What is the term length for a Supreme Court Justice?

The term length for a Supreme Court Justice is indeed lifetime. This means that justices serve for life unless they choose to resign, retire, or are removed through impeachment. The framers of the U.S. Constitution intended this lifetime appointment to ensure judicial independence, allowing justices to make decisions based on their interpretation of the law without fear of political pressure or influence from external factors, such as elections or the whims of politicians.

This concept is designed to protect the judiciary from the volatility of political shifts and to uphold the integrity of judicial decisions over time, fostering a stable interpretation of the Constitution and federal law. The options suggesting specific time frames or conditional terms do not align with the original design of the Supreme Court's structure as established by the Constitution.
