Judicial activism is condemned by both right and left, for good reason—lawless courts are a threat to republican government. But challenging conventional wisdom, constitutional litigator Clint Bolick argues in David's Hammer: The Case for an Activist Judiciary that far worse is a judiciary that allows the other branches of government to run roughshod over precious liberties. For better or worse, only a vigorous judiciary can enforce the limits on executive and legislative action, protect constitution-al rights, and tame unelected bureaucrats. David's Hammer reclaims for the judiciary its intended role as the ultimate safeguard of a free society.
