米最高裁、トランプ大統領の世界関税の合法性判断を保留

The evidence from the provided sources strongly and consistently supports the statement that the U.S. Supreme Court has not yet issued a ruling on the legality of the tariffs. The most authoritative source, the Council on Foreign Relations, directly states that the Supreme Court is "expected to issue rulings," clearly indicating a decision is pending. This is strongly corroborated by two other high-authority sources. A CNBC report notes that new tariff threats "hinge on [the] Supreme Court decision," framing the ruling as a crucial future event. Similarly, a Bloomberg article speculates about the potential outcomes "If the Supreme Court Says His Tariffs Are Illegal," which presupposes that no ruling has been issued. The remaining two sources have low relevance to the specific question and do not provide any information about the Supreme Court's actions, therefore they do not contradict the other evidence. The consistent narrative across three credible, independent sources provides a high degree of confidence in the statement's truthfulness.
