19 The Protective Order negotiated by the parties includes a provision authorizing them
20 to redact information produced in discovery “that is objectively irrelevant to this Action.”
21 The issue is whether the Protective Order should be amended to remove this provision.
22 I.
23 BACKGROUND
24 A. Plaintiff’s Amended Complaint
25 Plaintiff brings this putative class action against Defendant Mercedes-Benz USA,
26 LLC (and two defendants that have not yet appeared in the case) on behalf of persons who
27 purchased Mercedes-Benz S-Class vehicles of model years 2021 through 2024 (the “Class
28 Vehicles”) in California. Dkt. No. 140 ¶ 1 (Amended Complaint). The Class Vehicles
1 allegedly have “materially defective wheels and tires,” i.e., the “Wheel Configuration
2 Defect,” (id.), which causes premature tire failure and frequent tire blowouts. Id. ¶¶ 27, 46-
3 55. Plaintiff asserts that Defendant had knowledge of this defect and failed to take
4 corrective action. Id. ¶¶ 6, 74-80.
5 Plaintiff brings claims for: (1) violations of California’s Song-Beverly Consumer
6 Warranty Act; (2) violations of California’s Unfair Competition Law; (3) breach of express
7 warranty; (4) breach of implied warranty; (5) unjust enrichment; and (6) fraudulent
8 concealment. Id. ¶¶ 128-222.
9 B. The Protective Order
10 In April 2025, the Court granted the parties’ joint motion for entry of a protective
11 order and issued their proposed Protective Order governing discovery in this case. Dkt.
12 No. 34. The Protective Order contains the following provisions that are relevant to this
13 motion:
14 The Parties recognize that there may be portions of documents and
15 attachments that will be captured by searches, but that may not be relevant to
16 any party’s claims or defenses. Therefore, the Parties are not prohibited from
17 redacting information that is objectively irrelevant to this Action.
18 . . . .
19 The Court may modify the terms and conditions of this Order for good cause,
20 or in the interest of justice, or on its own order at any time in these
21 proceedings.
22 Id. at 4, 11.
23 Both parties have redacted documents produced in discovery. Plaintiff has redacted
24 portions of four responsive documents. Dkt. No. 165-4 at 3. Defendant has redacted a
25 larger number of responsive documents as reflected in its 27-page “relevance redaction
26 log.” Dkt. No. 165-3. As explained by Defendant’s counsel at the motion hearing on
27 December 11, 2025, the redacted information includes (1) information pertaining to non-
28 class vehicles; (2) information pertaining to S-Class vehicles sold outside California;
1 (3) information pertaining to vehicle parts other than wheels, rims and tires; and
2 (4) information pertaining to tire and wheel issues with Class Vehicles where the dealers
3 performing the repairs determined that any damage was caused by road hazards.
4 II.
5 LEGAL STANDARDS
6 “The court may, for good cause, issue an order to protect a party or person from
7 annoyance, embarrassment, oppression, or undue burden or expense.” Fed. R. Civ. P.
8 26(c)(1). “The burden is upon the party seeking the order to show good cause by
9 demonstrating harm or prejudice that will result from the discovery.” Ribera v. NIBCO,
10 Inc., 364 F.3d 1057, 1063 (9th Cir. 2004). Similarly, a party seeking to modify an existing
11 protective order ordinarily “bears the burden of proving such good cause exists to modify
12 the protective order.” In re Soc. Media Adolescent Addiction/Pers. Inj. Prods. Liab. Litig.,
13 No. 22-MD-03047-YGR (PHK), 2024 WL 251404, at *8 (N.D. Cal. Jan. 23, 2024).1
14 The analysis differs where the parties stipulate to a protective order. “While courts
15 generally make a finding of good cause before issuing a protective order, a court need not
16 do so where (as here) the parties stipulate to such an order.” In re Roman Cath. Archbishop
17 of Portland in Or., 661 F.3d 417, 424 (9th Cir. 2011). “When the protective order was a
18 stipulated order and no party has made a good cause showing, then the burden of proof
19 remains with the party seeking protection.” Id. For example, “if a party takes steps to
20 release documents subject to a stipulated order, the party opposing disclosure has the
21 burden of establishing that there is good cause to continue the protection of the discovery
22 material.” Id.

2 DISCUSSION
3 As an initial matter, the parties dispute which of them bears the burden on this
4 motion. Plaintiff contends that Defendant must show good cause to maintain the provision
5 authorizing redaction of “objectively irrelevant” information. Defendant counters that
6 Plaintiff must show good cause to modify the Protective Order by removing the provision.
7 The parties stipulated to the Protective Order, and neither party made a good cause
8 showing for any provision, including the provision authorizing redactions. See Dkt. No.
9 33. Nor did the Court make a good cause finding prior to adopting the stipulated Protective
10 Order. See Dkt. No. 34. Thus, the principles articulated in In re Roman Cath. Archbishop
11 of Portland in Or. apply here, and Defendant carries the burden of establishing good cause
12 for the redaction provision because it is “the party seeking protection.” Id. See Foltz v.
13 State Farm Mut. Auto. Ins. Co., 331 F.3d 1122, 1131 (9th Cir. 2003) (where third party
14 intervenors sought documents produced in discovery by State Farm and designated
15 pursuant to stipulated protective order, “the district court must require State Farm to make
16 an actual showing of good cause for their continuing protection under Federal Rule of Civil
17 Procedure 26(c)”).
18 “Courts generally disfavor redacting responsive documents for relevancy, since such
19 concerns can be addressed by a protective order.” Ho v. Marathon Pat. Grp., Inc., No.
20 521CV00339SSSSPX, 2023 WL 3044613, at *4 (C.D. Cal. Mar. 27, 2023). See Rodriguez
21 v. Vizio, Inc., No. 14-CV-368 JLS (NLS), 2015 WL 11439029, at *4 (S.D. Cal. Jan. 6,
22 2015) (ordering production of unredacted document and concluding that protective order
23 adequately addressed producing party’s “confidentiality concerns”); Laub v.
24 Horbaczewski, 331 F.R.D. 516, 526 (C.D. Cal. 2019) (“a party should not take it upon him,
25 her or itself to decide unilaterally what context is necessary for the non-redacted part
26 disclosed, and what might be useless to the case”). In addition, “unilateral redactions do
27 little more than breed suspicion between the parties, generate discovery disputes, and invite
28 unnecessary intervention by the court.” Canchola v. Allstate Ins. Co., No. 8:23-CV-00734
1 FWS (ADSX), 2025 WL 2373272, at *2 (C.D. Cal. July 11, 2025). Even where the party
2 making unilateral redactions acts “with restraint and in good faith,” the problems caused
3 by such redactions may “outweigh the minimal risk of harm that may result from disclosure
4 of some irrelevant or private material pursuant to a protective order.” Leprino Foods Co.
5 v. Avani Outpatient Surgical Ctr., Inc., No. 2:22-CV-07434-DSF-JC, 2024 WL 4488711,
6 at *14 (C.D. Cal. Sept. 30, 2024). At least one other court has adopted this reasoning and
7 rejected Mercedes-Benz USA’s proposal for unilateral relevance redactions in discovery.
8 Sowa v. Mercedes-Benz Grp. AG, No. 1:23-CV-636-SEG, 2025 WL 3143639, at *7-8
9 (N.D. Ga. Nov. 3, 2025) (redactions of “objectively irrelevant” information “undermine
10 the aims of the discovery process” and “would likely open the door to more discovery
11 dispute litigation and time-consuming requests for in camera review”).
12 Here, Defendant does not explain why the Protective Order’s provisions authorizing
13 the parties to designate materials as “Confidential” or “Confidential – For Counsel Only”
14 are insufficient to protect any sensitive business information. See Dkt. No. 34.2 And
15 although the Court does not question Defendant’s good faith in making redaction
16 determinations, its explanation of the information it considers “objectively irrelevant” to
17 Plaintiff’s claims demonstrates that this provision is unworkable in the context of this case.
18 “Evidence is relevant if: (a) it has any tendency to make a fact more or less probable
19 than it would be without the evidence; and (b) the fact is of consequence in determining
20 the action.” Fed. R. Evid. 401. For example, evidence that 2021-2024 S-Class vehicles
21 experienced unexplained tire blowouts or failures would be relevant to Plaintiff’s claims
22
23
2 The Court is mindful that the parties negotiated the provision authorizing relevance
24
redactions and that Defendant agreed to modify this District’s model protective order
25 provision regarding expert review of documents designated as “Confidential – For Counsel
Only” in exchange for Plaintiff’s agreement to include the relevance redaction provision.
26
Dkt. No. 165-1 at 2. However, in ruling on this motion, the Court’s determination is limited
27 to whether Defendant has established good cause for the relevance redaction provision, and
nothing in this Order prevents either party from seeking to modify any other provision of
28
1 irrespective of whether the vehicles were purchased in California or another state. But
2 Defendant’s contrary position that such information is “objectively irrelevant” to Plaintiff’s
3 claims would deprive Plaintiff of this information. It does not matter whether such
4 information would be admissible at trial – which is an issue to be determined by the District
5 Judge – because information “need not be admissible in evidence to be discoverable.” Fed.
6 R. Civ. P. 26(b)(1).
7 Defendant’s redaction of information pertaining to Class Vehicles where the dealers
8 determined that any wheel or tire damage was caused by road hazards raises similar
9 concerns. It may be true that Plaintiff “does not allege her tires were damaged by impact
10 or road hazards.” Dkt. No. 21 at 11 n. 1. However, it does not follow that a third-party
11 dealer’s determination that a tire was damaged by a road hazard renders that information
12 “objectively irrelevant” to Plaintiff’s claims. After all, relevant evidence “has any
13 tendency to make a fact more or less probable that it would be without the evidence.” Fed.
14 R. Evid. 401(a) (emphasis added). A dealer’s determination that a Class Vehicle sustained
15 tire damage due to a road hazard (as opposed to a design defect) may not support Plaintiff’s
16 theory of the case, but it is still relevant under Rule 401(a).
17 Defendant cites authority for the proposition that unilateral redactions may be
18 appropriate where the redacted information “plainly has no substantive bearing on the
19 claims and defenses in th[e] action.” Found. for Glob. Sports Dev. v. United States Olympic
20 Comm., No. 220CV04782FMOPVCX, 2021 WL 6618556, at *10 (C.D. Cal. June 24,
21 2021) (upholding redactions of responding party’s board minutes showing its “litigation
22 costs in an unrelated matter”). But even that case endorsed the proposition that the
23 “unilateral redaction of documents on the ground that the producing party deems the
24 information irrelevant is generally improper” and that redactions would be appropriate only
25 where the information “plainly has no potential relevancy to the litigation or is particularly
26 sensitive.” Id. at *9. As explained above, the Court cannot conclude that the information
27 Defendant elected to redact has “no potential relevancy to the litigation,” and Defendant
28 does not explain how the Protective Order’s other provisions do not adequately address
1 || concerns about production of sensitive information.
2 IV.
3 CONCLUSION
4 For the foregoing reasons, the Court grants Plaintiff's motion to amend the
5 || Protective Order and will concurrently issue an Amended Protective Order. By not later
6 ||than January 27, 2026, each party must produce unredacted versions of any documents
7 || previously produced with redactions for relevancy.
