What helps Supreme Court justices feel less pressure regarding their decisions?

The appointment of Supreme Court justices for life plays a crucial role in allowing them to feel less pressure regarding their decisions. This lifetime tenure means that justices do not have to run for election or reappointment, which removes the burden of political influence or public opinion that might otherwise affect their rulings. This system is designed to ensure that justices can make decisions based on the law and their interpretation of the Constitution without fear of losing their positions due to unpopular decisions. The independence afforded by lifetime appointments supports the judicial branch's role in checking and balancing the power of elected officials and maintaining integrity in the law. In contrast to the other options, which suggest external influences or pressures, the lifetime appointment empowers justices to focus solely on their legal responsibilities.
