Reporter’s Notes
Reporter's Notes (1997) Rule 53(b)(2) was added which allows the court to inquire as to whether the parties can agree upon a master. The court would have the discretion to appoint the mutually agreed upon master or another suitable person.
Plain-English Summary
Rule 53 is the longest rule in Part VI and the one most used in this court. A master hears evidence and reports facts, and the rule builds a small procedural system around that.
Who, and the five-day objection
A master is any person, however designated, appointed by the court to hear evidence and report facts. No one may be appointed who is not a member in good standing of the bar of one of the United States or the District of Columbia, and in the District Court no master may be appointed without the assent of all parties. Appointment is subject to any standing order of the Administrative Justice designating classes of cases not to be tried to a master.
Before appointing, the court may inquire whether the parties can agree on a master, and may appoint the person agreed upon or another suitable person — added in 1997, as the Reporter's Note records.
A party objecting to the appointment must file a written objection within five days of notice of the appointment, and the clerk forwards notice of the filing to the referring justice. The grounds are not included in the written objection — they are furnished to the referring justice on request, in the form that justice orders.
What the master must disclose
On receiving the order of reference the appointee must tell the referring justice immediately if unable or unwilling to serve. No person shall accept appointment as master in any case in which he cannot be impartial. Where circumstances known to the master may give the appearance of partiality — including any pending matter between the master and a party or a party's counsel — the master must make full written disclosure to the referring justice and all parties immediately after receipt of the order.
The order of reference, and running the hearing
The appointment is by written order of reference, which must fix the times for hearings or the window in which they begin and end, must fix the time for filing the report, and may limit the master's powers or direct a report on particular issues only.
Hearings proceed as nearly as possible on consecutive days, with no adjournment longer than three days except by order of the court, and either party may apply to the court to speed the proceedings. Rules 43(a), (b), (d) and (g) govern the evidence. Where an objection is sustained and a stenographer is present, the master shall on request take the proffered evidence as an offer of proof unless it is privileged.
If all parties fail to appear without good cause, the master reports forthwith to the clerk, who brings it to the referring justice. If one party fails to appear, the master may proceed ex parte, adjourn with notice, or apply to the court for sanctions. Witnesses are compelled by subpoena under Rule 45, and a witness who fails to appear without adequate excuse may be punished as for a contempt.
The report
The report contains general findings on each issue within the order of reference and clearly identified subsidiary findings on which each general finding is based — and no general finding will be presumed to be supported by subsidiary findings not stated in the report.
At least ten days before filing, the master submits a draft to counsel for all parties, who may submit written suggested amendments with copies to everyone. The master may allow a hearing on them, and must circulate any adopted amendment with the filing. The report and original exhibits are filed within thirty days after the close of the evidence unless the court alters the time for good cause, and the clerk mails notice of filing to all parties.
Review
In a non-jury case the court accepts the master's subsidiary findings unless they are clearly erroneous, mutually inconsistent, unwarranted by the evidence as a matter of law, or otherwise tainted by error of law — and a party contending any of that must say so by objection. The court may draw its own inferences from the subsidiary findings, and may make additional Rule 52 findings not inconsistent with the master's.
Objections are served within ten days after notice of the filing, stating the grounds for each and the relief sought. The court will not review a question of law dependent on evidence before the master unless the evidence was recorded by a stenographer and the necessary transcript is served with the objections. Other parties may designate additional portions within 10 days.
The court may adopt the report, strike it in whole or part, modify it, recommit it with instructions, or take any other action justice requires. Any motion to adopt a report is deemed to include a motion to enter judgment and must be accompanied by a proposed form of judgment.
Frequently Asked Questions
How do I object to the appointment of a master?
File a written objection with the court within five days of notice of the appointment. Rule 53(b)(4) provides that the grounds shall not be included in the written objection but shall be furnished to the referring justice upon request and in the form the referring justice orders.
What must a master disclose?
Rule 53(b)(5) requires immediate notice to the referring justice if the master is unable or unwilling to serve, bars accepting appointment in any case in which the master cannot be impartial, and requires full written disclosure to the referring justice and all parties, immediately after receipt of the order of reference, of circumstances that may give the appearance of partiality — including any pending matter between the master and a party or a party's counsel.
How does the court treat a master's findings?
In an action tried without a jury the court accepts the master's subsidiary findings unless they are clearly erroneous, mutually inconsistent, unwarranted by the evidence before the master as a matter of law, or otherwise tainted by error of law. The court may draw its own inferences from those subsidiary findings and may make additional findings under Rule 52.
How long do I have to object to a master's report?
Within ten days after service of notice of the filing of the report, or such other time as the court may allow. The objection must clearly state the grounds and the relief sought.
Do I need a transcript to challenge a master's report?
For a question of law dependent on evidence before the master, yes. Rule 53(h)(3) provides that the court will not review such a question unless the evidence was recorded by a stenographer and a transcript of so much of the proceedings as is necessary to dispose of the objections adequately is served, together with the objections, upon every other party.
Does the master show the report to the parties first?
Yes. Rule 53(g)(2) requires the master, at least ten days before filing, to submit a draft to counsel for all parties. Counsel may submit written suggested amendments, with contemporaneous copies to all other counsel, and the master may in discretion allow a hearing on them.
