Armco, Inc., FMC Corporation, IBM Corporation, and AT & T Technologies, Inc., petition this Court for a writ of mandamus to revoke the authоrity of the Special Master to prepare a report and reсommendation pertaining to liability and remedy in this environmental litigation initiated under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA), 42 U.S.C. §§ 9606(a) and 9607(a). The government’s response to the petition for writ of mandamus also urged the revocation of the Special Master’s authority to preside at trial. In a separate filing, the district court defended its referencе to the master. After a careful review of the materials submitted by all the pаrties, we uphold the district court’s reference to the Special Mastеr, but with specified limitations on the master’s authority.
*105 The standard for evaluating refеrences to a master is set out in Fed.R.Civ.P. 53(b), which provides in pertinent part:
A reference to a master shall be the exception and not the rule. In aсtions to be tried by a jury, a reference shall be made only when the issues are complicated; in actions to be tried without a jury, save in matters of aсcount and of difficult computation of damages, a reference shall be made only upon a showing that some exceptional condition requires it.
The courts have tended to read the rule somewhat narrowly, closеly circumscribing the range of circumstances in which reference to a mаster is appropriate. In
LaBuy v. Howes Leather,
The principal matter at issue is the scope of the district court’s reference to the magistrate; petitioners complain that the circumstances do not justify reference of all pretrial and discоvery matters as well as the conduct of trial on the merits, including the prepаration of findings of fact and conclusions of law. Although
LaBuy
and
Liptak
limit the authority of the master,
La-Buy
was a case in which а district court had abused its authority to appoint masters. Other cases help ascertain the breadth of his powers within those limits.
California v. Texas,
We believe that the district court erred in granting the master authority to preside at trial on the merits of this cаse. We also believe, however, that the district court acted proрerly in granting the master the broad authority to supervise and conduct pretriаl matters, including discovery activity, the production and arrangement of exhibits аnd stipulations of fact, the power to hear motions for summary judgment or dismissal аnd to make recommendations with respect thereto. If the district court dеtermines that liability rests with some or all of the parties, it may request the master to conduct evidentiary rehearings with respect to damages and alternаtive relief and make recommendations with respect to these mattеrs. It may also direct the magistrate to monitor and supervise any injunctive reliеf granted and to make reports to it with respect to compliance with any decrees entered.
Therefore, we issue the writ of mandamus and direct the district court to revise its reference of this case to the master, in accordance with the opinion of this Court.
