ess consider his petition for writ of mandamus.
Mandamus is an extraordinary remedy and is available only in limited circumstances of manifest and urgent necessity. See Holloway v. Fifth Court of Appeals, 767 S.W.2d 680, 684 (Tex.1989) (orig.proceeding). Thus, a writ of mandamus issues only to correct a clear abuse of discretion or the violation of a duty imposed by law when there is no other adequate remedy at law. Johnson v. Fourth Court of Appeals, 700 S.W.2d 916, 917 (Tex.1985). A trial court abuses its discretion only when its decision is so arbitrary and unreasonable that the decision amounts to a clear and prejudicial error of law. Cent. Nat'l Ins. Co. Of Omaha v. Lerner, 856 S.W.2d 492, 494 (Tex.App.-Houston [1st Dist.] 1993, orig. proceeding). Interference through the issuance of a writ of mandamus is justified "when parties stand to lose their substantial rights." Walker v. Packer, 827 S.W.2d 833, 842 (Tex.1992) (orig.proceeding) (quoting Iley v. Hughes, 158 Tex. 362, 311 S.W.2d 648, 652 (1958)(orig.proceeding)).
We have held above that the trial court's order staying arbitration was not an appealable, interlocutory order. Furthermore, because the trial court's order requires the parties to litigate the issue of Jeanie's standing before presumably resuming arbitration, Billy and Lynn will have been "deprived of the benefits of the arbitration clause ..., and the purpose of providing a rapid, inexpensive alternative to traditional litigation would be defeated." See In re MHI P'ship, Ltd., 7 S.W.3d 918, 921 (Tex.App.-Houston [1st Dist.] 1999, orig. proceeding) (citing Jack B. Anglin Co. v. Tipps, 842 S.W.2d 266, 272-7 (Tex. 1992)). Thus, provided the trial court committed a clear abuse of discretion in rendering the order, mandamus will lie. See id.
