Which Supreme Court case established guidelines for the Jackson vs. Denno Hearing?

The case that established guidelines for the Jackson v. Denno hearing is State v. Parker (2008). This decision provides important criteria for evaluating the voluntariness of a suspect's confession. The Jackson v. Denno hearing is specifically designed to determine whether a confession offered by a defendant was made freely and voluntarily, without coercion, and the court in Parker set standards for how this evaluation should be conducted in a legal context.

The specifics of this case emphasize the need for a preliminary judicial examination to assess the circumstances surrounding the confession, deliberating on factors such as the defendant's age, mental state, and the methods used by law enforcement during the interrogation. This highlights the court's commitment to ensuring that confessions introduced in court are reliable and obtained fairly, safeguarding defendants' rights within the judicial system.
