Whether the $50,000 amount-in-controversy requirement governed this diversity action.
Holding
Yes. Because Gaus commenced the action after the statutory effective date, he had to satisfy the $50,000 jurisdictional threshold.
Reasoning
Congress raised the diversity-jurisdiction amount from $10,000 to $50,000 through the Judicial Improvements and Access to Justice Act. The amendment applied to civil actions commenced on or after May 18, 1989.
Gaus filed his complaint on May 25, 1990. Thus, the new $50,000 threshold, rather than the former $10,000 threshold, controlled whether the federal court had diversity jurisdiction. A complaint seeking merely “in excess of $10,000” did not itself establish the required amount.
