Answer 1

Yes, but the court has given unconstitutional rulings which was proposed by former US President Franklin Roosevelt and called it Judicial Procedures Reform Bill of 1937 to add more justices

Answer 2

The correct answer to this open question is the following.

Had Congress allowed six more justices onto the Supreme Court this might have this changed the balance of powers in a more strong and powerful Supre Court.

Franklin D. Roosevelt needed more support to pass his "New Deal" program. Roosevelt needed more judges for the approval of his program. So the legislative initiative that President Roosevelt proposed was called the "court-packing plan," to increase the number of justices in the Supreme Court. The formally known as the Judicial Procedures Reform Bill of 1937 consisted of granting the President power to appoint up to six justices to the Supreme Court for every member of the court who had 70 years-old.
