The Supreme Court overturned a 90-year-old decision that allowed Congress to shield members of certain independent agencies from being fired by the president at will.

The Supreme Court on Monday ruled that removal protections for members of the Federal Trade Commission are unconstitutional and overturned a 90-year-old decision that allowed Congress to shield members of certain independent agencies from being fired by the president at will.

The decision from the high court expands the president’s power over many independent boards and commissions, which Congress had insulated from political pressure by saying their members could only be removed by the president for cause.
