who holds the privilege when it concerns attorney-client communication
Attorney–client privilege In the law of the United States, attorney–client privilege or lawyer–client privilege is a "client's right privilege to refuse to disclose and to prevent any other person from disclosing confidential communications between the client and the attorney."[1]
Gideon v. Wainwright Gideon v. Wainwright, 372 U.S. 335 (1963), is a landmark case in United States Supreme Court history. In it, the Supreme Court unanimously ruled that states are required under the Sixth Amendment to the U.S. Constitution to provide an attorney to defendants in criminal cases who are unable to afford their own attorneys. The case extended the right to counsel, which had been found under the Fifth and Sixth Amendments to impose requirements on the federal government, by imposing those requirements upon the states as well.
