Do split decisions in the Supreme Court have the same effect as unanimous decisions?

No, split decisions in the Supreme Court do not have the same effect as unanimous decisions. A split decision often reflects differing opinions among justices, which can lead to ambiguity in the interpretation of the law and may create precedent that is less clear. In contrast, a unanimous decision signifies a strong consensus, providing clearer guidance and stability in legal interpretation. Consequently, unanimous rulings typically carry more weight and authority in future cases.
