The more conservative members of the court upheld the principles of the Lochner era, which saw numerous economic regulations struck down on the basis of freedom of contract.[194] Roosevelt proposed the Judicial Procedures Reform Bill of 1937, which would have allowed him to appoint an additional Justice for each incumbent Justice over the age of 70; in 1937, there were six Supreme Court Justices over the age of 70. The size of the Court had been set at nine since the passage of the Judiciary Act of 1869, and Congress had altered the number of Justices six other times throughout U.S. history.[195] Roosevelt's "court packing" plan ran into intense political opposition from his own party, led by Vice President Garner since it upset the separation of powers.[196] A bipartisan coalition of liberals and conservatives of both parties opposed the bill, and Chief Justice Charles Evans Hughes broke with precedent by publicly advocating the defeat of the bill. Any chance of passing the bill ended with the death of Senate Majority Leader Joseph Taylor Robinson in July 1937.
