How many justices must agree to an opinion for the Supreme Court to issue a decision?

five of the nine justices

Explanation:

The Supreme Court of the U.S.A is the only court that the Constitution has expressly established, making it the most powerful court in the country. At least five of the nine justices have to consent to a final decision. The judges of the Court debate the cases together and often tend to persuade each other to support their way of thinking. One or more of those judges is expected to write the "majority opinion," while those who disagree may write a "minority opinion." Both opinions are reported, but the final decision is the majority opinion.
