No interlocutory appeal of discovery order

The appellant in All Plaintiffs v. Transocean Offshore (the MDL relating to Deepwater Horizon) challenged an order requiring him to submit to a psychiatric exam and supply medical records as part of the procedure.  No. 12-30237 (Jan. 3, 2013, unpublished).  Following Mohawk Industries v. Carpenter, 130 S. Ct. 599 (2009), the Fifth Circuit held that the collateral order doctrine did not allow appeal of this interlocutory discovery order.  Any erroneous effect on the merits of the case could be reviewed on appeal of final judgment, and even if that review was “imperfect[]” to remedy the intrusion on his privacy interest, the harm was not so great as to justify interlocutory review of the entire class of similar orders.  A concurrence noted that while mandamus review was theoretically possible, this party had not requested it as an alternative to direct appeal, and had not made a sufficiently specific showing of harm to obtain mandamus relief.
