Task: Wrong Candidate Generation
Input (English): the action should pro ceed among the existing parties or be dismissed. Fed.R.Civ.P. 19(b). Defendant neglected to offer any explanation for how and why Mr. Stroud is essential, other than that he was named in the underlying state court case. That is not enough. Mr. Stroud is not a necessary or indispensable party under Rule 19 because this Court can administer complete relief — an order compelling arbitration— among the existing parties and Mr. Stroud himself is not claiming an interest in this arbitration action that will be impaired by his absence.

Output (English): holding that district courts are required to compel arbitration of claims subject to arbitration clause even if the result is piecemeal litigation
