Generally, police must obtain a search warrant before examining the digital contents of your phone in California. This protection usually applies even when the phone was seized during a lawful arrest.
A smartphone can contain text messages, photographs, emails, financial information, location history, social media activity, and other highly personal data. Because of the amount and sensitivity of this information, the United States Supreme Court has ruled that an arrest alone does not normally give police the authority to search through a phone.
However, there are important exceptions that may allow law enforcement to access a device without first obtaining a warrant.
Can Police Take My Phone During an Arrest?
Police may generally seize and secure a phone found during a lawful arrest. Seizing the physical device is different from searching its digital contents.
Officers may hold the phone while applying for a warrant and may take reasonable steps to prevent information from being remotely deleted. That does not automatically mean they can begin opening messages, reviewing photographs, or searching applications without additional legal authorization.
When Can Police Search a Phone Without a Warrant?
A warrantless phone search may be permitted in circumstances such as:
- Consent: You voluntarily give officers permission to search the device.
- An emergency: Officers reasonably believe immediate access is necessary to prevent death or serious physical injury.
- Certain supervision conditions: A person may be subject to an electronic-device search condition as part of parole, probation, mandatory supervision, postrelease community supervision, or pretrial release.
- A lost or stolen device: Officers may have limited authority to access information needed to identify or contact the owner.
- Another recognized legal exception: The specific facts surrounding the device and investigation may affect whether a search is considered lawful.
Consent is especially important. If you provide your passcode or agree to a search, it may become more difficult to challenge the search later. You have the right to clearly state that you do not consent and that you want to speak with an attorney. However, you should never physically resist officers, attempt to destroy information, or provide false information.
Whether police can legally require someone to unlock a phone using a passcode, fingerprint, or facial-recognition feature can involve additional constitutional questions. The answer may depend on the type of unlocking method, the wording of a court order, and the facts of the individual case.
Does a Warrant Allow Police to Search Everything?
Not necessarily. A search warrant should identify the device or accounts being searched and describe the categories of information investigators are authorized to obtain.
For example, a warrant may be limited by:
- The relevant time period
- The individuals or accounts involved
- The applications or services covered
- The types of messages, photographs, records, or other information sought
A warrant that is overly broad, unsupported by probable cause, or improperly executed may be challenged by a criminal defense attorney.
What Happens If Police Search My Phone Illegally?
When digital evidence is obtained through an unlawful search, the defense may file a motion asking the court to suppress it. If the motion is successful, prosecutors may be prohibited from using the illegally obtained messages, photographs, location information, or other data against you.
Suppression can significantly affect a criminal case, particularly when the prosecution depends heavily on digital evidence. However, an unlawful search does not automatically result in dismissal. The court must evaluate the circumstances of the search, the officers’ conduct, the warrant, and any exceptions claimed by the prosecution.
