Appointing Discovery Referees in California Courts
Understand when, why, and how California courts appoint discovery referees, and how lawyers can effectively navigate the process.
Complex discovery fights can overwhelm California civil courts and drive up litigation costs. In these cases, judges may turn to a discovery referee—a neutral attorney, judge, or retired justice—tasked with managing and deciding discovery disputes under the authority of California’s reference statutes and court rules.
This guide explains the legal framework for appointing a discovery referee, how the process works in practice, and what California litigators should consider strategically when agreeing to or opposing such an appointment.
1. What Is a Discovery Referee?
A discovery referee is a neutral person appointed under the California Code of Civil Procedure’s reference provisions to oversee discovery, resolve disputes, and report to the court. The referee may be authorized to:
- Hear and decide motions to compel, protective orders, and sanctions
- Manage schedules for written discovery, document production, and depositions
- Conduct hearings, take evidence, and issue written recommendations or decisions
- Report findings and recommendations back to the appointing judge
Discovery references in California are governed principally by:
- Code of Civil Procedure (CCP) sections 638–645.1 (general and special references, including discovery)
- California Rules of Court, rules 3.900–3.932 (procedural rules on reference appointments, including discovery referees)
2. Legal Framework: General vs. Special References
California distinguishes between general references and special references when a referee is appointed. Discovery referees can be appointed under either structure, depending on the parties’ agreement and the court’s order.
| Feature | General Reference (CCP 638(a)) | Special Reference (CCP 638(b) / 639) |
|---|---|---|
| Typical basis | Written stipulation or contract requiring reference | Court order (often without prior agreement of all parties) |
| Effect of referee’s decision | Becomes the court’s decision or judgment, subject to very limited review | Advisory; court may accept, modify, or reject recommendations |
| Common use in discovery | Highly trusted neutral given near-arbitral authority over discovery | Most common for discovery disputes under CCP 639(a)(5) |
| Degree of court oversight | Lower—referee functions almost as a trial court for the referenced issues | Higher—judge reviews referee’s recommendations before entering orders |

3. Statutory Authority for Discovery Referees
Several provisions in the Code of Civil Procedure specifically authorize appointment of discovery referees:
- CCP § 639(a)(5): Allows a court to appoint a referee when it determines such appointment is necessary to hear and determine discovery motions and disputes and to report findings and recommendations.
- CCP § 638: Enables appointment of a referee by stipulation or contract to decide issues, including discovery, in a general or special reference.
- CCP § 643–645.1: Address the referee’s reports, objections, review by the court, and compensation.
The California Rules of Court elaborate on these statutory provisions, requiring that both the motion and the order appointing a discovery referee meet detailed content and notice requirements.
4. When Courts Use Discovery Referees
California courts are instructed to use discovery referees under CCP § 639(a)(5) only in exceptional circumstances because they shift some of the cost of judicial management to the parties and can significantly affect case strategy.
Examples of situations where courts often consider a referee include:
- Cases with numerous discovery motions or a pattern of ongoing disputes
- Large document-intensive matters (e.g., complex commercial, class action, or construction cases)
- Multi-party litigation where coordinating discovery is unusually burdensome
- Situations where discovery rulings require extensive evidentiary hearings or expert input
- Matters where using regular law-and-motion calendars would cause significant delay
In smaller or routine cases, judges generally manage discovery disputes directly without appointing a referee, in keeping with the presumption that court supervision remains the default.
5. Paths to Appointment: Agreement vs. Court Order
5.1 Appointment by Agreement (Stipulated Reference)
Parties may voluntarily agree to use a discovery referee under CCP § 638. That agreement may arise from:
- A pre-dispute contract clause calling for reference of discovery issues
- A post-filing stipulation signed by all parties
In stipulated references:
- The parties can jointly choose the referee (often a retired judge or experienced litigator)
- They may negotiate the scope of authority—for example, limiting the referee to discovery disputes relating to electronically stored information (ESI)
- The appointment can be tailored to timing, procedure, and reporting format
5.2 Appointment by Court Order (Contested or Sua Sponte)
Under CCP § 639, a court may appoint a discovery referee:
- On motion of any party requesting a referee
- On the court’s own motion (sua sponte), even over one party’s objection, if statutory criteria are satisfied
When the appointment is made under § 639(a)(5), the court must make written findings that the case presents exceptional circumstances requiring reference, and must spell out the referee’s authority, subject matter, and compensation arrangements in the order.
6. Requirements for the Appointment Order
California Rule of Court 3.922 requires that an order appointing a referee be in writing and include key elements so that its scope and terms are clear to the parties and the referee.
For discovery referees appointed under CCP § 639(a)(5), the order must, at a minimum:
- Identify the legal basis for the appointment (e.g., CCP § 639(a)(5))
- State the exceptional circumstances that make the appointment necessary
- Specify whether the reference covers all discovery or only defined issues or motions
- Describe the referee’s authority, including power to:
- Set hearings
- Issue subpoenas
- Take evidence
- Rule on objections and motions during hearings
- Address compensation, including hourly rates and allocation of payment responsibilities among the parties
- Explain how the referee is to report to the court (written recommendations, proposed orders, timelines)
Clear orders reduce the risk of challenges later, particularly appellate attacks claiming that the court improperly delegated judicial functions or failed to comply with procedural protections.
7. Scope of Authority and Court Review
Discovery referees do not replace the court; they act under delegated authority defined by the order of appointment and the governing statutes.
Depending on the type of reference:
- In a general reference under CCP § 638(a), the referee’s statement of decision effectively becomes the court’s decision once accepted and entered, with limited judicial review.
- In a special reference or a § 639(a)(5) appointment, the referee typically issues an advisory report; the trial judge can adopt, modify, or reject the recommendations.
California law requires a process for objections and review:
- Parties may file objections to the referee’s recommendations or proposed order within a specified time period (often governed by local rules or the appointment order)
- The court then conducts a review of the record before ruling on those objections and entering its own order
Counsel should treat hearings before a discovery referee as seriously as appearances before the trial judge, ensuring a complete record, precise briefing, and clear argument tailored to potential later review.
8. Practical Pros and Cons for Litigators
The decision to consent to, request, or oppose a discovery referee depends heavily on case-specific factors.
8.1 Potential Advantages
- Speed: Referees often provide faster hearing dates and decisions than crowded civil law-and-motion calendars, which can be critical in discovery-heavy cases.
- Expertise: Many referees are former judges or senior litigators with deep discovery and e-discovery experience, which can lead to more tailored and pragmatic rulings.
- Continuity: A single neutral following all discovery disputes can better understand the history of the case and the parties’ conduct.
- Process flexibility: Referees may permit informal conferences, rolling briefing, or customized protocols that are harder to arrange through standard court procedures.
8.2 Potential Disadvantages
- Cost: Referees are privately compensated, and their fees are typically paid by the parties in proportions set by the court’s order. This can be significant in lengthy or contentious matters.
- Additional procedural layer: Parties may have to brief issues twice—once to the referee and again when challenging or defending the referee’s recommendations before the judge.
- Perception of inequality: Differences in resources among parties may affect how comfortably each side can engage with an intensive discovery reference process.
9. Strategic Considerations Before You Stipulate
Before agreeing to appoint a discovery referee, counsel should consider:
- Case size and stakes
Is the amount in controversy high enough to justify additional fees? - Expected volume of discovery
Are there multiple parties, large ESI collections, or complex privilege issues? - Existing judicial bandwidth
Is the assigned judge already signaling difficulty in managing discovery timing? - Choice of neutral
Does the proposed referee have relevant experience, reputation for fairness, and availability? - Allocation of costs
Can you negotiate a fair cost-sharing arrangement or protections for clients with limited resources? - Review standard
Are you comfortable with the level of judicial review that applies under the proposed reference structure?
10. Best Practices for Working with a Discovery Referee
Once a referee is appointed, effective advocacy requires both procedural discipline and strategic planning.
- Clarify the procedural roadmap early
At the first conference, seek clarity on briefing schedules, page limits, format of evidence, and expectations for meet-and-confer efforts. - Invest in the record
Even if the referee’s decision is advisory, assemble a record that will withstand court review: complete exhibits, clear privilege logs, and precise declarations. - Use targeted motions
A referee can handle nuanced or staged relief (e.g., sampling, phased production), so tailor your asks to what is genuinely necessary. - Maintain professionalism
Referees often report not only on legal rulings but on the parties’ cooperation and credibility; this can indirectly influence the trial court. - Monitor costs
Track time spent on referee proceedings and be prepared to address fee allocation or cost-shifting as appropriate.
11. Common Misconceptions
- “Using a referee means the judge won’t be involved.”
Even in broad discovery references, the trial court retains ultimate authority, especially in special references where recommendations are advisory. - “Referees always side with the requesting party.”
Referees are bound by the same statutes and case law as courts. Their reputations depend on neutrality and sound reasoning. - “Appointment is automatic in large cases.”
Rule 3.920(c) makes clear that appointment under § 639(a)(5) is reserved for exceptional circumstances, not mere size or complexity alone.
Frequently Asked Questions (FAQs)
Q1: Is a discovery referee the same as an arbitrator?
No. An arbitrator typically issues a binding award that is enforceable like a judgment, while a discovery referee works within a pending court case and is subject to the court’s supervision and review under the reference statutes.
Q2: Who pays for a discovery referee in California?
The order of appointment usually specifies how the referee’s fees are allocated. Courts may divide costs equally, apportion them based on the parties’ relative resources, or shift fees as a sanction under discovery rules where justified.
Q3: Can a party object to the appointment of a discovery referee?
Yes. When appointment is sought under CCP § 639, parties may oppose the motion or object to a court-initiated appointment, arguing that the statutory standard of necessity and exceptional circumstances is not met. Ultimately, the trial court decides whether to appoint a referee.
Q4: How quickly must a discovery referee issue a decision?
California law and many appointment orders require timely decisions. In practice, referees often issue written recommendations on an accelerated schedule compared with standard law-and-motion calendars, and the parties may stipulate to specific timelines in the order of appointment.
Q5: Are the referee’s recommendations appealable?
Discovery rulings are usually reviewed first by the trial court through objections to the referee’s report. Direct appellate review is limited and generally occurs only after a final judgment, though extraordinary writ relief may be sought in rare circumstances.
