Illegally seized evidence may not be used in a trial due to the exclusionary rule, which prohibits the use of evidence obtained in violation of a defendant's constitutional rights, particularly the Fourth Amendment's protection against unreasonable searches and seizures. Allowing such evidence would undermine the integrity of the judicial system and potentially encourage law enforcement to disregard constitutional protections. This principle aims to deter unlawful police conduct and ensure fair trial standards.
The decision that established that evidence obtained illegally violates the Fourth Amendment is Mapp v. Ohio (1961). In this landmark case, the U.S. Supreme Court ruled that the exclusionary rule, which prevents the use of illegally obtained evidence in court, applies to state courts as well as federal courts. This decision reinforced the principle that individuals have a constitutional right to be free from unreasonable searches and seizures.

The exclusionary rule is a legal principle that prevents the admission of evidence obtained through illegal means, such as unlawful searches and seizures.

When evidence is deemed inadmissible due to its illegal acquisition, it cannot be used in court to prosecute a defendant. This rule aims to deter law enforcement from violating constitutional rights during investigations.
The Supreme Court used the Fourth Amendment, which protects against unreasonable searches and seizures, to reach its decision regarding the use of illegally obtained evidence. This principle was established in the landmark case Mapp v. Ohio (1961), where the Court ruled that evidence obtained in violation of the Fourth Amendment cannot be used in state courts. The ruling reinforced the exclusionary rule, ensuring that citizens are protected from unlawful evidence in criminal prosecutions.
The Fourth Amendment protects individuals from unreasonable searches and seizures, requiring law enforcement to obtain a warrant based on probable cause before conducting searches. This amendment ensures that citizens have a right to privacy, limiting police powers and establishing legal standards for obtaining evidence. Consequently, law enforcement agencies must adhere to these constitutional protections, which can impact their investigative procedures and the admissibility of evidence in court. Failure to comply with the Fourth Amendment can lead to evidence being deemed inadmissible, potentially undermining criminal cases.

In Smith v. Jones, 113 U.S. 23, the Supreme Court addressed the issue of whether certain evidence obtained without a warrant should be admissible in court. The Court held that the Fourth Amendment's protection against unreasonable searches and seizures applies to the states through the Fourteenth Amendment. Consequently, the evidence in question was deemed inadmissible, reinforcing the principle that law enforcement must adhere to constitutional standards when conducting searches. This decision underscored the importance of safeguarding individual rights against government overreach.
