Know Your Rights: Illegal Search and Seizure in California Criminal Cases

Understanding your Fourth Amendment rights against illegal search and seizure is crucial when facing criminal charges in California. Many criminal cases are won or lost based on whether police violated your constitutional rights during searches. As experienced criminal defense attorneys specializing in search and seizure violations, we’ve seen countless cases dismissed due to improper police conduct.

What is Illegal Search and Seizure?

Illegal search and seizure occurs when law enforcement searches your person, vehicle, or property without proper legal justification. The Fourth Amendment protects you from “unreasonable searches and seizures” and requires police to have either:

• Probable cause with a valid search warrant
• Reasonable suspicion for specific circumstances
• Your consent to search
• Exigent circumstances requiring immediate action

When Police Can Search Without a Warrant

Traffic Stops and Vehicle Searches

During a traffic stop, police can search your vehicle without a warrant if they have:

Probable Cause to Believe Vehicle Contains Evidence:

• Smell of marijuana or alcohol
• Visible contraband in plain view
• Suspicious behavior indicating criminal activity
• Reliable informant information

Search Incident to Arrest:

• If you’re arrested, police can search areas within your immediate reach
• This includes passenger compartments and containers
• Does not automatically include trunk or locked containers

Inventory Searches:

• When your vehicle is impounded
• Must follow standard department procedures
• Cannot be used as pretext for criminal investigation

Home Searches

Home searches receive the strongest Fourth Amendment protection. Police generally need a warrant unless:

Exigent Circumstances:

• Hot pursuit of fleeing suspect
• Preventing destruction of evidence
• Emergency aid situations
• Imminent danger to public safety

Consent Searches:

• Voluntary permission from resident
• Person must have authority to consent
• Can be revoked at any time
• Cannot be coerced or obtained through deception

Plain View Doctrine:

• Officer lawfully present
• Evidence immediately apparent as contraband
• Officer has lawful right of access

Stop and Frisk (Terry Stops)

Police can briefly detain and pat down individuals when they have:

Reasonable Suspicion of Criminal Activity:

• Specific, articulable facts
• More than mere hunch or intuition
• Based on officer training and experience
• Considering totality of circumstances

Officer Safety Concerns:

• Reasonable belief person is armed
• Limited to outer clothing pat-down
• Cannot manipulate objects to determine contents
• Must be brief and non-intrusive

Common Search and Seizure Violations

Pretextual Traffic Stops

Pretextual stops occur when police use minor traffic violations as excuse to investigate other crimes. While technically legal, they become problematic when:

• Stop duration exceeds reasonable time
• Questions unrelated to traffic violation
• Bringing drug dogs without reasonable suspicion
• Extending stop without additional reasonable suspicion

School Searches

School searches have lower standards than regular searches but still require:

• Reasonable suspicion of rule violation
• Search reasonably related to objectives
• Not excessively intrusive given age and nature of infraction
• School officials conducting search (not police)

Workplace Searches

Workplace searches depend on:

• Reasonable expectation of privacy
• Employment agreements and policies
• Public vs. private employment
• Purpose of search (investigation vs. work-related)

Border Searches

Border searches at ports of entry allow:

• Routine searches without suspicion
• More intrusive searches with reasonable suspicion
• Forensic device searches with reasonable suspicion
• Extended detention with reasonable suspicion

Technology and Digital Searches

Cell Phone Searches

Cell phone searches require warrants except for:

• Preventing imminent destruction of evidence
• Officer safety in immediate danger
• Hot pursuit situations
• True emergency circumstances

The Supreme Court’s Riley v. California decision provides strong protection for digital devices.

GPS Tracking

GPS tracking generally requires warrant for:

• Long-term tracking (over 28 days)
• Attaching devices to vehicles
• Real-time location monitoring
• Historical location data requests

Social Media and Email

Digital communications receive Fourth Amendment protection when:

• User has reasonable expectation of privacy
• Communications stored on private devices
• Accessing password-protected accounts
• Obtaining historical records from providers

Challenging Illegal Searches in Court

Suppression Motions (PC 1538.5)

Suppression motions seek to exclude illegally obtained evidence through:

Motion to Suppress Evidence:

• Filed before trial begins
• Challenges legality of search
• Burden on prosecution to justify search
• Judge decides admissibility

Exclusionary Rule:

• Illegally obtained evidence cannot be used
• Applies to derivative evidence (“fruit of poisonous tree”)
• Designed to deter police misconduct
• Protects constitutional rights

Burden of Proof

In suppression hearings:

Prosecution Must Prove:

• Search was constitutional
• Officers had proper justification
• Proper procedures were followed
• No constitutional violations occurred

Defense Can Challenge:

• Lack of probable cause
• Absence of reasonable suspicion
• Improper warrant procedures
• Constitutional violations

Exceptions That Don’t Apply

Common Misconceptions

“I Have Nothing to Hide”

• Constitutional rights exist regardless
• Information can be misinterpreted
• Innocent behavior may appear suspicious
• Rights protect everyone equally

“Police Said They’d Get Warrant Anyway”

• Police often cannot obtain warrant
• Making them get warrant protects rights
• Warrant requirement serves important purpose
• Don’t help police build case against you

“Refusing Consent Makes Me Look Guilty”

• Constitutional right to refuse
• Cannot be used as evidence of guilt
• Judges understand this principle
• Protecting rights is never suspicious

Practical Tips for Police Encounters

During Traffic Stops

Do:

• Keep hands visible
• Provide license, registration, insurance
• Be polite but exercise right to remain silent
• Ask “Am I free to leave?”

Don’t:

• Allow expansion of stop beyond traffic purpose

During Home Visits

Do:

• State clearly “I do not consent to search”

If Arrested

Do:

• Invoke right to remain silent clearly
