Sealing Records and Protective Orders in California Employment Suits
“Unless confidentiality is required by law, court records are presumed to be open.” That rule of court is why California employers can’t keep documents out of the public file just by stamping them confidential. A stipulated protective order can control how sensitive discovery is shared. But once a document is filed to support a motion or used at trial, sealing it requires a court order with specific findings under rules 2.550 and 2.551. Employers that plan for that difference protect far more information.
What’s the difference between a protective order and sealing?
They cover different stages of the case. A protective order governs discovery: who can see documents produced between the parties, how they’re marked, and what happens to them at the end. The sealing rules govern what’s filed with the court. California Rules of Court, rule 2.550(a)(3) says the sealing rules “do not apply to discovery motions and records filed or lodged in connection with discovery motions or proceedings.”
The same subdivision adds the turn that catches employers off guard: the rules “do apply to discovery materials that are used at trial or submitted as a basis for adjudication of matters other than discovery motions or proceedings.” A personnel file produced under a protective order is protected in discovery. The same file attached to a summary judgment motion is presumptively public unless the court seals it.
What does a court have to find to seal a record?
Five things, expressly. Under rule 2.550(d), the court may order a record sealed “only if it expressly finds facts that establish” that an overriding interest overcomes the right of public access, that the interest supports sealing, and that a substantial probability of prejudice exists if the record isn’t sealed. The rule also requires findings that the proposed sealing “is narrowly tailored” and that “No less restrictive means exist to achieve the overriding interest.”
The order itself has to be specific. It must “Specifically state the facts that support the findings,” and direct sealing of only the documents and pages, or portions of them, that contain the protected material. Everything else on those pages goes in the public file.
The standard comes from the Supreme Court of California’s decision in NBC Subsidiary (KNBC-TV), Inc. v. Superior Court (1999), as the Judicial Council’s advisory comment to the rule explains. In practice, it means a motion to seal needs evidence, usually a declaration explaining what the information is and what harm disclosure would cause, not a general claim that the documents are confidential.
What employer information can usually be protected?
Information with a concrete harm attached. Courts commonly recognize interests in trade secrets and confidential business information that’s actually kept secret, in the privacy of third parties, and in some medical information. In employment cases, the categories that come up most are:
Other employees’ personnel files, pay, and discipline records, which carry privacy interests for people who aren’t parties.
Medical and leave records, both the plaintiff’s and coworkers’.
Customer lists, pricing, and other trade secret material, often at issue when the employee also faces claims about departing with confidential information.
Investigation reports naming complainants and witnesses, where disclosure could discourage future reporting.
An employer’s own embarrassment, or a desire to keep the allegations out of the news, usually isn’t enough.
The declaration supporting the motion carries the weight. It should come from someone with personal knowledge, like the head of HR or the business unit that owns the data, and explain what the information is, how the company keeps it confidential, and what specific harm would follow from disclosure. A declaration that repeats the five findings in the rule’s own words, without facts, tends to fail. Courts also look at whether the information is already public, whether it’s stale, and whether the employer has treated it as confidential outside the lawsuit. Pricing from five years ago, or a policy posted in every break room, is hard to seal. Courts expect the employer to redact, not seal whole documents, and to explain why redaction alone won’t protect the interest.
| Information | Protective order in discovery | Sealing when filed |
|---|---|---|
| Non-party personnel and pay data | Commonly allowed, often with redaction of identifiers | Usually limited to identifiers and private details |
| Medical records | Commonly allowed | Often sealed or redacted with a supporting declaration |
| Trade secrets and pricing | Commonly allowed, sometimes attorneys’-eyes-only | Possible with specific evidence of competitive harm |
| The plaintiff’s allegations and the employer’s general policies | Rarely needed | Rarely sealed |
How does the procedure work?
A party moves to seal and lodges the material conditionally under seal, following rule 2.551. A common problem in employment cases is that the plaintiff wants to file a document the employer designated confidential. Rule 2.551 has a procedure for that situation, in which the filing party lodges the material conditionally and the designating party must then move to seal it within the time the rule sets. An employer that misses that window can lose the protection.
That makes the protective order’s drafting important. A well-built stipulated order describes how designated material will be handled at the filing stage, gives the designating party notice, and doesn’t promise that anything will automatically be sealed, because the court still has to make the findings. The order should also deal with depositions, inadvertent production, and what happens to the material when the case ends. Return-or-destroy provisions at the end of the case matter most when the plaintiff is a former manager who may go to work for a competitor.
Discovery protective orders themselves come from the Code of Civil Procedure. For document requests, section 2031.060 lets a party move for a protective order for good cause, which is a lower bar than the sealing findings.
Does a confidential settlement keep the case private?
Partly, and with limits. Settlement terms can be kept confidential by agreement, but the court file up to that point is usually public. California also limits confidentiality provisions in settlements of some claims, including certain harassment and discrimination claims. The firm’s post on confidential sexual harassment settlements under CCP 1001 covers those limits.
When confidential documents are about to be produced
- Put the personnel, payroll, medical, and investigation files at issue under a litigation hold, along with the emails and texts that discuss them.
- Calendar the discovery response dates, and check for an arbitration agreement, which can keep many filings out of the public court file, and an EPLI policy with notice terms.
- Identify the non-party employees whose records may be produced, and the managers whose files contain trade secrets or sensitive data.
- Sort the documents into tiers: information that can be produced openly, information needing a confidential designation, and information needing redaction before production.
- Have counsel negotiate a stipulated protective order before production, with a filing procedure that gives the company notice and time to move to seal.
Confidentiality fights are a recurring part of defending employment cases. The firm’s page on California employment defense describes how those cases are handled.
Sealing and protective order questions
Can we refuse to produce other employees’ personnel files?
Not always. California courts balance the non-party employees’ privacy against the plaintiff’s need for the records. Comparator files are often ordered produced in discrimination cases, typically with redactions and a protective order. Employers usually do better proposing limits, like redacting identifying details or producing only relevant sections, than refusing outright. Non-party notice may also be required for some records.
Does marking a document confidential keep it out of the public record?
No. A confidential designation under a protective order controls how the parties handle the document. It doesn’t bind the court. When the document is filed in support of a motion, the sealing rules apply, and the court decides whether to seal based on findings. A designation without a timely motion to seal often means the document ends up in the public file.
Can the whole case be filed under seal?
Almost never. Court records are presumed open, and sealing must be narrowly tailored to specific material. Courts expect parties to redact names or details where that’s enough. Plaintiffs sometimes proceed under a pseudonym in sensitive cases, but that’s a separate request with its own standard, and it doesn’t make the employer’s filings confidential.
Does arbitration keep the dispute confidential?
Arbitration proceedings aren’t public court records, so they usually stay out of the public file. Confidentiality depends on the arbitration agreement and the provider’s rules, and it may be challenged. Any court proceedings around the arbitration, like a motion to compel or to confirm an award, can put material in the public record.
If sensitive company records are at stake in a lawsuit
If your company is defending an employment case that will require producing personnel, medical, or trade secret information, the protective order and the sealing strategy should be set before the first production.
