A precedent was set 90 years ago limiting presidential authority to fire the heads of independent agencies without cause. Consistent with the legislative intent of Congress and the Founder's design.
According to press accounts I've seen the Court's conservatives look ready to ignore all that and grant even more power to the most malevolent POTUS in the country's history. Basing the ruling on an ahistoric belief, antithetical to our history (which is why the justices were chosen), that the prez should have unchecked power over personnel staffing agencies created by Congress with the express purpose of being beyond the prez's whims.
John Roberts is reported to feel the legacy of the court he leads is important to him. I wonder if he understands its legacy will be one of making some of the most radical, unfounded, history altering rulings in contradiction to stare decisis by a SC in two centuries?
