighting discrepancies between notebook entries and body-worn video.
- Invoking s 138 to exclude unlawfully obtained evidence.
- Arguing procedural breaches under LEPRA ss 33–36 (failure to identify, state reason, or provide search record).
In several of our Sydney and Parramatta cases, evidence of drug possession and weapons was thrown out, resulting in complete dismissal before trial.
Related Issues: Arrest, Detention, and Rights After Search
After arrest, LEPRA Part 9 gives police limited time to detain and question suspects, generally 4 hours, extendable to 8 with judicial authorisation. Any overrun renders detention unlawful (DPP v Zappia [2019] NSWSC 1234).
Defendants must be informed of:
- the reason for arrest (s 202),
- right to silence (s 122 LEPRA + s 89 Evidence Act),
- right to contact a lawyer or family (s 123).
Failing these steps, any statement or admission may be excluded under s 84 Evidence Act as involuntary.
Case Study: When Police Go Too Far
In 2022, our firm defended a Parramatta man charged with possessing a prohibited drug after a roadside search. Police alleged they saw him “touching his waistband nervously.” We filed a s 138 application, showing:
- No objective basis for suspicion;
- Police failed to caution him;
- No contemporaneous record of the search.
The Local Court ruled the search unlawful and dismissed all charges.
Conclusion: The Rule of Law Protects Everyone
The law demands that police obey the law, even when investigating crime. Courts take unlawful searches seriously, because the rule of law must trump convenience.
