Answer:
3. Judicial appointments and confirmations
Explanation:
This is the main way in which the Supreme Court can see its power restricted. While judicial appointments and confirmations do not legally change the Court's jurisdiction, they can nevertheless cause a shift in the ideology of the Court. This shift means that the Court might be more willing to discuss certain cases over others in a way that differs from how it operated before the appointments or confirmations. Moreover, these processes force the Court to be in constant collaboration with the other branches of government, which inevitably restricts the Court's actions and liberties to an extent.
