HOUSE AND OFFICE SEARCH
A search of private premises must be supported by lawful authority.
A warrant is the usual legal basis for entering and searching a private home or commercial premises. The precise authority, threshold and permitted scope depend on the statute invoked, the terms of the warrant and the circumstances in which it is executed.
Warrantless entry and search are exceptions. They require valid consent or a specific statutory power, and the Police must remain within the limits of that authority.
Can the Police Look at Your Phone?↗01 — ENTRY AND SEARCH WITH A WARRANT
The warrant defines the lawful purpose and boundaries of the operation.
Source of authority
A Magistrate may issue a search warrant under section 50(7) of the Police Force Ordinance (Cap. 232). Further warrant powers arise under legislation directed to particular investigations, including the Dangerous Drugs Ordinance (Cap. 134). The statutory power used determines the permitted purpose and scope of the search.
Requirements
The application is supported by information on oath. Under section 50(7), the Magistrate must be satisfied that there is reasonable cause to suspect that a document or other item likely to be of value to the investigation of an offence is in the identified building, vessel or place.
Scope of the warrant
A warrant may authorise entry, including forcible entry where necessary, and the search and seizure of evidential documents and items. Depending on its wording and statutory basis, this may include computers, digital storage and other property of evidential value.
02 — ENTRY AND SEARCH WITHOUT A WARRANT
Search without a warrant can only be exercised under certain circumstances
Police may dispense with a warrant only where the occupier gives valid consent or where legislation expressly authorises entry and search in the circumstances.
ENTRY UNDER STATUTORY EXCEPTIONS
Pursuit and apprehension
Under sections 50(3) and 50(4) of the Police Force Ordinance, where an officer has reason to believe that a person to be arrested has entered or is in a place, the occupier must allow entry and reasonable facilities for the search. If entry cannot be obtained, forcible entry is permitted in the circumstances specified by section 50(4), including an urgent case in which a warrant could be issued but delay would give the person an opportunity to escape.
Search following arrest
Section 50(6) permits an officer who has apprehended a person to search for and take possession of a document, article or chattel found on that person, or in or about the place of apprehension, where the officer reasonably suspects it to be of value to the investigation. The power is tied to the arrest and the investigation; it is not a general authority to search an entire home or office.
National security investigations
The Implementation Rules for Article 43 of the Hong Kong National Security Law provide an exceptional power to search a place without a warrant where obtaining one is not reasonably practicable and the evidence may be removed, tampered with or destroyed. The search must be authorised by a police officer not below the rank of Assistant Commissioner of Police. The applicable legislation and current rules should always be checked in the individual case.
Customs and Excise inspections
Under statutory frameworks like the Import and Export Ordinance (Cap. 60) and the Customs and Excise Service Ordinance (Cap. 342), Customs and Excise officers are granted extensive powers to enter and search commercial premises without a search warrant. C&E officers have the legal authority to enter business offices, warehouses, factories, and the premises of importers, exporters, or manufacturers at any time without a warrant to conduct inspections. The law protects private residential homes, meaning Customs officers generally cannot enter domestic premises without a judicial search warrant.
03 — OCCUPIER'S RIGHTS DURING A SEARCH
A lawful search should not be obstructed, but an occupier does not surrender the right to remain silent, obtain legal advice or assert legal professional privilege. These safeguards should be raised clearly and as early as possible with the officer in charge.
Right to remain silent
An occupier is not generally required to answer investigative questions, explain documents or provide a statement merely because a search is taking place. The occupier may state that they wish to exercise the right to remain silent and obtain legal advice.
Right to legal advice
The occupier may contact a solicitor and ask for legal advice while the search is in progress. The solicitor can examine the warrant or asserted statutory authority, communicate with the officer in charge and help preserve an accurate record. Officers executing a lawful search may not be required to delay the operation until the solicitor arrives.
Legally privileged material
Confidential communications made for the purpose of obtaining or giving legal advice, and material created for litigation, may be protected by legal professional privilege. The occupier should identify any potentially privileged documents, devices or data immediately and request that they be segregated, sealed and not examined by the investigating team pending an agreed independent review procedure or a court's determination.
Warrant, scope and search record
The occupier may ask to see the warrant or other authority relied upon and should note its stated premises, purpose and scope. A contemporaneous record should be kept of the officers present, the areas searched, objections or privilege claims made and all property removed. The occupier should request a copy of the warrant and an inventory or receipt for seized items where available.
03 — WHY “FRUIT OF THE POISONOUS TREE” DOES NOT AUTOMATICALLY APPLY
Hong Kong does not apply the United States doctrine as an automatic exclusionary rule.
In United States constitutional law, the “fruit of the poisonous tree” doctrine may exclude evidence derived from an earlier unlawful search or other constitutional violation. Hong Kong takes a different approach: admissibility turns principally on relevance, the applicable evidential rule and the court's duty to secure a fair trial.
Relevance is the starting point
The general common-law position is that relevant real evidence is not automatically inadmissible merely because it was obtained unlawfully or improperly. Confessions and compelled testimony engage additional and distinct rules.
Fair-trial and constitutional discretion
The absence of automatic exclusion does not make the manner of obtaining evidence irrelevant. A court may exclude evidence where admission would render the trial unfair, and may consider the nature of any breach, its effect on protected rights, the reliability and probative value of the evidence, prejudice to the accused and the integrity of the criminal justice process.
A v Commissioner of ICAC
A v Commissioner of the Independent Commission Against Corruption (2012) 15 HKCFAR 362 concerned information compelled under the Prevention of Bribery Ordinance and the privilege against self-incrimination. It illustrates that the permitted direct and derivative use of compelled material requires close legal analysis, but it is not a general authority governing every unlawful premises search.
Other remedies remain available
An unlawful entry or search may expose the officers or public authority to civil proceedings, judicial review, complaints or disciplinary consequences. Those remedies are separate from the criminal court's decision on admissibility.
HOW MCS CAN ASSIST
Advice during a premises search.
MCS is often instructed to attend premises where a search warrant is executed. We can examine the warrant or asserted statutory authority, advise the occupier and staff during the search, communicate with the officers in charge, monitor the stated scope of the operation and keep a record of seized items. We can also advise on privilege, digital material, requests for return of property, the lawfulness of the search and the admissibility or use of any material obtained.
