"President Roosevelt clearly had the right to send to the United States Senate and the United States Congress a proposal to pack the court. He violated no law. He was legalistically, absolutely correct, but it was a bonehead idea. It was a terrible, terrible mistake to make. And it put in question, for an entire decade, the independence of the most significant body - including the Congress included in my view - in this country, the Supreme Court of the United States of America."
