Marshall had been looking for a case that was suitable for introducing judicial review, and was eager to use the situation in "Marbury" to establish his claim. He introduced judicial reviewa move Jefferson decriedbut used it to strike down a provision of a law that he read to have expanded the Supreme Court's powers, and thereby produced Jefferson's hoped-for result of Marbury losing his case. He "seized the occasion to uphold the institution of judicial review, but he did so in the course of reaching a judgment that his political opponents could neither defy nor protest." Though Jefferson criticized Marshall's opinion, he accepted it, and Marshall's decision in "Marbury" "articulate a role for the federal courts that survives to this day." The American legal scholar Erwin Chemerinsky concluded: "The brilliance of Marshall's opinion cannot be overstated."
