Colorado v. Connelly (Supreme Court, 1986): The Supreme Court determined competency to confess is dependent on whether or not: (1) The confession is VOLUNTARY and free from susceptible coercion; (2) Waiver of Miranda Rights is voluntary, and (3) The defendant’s reliability is impaired by any mental disability. Statements made by defendants are admissible regardless of mental state unless the defendant did not understand their Miranda rights (The right to remain silent).
