What legal document explains the legal reasoning behind a Supreme Court decision? 1. The majority opinion 2. The minority opinion 3. Stare decisis 4. Amicus curiae

Answer: The correct answer is Themajority opinion.

Explanation: The term majority opinion refers to the judicial opinion which is agreed by more than half of the judicial committee. The majority opinion also gives an explanation for the rationale behind the court's decision.

It would be "1. The majority opinion" that enables the Supreme Court to make its decision, since it is made up of nine members--meaning that landing on a "tie" is impossible.
