It&#x27;s amazing what you can do when you threaten to pack the court.  When the Supreme Court blocked a lot of New Deal and state-level regulations as unconstitutional, FDR threatened to appoint enough new justices to get the decisions he wanted (there is no limit to the number of justices in the Constitution).  That was the end of the Lochner era of American jurisprudence and was a tragedy for freedom.  We&#x27;re still suffering the consequences today.
