Frequently Asked

What must a defendant file to remove a civil action to a United States District Court?+
A defendant must file a notice of removal in the district court for the district and division where the state action is pending. The notice must be signed under Rule 11, contain a short and plain statement of the grounds for removal, and include copies of all process, pleadings, and orders served on the defendant.

How do United States District Courts exercise their gatekeeping role regarding expert testimony?+
District courts assess both the reliability and relevance of expert testimony. They may exclude an opinion when there is too great an analytical gap between the data and the proffered conclusion or when the expert's methodology lacks sufficient factual support.
Supporting sources
Can a United States District Court transfer a case when it lacks personal jurisdiction over the defendant?+
Yes. A district court without personal jurisdiction may still transfer the action under 28 U.S.C. § 1406(a) to a district where the action could have been brought if transfer serves the interest of justice.
