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.
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. It also set forth the exclusionary rule that prohibits admission of illegally obtained evidence in federal courts.See below link:
No, evidence illegally seized by the police cannot be used in a trial due to the exclusionary rule, which prohibits the use of evidence obtained in violation of a person's constitutional rights.

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 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 trial, it would constitute "Fruits of the Poisonous Tree", and the evidence would be excluded from trial via Exclusionary Rule.
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.
No, it is generally not permissible to use illegally obtained evidence in court.
To come into a home the police need a search warrant to search. Without the warrant the evidence is not admissible in court. It would be an illegal search.
The Exclusionary Rule's purpose is to keep certain evidence from being used against you in a criminal trial. Police procedure in gathering evidence against you is heavily dictated by cases interpreting the Fourth Amendment. Evidence gathered in violation of your Constitutional rights is subject to the Exclusionary Rule.
The general doctrine courts follow is called "fruit of the poison tree." If a defendant's rights were violated, then any evidence deriving either directly or indirectly from that violation is inadmissible in court. The violation "poisons" the evidence obtained illegally and any other evidence discovered as a result. It is not, however, a "get out of jail free" card. If the police illegally search your home without a warrant and find heroin there, they cannot use that as evidence. They can, however, use the surveillance video taken of you two weeks ago showing you selling heroin in the park that made them want to search your home in the first place as evidence.
No, it is generally not permissible to use illegally obtained evidence in civil court proceedings.
