Answer:
They felt that it was an attempt to gain influence on the Supreme Court
Step-by-step explanation:
The critics view the judicial reform bill under Franklin Roosevelt as "an attempt to gain influence on the Supreme Court."
This is because, before the judicial reform bill under Franklin Roosevelt, several New Deal measures got struck down by the Supreme Court.
Hence, Roosevelt carried out Judicial reform (in which the president has the power to appoint up to six Supreme court justice) which added more justices to the Supreme Court justices.
This was believed to be an attempt to gain influence on the Supreme Court to get his New Deal measures approved by the Supreme Court.
