When an action is removed on the basis of diversity, the requisite diversity must exist at the time the action is removed to federal court. C. Wright,
Law of Federal Courts
§ 38, at 153 (3d ed. 1976); 14A C. Wright, A. Miller & E. Cooper,
Federal Practice and Procedure
§ 3723, at 311 (2d ed. 1985);
see Desert Empire Bank v. Insurance Company of North America,
The diversity upon which removal is predicated must be complete,
see Strawbridge v. Curtiss,
7 U.S. (3 Cranch.) 267,
On the face of the pleadings in this case, there is a substantial question concerning the plaintiffs citizenship at the time of removal. Accordingly, the judgment of the district court is vacated and the case is remanded to the district court. The district court should determine whether diversity has been established under the principles we have set forth. If the requisite diversity is lacking, the district court should remand the action to state court. If diversity is established, the district court may reinstate its judgment. If a new notice of appeal is filed, the briefs and record in this case shall be transferred to the new appeal.
REMANDED.
