Which Supreme Court case established that psychotherapist-client communications are privileged?

The Supreme Court case that established the privilege of psychotherapist-client communications is Jaffee v. Redmond. This landmark ruling recognized that the confidentiality of communications between a patient and a psychotherapist is essential for effective treatment and is protected under the evidentiary privilege. The Court acknowledged that having a confidential relationship encourages patients to speak freely and honestly, which is vital for their recovery.

This case affirmed that the therapeutic alliance depends on the assurance that personal disclosures will remain confidential, making it a critical precedent in ensuring the protection of mental health clients' rights within the legal framework. By establishing this privilege, the Court reinforced the importance of confidentiality in therapy, which in turn supports not only individual treatment but also public health.

In this context, it’s important to recognize that while other cases mentioned may touch upon aspects of client rights or confidentiality, they do not specifically address the psychotherapist-client privilege in the same way that Jaffee v. Redmond does.
