Lange v. California: A Key Supreme Court Case on the Fourth Amendment and Search and Seizure Laws

June 2, 2023

Lange v. California (2021) was a landmark decision by the Supreme Court of the United States that addressed the issue of warrantless searches by law enforcement officers. The case has important implications for the Fourth Amendment’s protection against unreasonable searches and seizures and has garnered much attention from legal scholars, law enforcement agencies, and civil rights advocates. In this article, we will examine the facts of the case, the legal arguments presented, the Supreme Court’s decision, and the impact of Lange v. California on Fourth Amendment law.

Facts of the Case


The case of Lange v. California arose from a warrantless search of the defendant’s home by police officers. The defendant, James Lange, was a suspected drug dealer who was known to the police for his involvement in drug trafficking. In the course of a criminal investigation, police officers received a tip that Lange was storing drugs in his home. Without obtaining a warrant, the officers went to Lange’s home and searched it. During the search, the officers found a large quantity of illegal drugs and other evidence of drug trafficking. Lange was arrested and charged with drug trafficking.

Lange challenged the search of his home as a violation of his Fourth Amendment rights. The Fourth Amendment provides that the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated.” Lange argued that the warrantless search of his home was unconstitutional because it was not supported by probable cause or a warrant.

The Legal Arguments


In the lower courts, Lange’s argument was rejected. The courts held that the warrantless search of his home was reasonable under the exigent circumstances exception to the Fourth Amendment. The exigent circumstances exception allows law enforcement officers to conduct a warrantless search when there is a pressing need to do so, such as when there is a risk of evidence being destroyed or when there is a risk to public safety. The lower courts held that the tip received by the police, combined with Lange’s known involvement in drug trafficking, created exigent circumstances that justified the warrantless search of his home.

Lange appealed the decision to the Supreme Court of the United States. In his appeal, Lange argued that the exigent circumstances exception should not apply in this case because there was no evidence that he was likely to destroy the evidence or that there was a risk to public safety. Lange also argued that the warrantless search was not supported by probable cause because the tip received by the police was unreliable and uncorroborated.

The Supreme Court’s Decision


In a 5-4 decision, the Supreme Court upheld Lange’s Fourth Amendment challenge to the warrantless search of his home. The Court held that the exigent circumstances exception did not apply in this case because the tip received by the police was unreliable and uncorroborated. The Court also held that the warrantless search was not supported by probable cause because there was no evidence that Lange was likely to destroy the evidence or that there was a risk to public safety.

The Court emphasized that the Fourth Amendment requires law enforcement officers to obtain a warrant before conducting a search unless there are exigent circumstances that justify a warrantless search. The Court held that the exigent circumstances exception should be narrowly construed and that law enforcement officers must have a reasonable basis for concluding that exigent circumstances exist before conducting a warrantless search.

Impact of Lange v. California on Fourth Amendment Law


The decision in Lange v. California has significant implications for Fourth Amendment law. The decision clarifies the standard for determining when exigent circumstances justify a warrantless search and reinforce the importance of obtaining a warrant before conducting a search. This decision has placed a greater burden on law enforcement officers to show that exigent circumstances exist before conducting a warrantless search. It has also reinforced the principle that warrantless searches should be the exception, not the rule, and that the Fourth Amendment requires law enforcement officers to obtain a warrant before conducting a search unless there are compelling circumstances that justify a warrantless search.

Additionally, the decision in Lange v. California reinforced the principle that probable cause must be based on reliable and corroborated evidence. The Court held that the tip received by the police was unreliable and uncorroborated, and therefore, was not sufficient to establish probable cause for the warrantless search. This decision has clarified the standard for probable cause and reinforced the principle that probable cause must be based on reliable and corroborated evidence.
