3.3 Consent, Searches, Trespass & Unlawful Restraint
Key Takeaways
- A search by a private guard ordinarily requires valid consent or another specific lawful basis; mere suspicion or a uniform is not enough.
- Consent must be voluntary, given by someone with authority, and kept within the scope granted; it may be withdrawn.
- Property control supports credential checks and directions to leave, but continued refusal should be handled through post orders and police notification.
- Words, positioning, barriers, or retained property can restrain a person and create false-imprisonment risk even without handcuffs.
Search authority is not automatic
A private security guard does not gain a general search power from a Yellow Card, a uniform, or the client's ownership of property. A search needs a recognized lawful basis. In routine private-security work, the most common basis is voluntary consent connected to a disclosed condition of entry, such as an authorized bag inspection at a controlled venue. Emergency action or a narrow safety measure may involve other law, but a guard should not improvise those exceptions. Follow post orders and obtain police assistance when the basis is uncertain.
A request is not consent if the guard makes refusal impossible through threats, deceptive claims of police power, physical blocking, or retention of property. Valid consent should be:
- given voluntarily rather than through coercion;
- given by a person with actual or reasonably apparent authority over the place or item;
- specific enough that the guard understands what inspection is allowed; and
- limited to the scope and duration agreed to.
A person may withdraw consent. The guard should stop the consent-based search and apply the lawful site consequence—for example, deny entry to a restricted event under its announced conditions—rather than forcing the inspection. Refusing consent is not itself proof of a crime.
Conditions of entry and private property
Property owners may control access through neutral rules: employees display a badge, visitors sign in, deliveries use a designated entrance, or entrants agree to a posted screening process. A guard enforces those rules as the owner's agent, within policy and law. Explain the condition before the person enters whenever practical, apply it consistently, and offer the approved choice. If entry depends on inspection and the person declines, the usual result is no entry, not a compelled search.
A person who enters or remains without privilege after a lawful direction may create a trespass issue. The guard should communicate clearly: identify the restricted boundary, state that permission is denied or withdrawn, direct the person to leave by a safe route, summon a supervisor or police under post orders, and document the exact words and response. Ownership does not make unnecessary force or indefinite private custody reasonable.
How restraint happens
False imprisonment is unlawful confinement of a person against that person's will. Physical contact is not required. Consider the practical message received by the person:
| Guard action | Possible effect | Better control |
|---|---|---|
| Standing near an open exit while asking a question | Often a voluntary encounter | Say the person is free to leave if that is true |
| Blocking all exits with guards | Communicates that departure is forbidden | Block only for a supported lawful detention |
| Taking a driver's license to “run a check” | May prevent practical departure | Inspect and promptly return it under the access policy |
| Ordering “Stay here until I decide” | Express restraint | Identify the legal basis and call police promptly, or release |
| Asking a trespasser to leave | Direction enforcing property control | Provide a safe route and document refusal |
Handcuffs intensify restraint but are not the dividing line. The question is whether the person was intentionally confined without adequate legal authority. A guard should never use a back room, locked door, vehicle, threat, or displayed weapon simply to make questioning easier.
Scenario: the refused bag check
A venue posts that admission requires a bag inspection. Before entering, a visitor refuses. The guard should explain that inspection is a condition of entry, decline admission, and provide the exit route. The guard may not seize and open the bag merely because refusal appears suspicious. If the visitor enters through a prohibited opening, the guard should follow the trespass and emergency procedure, request departure, and summon assistance. Any observation of an actual weapon or immediate threat changes the safety facts and requires an emergency response, but it does not retroactively make a routine forced search proper.
Documentation and supervisor support
Record the rule communicated, the request made, the person's response, any words showing consent, the area or item inspected, whether consent was limited or withdrawn, and the outcome. For restraint, record the exact factual basis, start and end times, notifications, force if any, care provided, and transfer or release. Preserve video. A supervisor's order does not cure an unlawful act, but early consultation often prevents one.
Use a simple exam framework: authority, consent, scope, duration. Identify the authority before acting; obtain voluntary consent where needed; stay inside its scope; and end the encounter when the basis ends.
