Which would supreme court justice write if he or she disagreed with a ruling of the court?

If a Supreme Court justice disagrees with a ruling of the court, they would typically write a dissenting opinion. This opinion outlines their reasons for disagreeing with the majority's decision, often highlighting legal principles, precedents, and alternative interpretations of the law. Dissenting opinions can influence future cases and provide a counterargument that may resonate with later courts or justices.
