In Johnson v. Massachusetts (1967), the U.S Supreme Court ruled in favor of the state, upholding a law that allowed for involuntary commitment to mental institutions without a jury trial. The case was brought forward by Ora Lee Johnson who had been involuntarily committed to a mental institution under Massachusetts law which did not require her consent or a jury trial. She argued that this violated her constitutional rights, specifically the Fourteenth Amendment's due process clause and Sixth Amendment's right to a jury trial. However, the court held that states have an interest in providing care for their citizens who are unable to care for themselves due to mental illness and can do so without violating their constitutional rights as long as there is clear medical evidence supporting such action.

In the dissenting opinion for Johnson v. Massachusetts, the justice argued that there was a lack of sufficient evidence to support the conviction of Johnson for being an accessory before the fact to armed robbery. The justice contended that while it was clear from testimonies and circumstantial evidence that Johnson had been present at some point during planning discussions, this alone did not constitute proof beyond reasonable doubt of his active participation or encouragement in carrying out the crime itself. Furthermore, they pointed out inconsistencies in witness accounts regarding whether he had actually been aware beforehand about specific details such as use of firearms or exact timing. They also questioned why other individuals who were similarly involved but played lesser roles were not prosecuted too. Therefore, they believed it was unjust to hold him accountable based on mere association with perpetrators without concrete proof showing his direct involvement in facilitating their criminal act.
