Takeaway

In short, this case permits police to order a driver out of a vehicle during a lawful traffic stop without individualized suspicion, while requiring separate reasonable suspicion—such as a visible weapon-like bulge—for a protective frisk.

Background

Philadelphia officers stopped Harry Mimms because his automobile displayed an expired license plate. Following their routine practice during traffic stops, an officer directed Mimms to get out of the car and produce his license and registration. Once Mimms stepped out, the officer saw a large bulge beneath his jacket. Believing it might be a weapon, the officer frisked Mimms and found a loaded .38-caliber revolver in his waistband. Another occupant of the car also possessed a revolver.

Mimms was convicted of carrying a concealed deadly weapon and carrying a firearm without a license. The Supreme Court of Pennsylvania reversed, holding that the order requiring Mimms to leave the car was an unjustified Fourth Amendment seizure. Because that order led to the observation of the bulge and the frisk, the state court treated the revolver as the fruit of an unconstitutional intrusion. The Commonwealth sought Supreme Court review.

Issues

Issue #1

Whether the case remained justiciable after Mimms had completed the sentence imposed for his conviction.

Holding

Yes. The completed sentence did not make the case moot because the conviction could still produce collateral legal consequences.

Reasoning

The Court rejected Mimms's argument that the case became moot once he completed his prison sentence. A criminal conviction may continue to affect a person after release, including in later proceedings involving bail, sentencing, or probation.

Those possible collateral consequences gave both Mimms and the Commonwealth a continuing stake in the validity of the conviction. The Court therefore could review the federal constitutional question despite Mimms's completion of his sentence.

Issue #2

Whether, after a lawful traffic stop, an officer may order the driver to step out of the vehicle without particularized suspicion that the driver is dangerous.

Holding

Yes. An officer may order a driver out of a lawfully stopped vehicle because the minimal additional intrusion is reasonable when balanced against legitimate officer-safety concerns.

Reasoning

The initial traffic stop was unquestionably lawful because Mimms was driving with expired license tags. The Court therefore isolated the relevant Fourth Amendment question: not whether the stop was valid, but whether the additional command to exit the car was reasonable.

Officer safety is a legitimate and weighty governmental interest. A face-to-face encounter reduces the chance that a driver can make concealed movements inside the vehicle, and traffic stops can expose officers to assault or to danger from passing traffic.

The added burden on the driver was slight. Mimms was already lawfully detained for the traffic violation, and the choice was only between remaining seated in the car and standing beside it. The Court characterized that incremental intrusion as de minimis and held that it was outweighed by the safety interest.

Issue #3

Whether the officer could frisk Mimms after seeing a large bulge beneath his jacket.

Holding

Yes. The visible bulge gave the officer reasonable grounds under Terry v. Ohio to believe Mimms was armed and presently dangerous.

Reasoning

Under Terry, an officer who has lawfully stopped a person may conduct a limited protective search when specific facts would warrant a reasonably cautious officer in believing the person may be armed and dangerous.

Once Mimms left the car, the officer saw a large bulge under his jacket. That observation reasonably suggested that Mimms had a weapon, creating an immediate threat to officer safety.

Because the frisk was justified by the observed bulge rather than by the traffic violation alone, the revolver was lawfully recovered and should not have been suppressed.

Dissents

Justice Marshall

Reasoning

Justice Marshall joined Justice Stevens's dissent and stressed that the Court departed from Terry's limits on stop-and-frisk authority. Terry permitted a protective intrusion because the officer had specific grounds to suspect both criminal activity and the possibility of an armed robbery; by contrast, the officer here had no reason to suspect Mimms of any wrongdoing beyond an expired license plate.

In Marshall's view, the order to exit the car was unrelated in scope to the reason for the original stop. He also objected to the Court's summary resolution of an important constitutional issue on certiorari papers alone, particularly when the Pennsylvania courts could still rule for Mimms on independent state-law grounds.

Justice Stevens

Reasoning

Justice Stevens, joined by Justices Brennan and Marshall, argued that the Court abandoned the Fourth Amendment's traditional requirement of individualized justification. Terry required an officer to identify specific, articulable facts supporting the particular intrusion; the Court instead approved a blanket rule allowing officers to order every lawfully stopped driver from the car regardless of any individualized safety concern.

He questioned the empirical foundation for the Court's assertion that ordering a driver out of a car enhances officer safety. The study cited by the Court did not specifically address routine traffic stops or show that this practice reduces danger, and some police-training authorities advised officers to keep drivers inside their vehicles.

Stevens also disputed the claim that the intrusion is always trivial. The safety concerns and burdens of leaving a car may vary sharply with the circumstances, such as a nighttime stop, poor weather, health limitations, or the presence of children. Treating all traffic stops alike, he warned, permits arbitrary police discretion and potentially discriminatory enforcement.

Finally, Stevens objected to the Court's procedural choice to grant review and summarily reverse without full briefing and argument. The case created no pressing national conflict, Mimms had already served his sentence, and state-law grounds might still invalidate the conviction.
