I mean the pardon was the check and balance on the judiciary. However it's been turned into a tool for personal gain than a saving grace for mistakes of the federal crimes convictions. Both parties have pushed for this monarchic power to be expanded over time. I think it has a place but much like a lot of the federal government it needs a complete overhaul. The checks and balances system works alright but when a unitary party controls every branch there is no one to check that power.
