Packing the court

After years of contention, Congress passed legislation to expand the size of the Supreme Court and the president signed it.
The Court immediately tried to review the law and declare it unconstitutional.
But the House filled the airwaves with meaningless impeachment hearings, and Senate and President ignored the Supreme Court, nominating Associate Justices and holding confirmation hearings.
The opposition party protested the move, doing all they could to disrupt the meetings and votes.
When the new Associate Justices descended on the Supreme Court, the Chief Justice refused to administer their Constitutional Oaths.
Which party was which?
Does it really matter?
