A more thorough explanation:

Vega v. Tekoh (2022) is a Supreme Court case that ruled that a violation of Miranda Rights does not necessarily provide a basis for relief under 42 U.S. Code § 1983.

The case involved the interrogation of Terence Tekoh by Deputy Carlos Vega. Vega questioned Tekoh at his workplace but did not inform him of his Miranda rights. Tekoh provided a written statement that admitted guilt, which was later used in trial. After a jury found Tekoh not guilty, he sued Vega under 42 U.S.C § 1983 (Civil Action for Deprivation of Rights).

The Supreme Court decided that a violation of Miranda does not necessarily constitute a violation of the Fifth Amendment right against compelled self-incrimination. The Court stated that Miranda imposed "a set of prophylactic rules" but did not hold that a violation of those rules necessarily constituted a Fifth Amendment violation. The Court further determined that post-Miranda decisions had balanced interests that justified restrictions that would not have been possible if a Miranda violation was a Fifth Amendment violation. Additionally, the Court establishes that "a judicially crafted prophylactic rule" should only apply "where its benefits outweigh its costs."

This decision has implications for the use of Miranda warnings and qualified immunity. It means that a violation of Miranda does not necessarily provide a basis for relief under 42 U.S. Code § 1983.

If a police officer fails to read a suspect their Miranda rights before questioning them, the suspect's confession may still be admissible in court if the court determines that the failure to read the Miranda rights did not violate the suspect's Fifth Amendment rights.
