July 25, 1958
In 1958, Congress further limited the scope of removal in cases based on diversity of citizenship. The amount in controversy requirement was raised from $3,000 to $10,000 and removal in workers’ compensation cases was eliminated. Moreover, Congress declared that corporations – which had since the Supreme Court's 1844 decision in Louisville Railroad Company v. Letson been considered citizens only of their state of incorporation – were also citizens of the state in which they primarily did business, thereby reducing the number of diversity jurisdiction cases involving corporate parties.
