How many Supreme Court justices are usually needed to decide a case?

In Chinese 通常需要几位最高法院大法官才能对案件作出裁决?

Official answer

  • Five (5)5 位

Why this is the answer

Supreme Court cases are decided by majority vote. With nine justices, five votes make a majority, so five justices are usually needed to decide a case. The side with at least five votes wins, and one justice in the majority usually writes the Court's opinion explaining the decision.
