The exclusionary rule is a legal principle that prevents the admission of evidence obtained through illegal means, such as unlawful searches and seizures. It is designed to protect individuals' Fourth Amendment rights against unreasonable searches. 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 exclusionary rule bans illegally obtained evidence from being used in court during the trial phase.
The exclusionary rule.
If an officer were to obtain evidence illegally, such as searching you without probable cause, the evidence they acquired would not be admissible in court. That's not to say the entire case would be thrown out, but that single piece of evidence would not be allowed in court. The exclusionary rule doesn't prevent unlawful searches and seizures, but it disincentivizes them by making evidence seized unlawfully inadmissible at trial. There's no reason to illegally obtain evidence if it can't be used to convict a defendant.

No, evidence obtained illegally, including letters that were opened without permission, is generally not admissible in court due to the exclusionary rule, which prohibits the use of illegally obtained evidence in legal proceedings.
The fruit of the poisonous tree doctrine states that evidence obtained illegally or unconstitutionally cannot be used in court, along with any other evidence that stems from it. The exclusionary rule, on the other hand, is a legal principle that prohibits evidence obtained in violation of the defendant's constitutional rights from being used in court.

In Weeks v. United States, 232 U.S. 383 (1914), the United States Supreme Court unanimously held that the warrantless seizure of items from a private residence constitutes a violation of the Fourth Amendment.

The exclusionary rule is grounded in the Fourth Amendment and it is intended to protect citizens from illegal searches and seizures." The exclusionary rule is also designed to provide a remedy and disincentive, which is short of criminal prosecution in response to prosecutors and police who illegally gather evidence in violation of the Fifth Amendment in the Bill of Rights compelled to self-incrimination. The exclusionary rule also applies to violations of the Sixth Amendment, which guarantees the right to counsel.
In a criminal procedure, the inevitable discovery rule allows evidence of a defendant's guilt to be admitted as evidence in a trial. The exclusionary rule judges the admissibility of evidence and under the constitutional law, the evidence collected or analyzed in violation of the defendant's constitutional rights is sometimes inadmissible for a criminal prosecution in a court of law. In simple terms, the inevitable discovery exception to the exclusionary rule allows into evidence illegally seized items that would have been discovered lawfully anyway. This exception allows evidence to be admitted, even though it was seized in violation of the Constitution. In order to successfully assert the inevitable discovery exception, some courts require that the prosecution demonstrate that the police were in the process of actively pursuing a lawful investigation that would have led inevitably to the discovery of the evidence at the time that the evidence was illegally obtained.
The fruit of the poisonous tree doctrine and the exclusionary rule are related in criminal law. The doctrine states that evidence obtained illegally or through a violation of constitutional rights is considered tainted, like a poisoned tree, and any evidence derived from it is also tainted and inadmissible in court. The exclusionary rule is a legal principle that prohibits the use of illegally obtained evidence in court proceedings. Therefore, the exclusionary rule is often applied in cases where the fruit of the poisonous tree doctrine is relevant, as it serves to exclude tainted evidence from being used against a defendant in a criminal trial.
