Is it true that rejected preventive detention in stack v Boyle 1951?

Yes, in Stack v. Boyle (1951), the U.S. Supreme Court rejected the use of preventive detention for bail in cases where the defendant posed a flight risk. The Court ruled that bail should not be set higher than necessary to ensure a defendant's appearance in court, emphasizing that excessive bail is prohibited by the Eighth Amendment. The decision underscored the principle that bail is not meant to serve as a form of preventive detention.
