federal court rule

Abbott Laboratories manufactured and sold the Life Care PCA, a pump that delivers medication into a person intravenously at specific time intervals. Beverly Lewis sued Abbott in a Mississippi state court, alleging that a defective Life Care PCA had injured her by delivering an excessive quantity of morphine. Abbott served Lewis with a request for admission calling for her to admit that her damages did not exceed $75,000. Lewis did not answer the request for admission. Abbott removed the case to the U.S. District Court for the Southern District of Mississippi, predicating the court’s subject- matter jurisdiction on diversity of citizenship and an amount in controversy exceeding $75,000. Contending that her silence had amounted to an admission that her damages were less than $75,000, Lewis fi led a motion asking that the federal court remand the case to the state court. Did the federal court have subject-matter jurisdiction? How did the federal court rule on Lewis’s motion to send the case back to the state court?
