Kolender v. Lawson
The Court struck down a California law that let police arrest people who loitered on the streets and refused to give a "credible and reliable" identification when stopped, ruling the law was too vague to tell people what was required of them or to keep officers from enforcing it arbitrarily.
Because the law never defined what counted as sufficient identification, the Court found it handed police officers unchecked discretion to decide who had complied and who could be arrested, violating the Constitution's guarantee of fair notice and evenhanded law enforcement.
“An individual, whom police may think is suspicious but do not have probable cause to believe has committed a crime, is entitled to continue to walk the public streets "only at the whim of any police officer" who happens to stop that individual under § 647(e).”
Explaining why the identification law gave police too much unchecked discretion over pedestrians.
How it got here: A federal trial court found the law unconstitutional and enjoined it; the Ninth Circuit affirmed on vagueness and Fourth Amendment grounds, and the state officials appealed to the Supreme Court.
The Case in Depth
What happened
Edward Lawson, a Black man who often walked in his neighborhood at night, was stopped and questioned by California police about 15 times over roughly two years under a state law requiring loiterers to identify themselves credibly when an officer had reasonable suspicion. He was prosecuted twice and convicted once. He sued, arguing the law was unconstitutionally vague and used against him without proper legal grounds.
The question before the Court
Could California make it a crime for someone stopped by police on reasonable suspicion to refuse to give a "credible and reliable" identification?
Why it matters
People who are stopped by police on the street in California and similar jurisdictions can no longer be arrested simply for failing to satisfy an officer's personal judgment about what "reliable" identification looks like. The ruling curbs a tool many police departments used to detain and arrest people who had not committed any clearly defined crime, particularly affecting people frequently stopped without probable cause.
What changes now
The Supreme Court's affirmance is a final ruling on the merits, and the case is sent back to the lower courts for further proceedings consistent with the decision, including resolving Lawson's separate claim about a jury trial on damages against the officers. The California statute can no longer be enforced as written, though the state remains free to draft a more clearly defined identification requirement in the future.
What this does not decide
The Court decided the case only on vagueness grounds and expressly did not resolve whether the law also violated the Fourth Amendment's ban on unreasonable searches and seizures or the Fifth Amendment's protection against compelled self-incrimination, leaving those questions unaddressed.
Concurrences and dissents
Concurrence — Justice Brennan
Justice Brennan agreed the statute was unconstitutionally vague but would have gone further and held it violated the Fourth Amendment outright. He argued that requiring people to answer police questions or face arrest during a Terry stop, where officers only have reasonable suspicion rather than probable cause, exceeds what the Constitution allows regardless of how clearly the law is written.
Dissent — Justice White
Justice White, joined by Justice Rehnquist, argued the statute was not vague in all its applications and that a person who flatly refuses to give any information at all clearly violates the law without any need for police discretion. He contended the majority improperly blended vagueness and overbreadth analysis and would have reversed and let Lawson challenge the law only as applied to his own specific conduct.
How the Court got there
The legal reasoning, step by step
- The Court applied the void-for-vagueness doctrine, which requires criminal laws to define offenses clearly enough that ordinary people know what conduct is banned and that police cannot enforce them arbitrarily.
- The Court explained that the more important part of this doctrine is not fair warning to citizens but requiring lawmakers to give police minimal guidelines, so officers are not free to act on personal whim.
- Reviewing how California courts had defined the law's "credible and reliable" identification requirement, the Court found no real standard: officers themselves decided case by case whether an identification, or a suspect's explanation of his activities, was satisfactory.
- Because the statute let police officers decide moment to moment what would satisfy the identification requirement, the Court concluded it authorized exactly the kind of arbitrary, discretionary enforcement the vagueness doctrine forbids.
- The Court rejected the argument that ordinary need for crime-fighting tools could excuse this lack of clarity, holding that concerns about crime cannot justify a law that fails basic constitutional standards for definiteness.
