Searches & Seizures: Motor Vehicles

Focus on searches and seizures, especially related to motor vehicles and open fields.

Definition: The plain view doctrine is an exception to the warrant requirement for searches and seizures.
Key Points:
- Does not allow entry into private premises for seizure without a warrant.
- Law enforcement officials can make warrantless seizures of evidence in plain view if:
- The officer observes the object from a lawful vantage point.
- The incriminating nature of the object is immediately apparent.
- The officer can take control of the object without violating the Fourth Amendment.
Context for Seizure:
- An object may present itself during a search for other evidence.
- It can occur during stop and frisk, routine traffic stops, or valid police observations.
Legal Theory:
- Contraband left in open view, observed by officers lawfully positioned, does not violate privacy expectations.
- No search within the Fourth Amendment context as long as officers maintain lawful observance.
Case Reference:
- Coolidge v. New Hampshire (1971): Established requirements for valid plain view seizures:
- Observed evidence from a lawful position.
- Discovery must be unexpected.
- Incriminating nature must be obvious.
- Inadvertent discovery is crucial; if officers expected to find it, the seizure does not qualify under this doctrine.

Scenario: A police officer observes a car traveling 90 mph in a 45 mph zone. The car, with a flat tire, sparks upon contact with the road:
- Police stop the vehicle.
- The driver falls out; officer detects a strong odor of marijuana.
- Officer sees plastic baggies of marijuana in plain view.
Outcome: Appellate courts upheld the seizure based on plain view doctrine principles due to lawful observation and clear illegality.

Unique Aspects of Motor Vehicles:
- Motor vehicles can move out of jurisdiction quickly, complicating warrant acquisition.
- Expectation of privacy is lower in vehicles compared to homes/buildings.
- Extensive state regulation on motor vehicles.
General Rule: Still requires probable cause before a search.
Probable Cause Definition:
- Established through police observations, limited reports, or informants.
Case Reference:
- Carroll v. United States (1925): Police had probable cause to stop a vehicle suspected of transporting illegal liquor, allowing warrantless searches.
Fourth Amendment Interpretation:
- Literal reading suggests a warrant is needed, but Supreme Court permits warrantless vehicle searches under probable cause due to mobility issues.
- Warrantless seizure may conflict with Fourth Amendment, yet often deemed reasonable for immediate action given probable cause.

Case Reference:
- Chambers v. Maroney (1970): Upheld immediate warrantless search of a vehicle suspected in a robbery due to existing probable cause.
Considerations:
- Immobilization of a vehicle until a warrant is obtained is debatable; both immediate searches and immobilization are deemed reasonable under the Fourth Amendment given probable cause.

Situation:
- Police suspected a defendant of murder but had no access to the vehicle or exigent circumstances to justify an immediate search.
Ruling:
- Searches invalidated due to lack of a warrant; set precedent that stationary vehicles lacking movement may require a warrant.

Determining Lawful Search Extent:
- Scope depends on the nature of the object being searched for.
- Example: If searching for a stolen laptop, checking the trunk is appropriate; searching unlikely places like the ashtray would not be.
Drug Searches:
- If probable cause exists for drugs, almost any area in the car can be searched without being unreasonable.

Case Reference:
- Michigan v. Sitz (1990): Approved checkpoint stops to screen drivers for alcohol impairment, justified based on state's interest over minimal intrusion.

Scenario: Police conducts stops without individualized suspicion to combat drug trafficking.
Ruling: Found unconstitutional as it failed to meet Fourth Amendment standards focused solely on criminal interdiction without a specific purpose for stops.

Established that if an officer has reasonable suspicion of criminal activity, a limited search is permissible without probable cause.

Lawful Stops: If a traffic stop is lawful, evidence in plain view is seizable if its criminal nature is apparent.
Example Case:
- Officers stop a vehicle for a non-working taillight and observe a firearm in plain view; thus, allowed to seize the firearm as it led to a new crime by a felon.

Evolution of Jurisprudence:
- Historically convoluted, courts struggle to rationalize privacy expectations concerning containers in vehicles.
Case References:
- Carroll v. United States (1925): General vehicle search approval.
- United States v. Ross: Warrantless search of a car, trunk, and various containers allowed upon probable cause.
- Arkansas v. Sanders: Requiring a warrant to search luggage from the trunk, differing from previous rulings.
California v. Acevedo (1991):
- Established that police can search containers in vehicles without a warrant if they have probable cause to believe contraband is inside.

Key Takeaway: Searches of vehicles and containers therein must be justified under the Fourth Amendment based on probable cause, adapting to the context of mobility and privacy expectations in locations such as motor vehicles. Police possess considerable authority to conduct warrantless searches under specific circumstances without contravening constitutional rights.
