In "Fletcher v. Peck" (1810), Johnson joined the majority of the Court to hold that a Georgia law voiding land grants given by the state the year prior was unconstitutional. It was the first time the Supreme Court ruled a state law as such. Johnson wrote a concurrence in "Fletcher." He did not disagree with the Court's overall holding, but he feared the case may have been "feigned" due to possible collusion between the parties in order to establish precedent. He also disagreed with Marshall's reasoning that the Georgia law violated the Contract Clause. He believed Marshall's interpretation of the Contract Clause, that impairments to contract obligations violated it, as overly broad and unnecessarily restrictive of state powers in favor of private rights. Instead, he believed the law violated the general principle of law that one could not revoke ownership in something one no longer owned.
