Summary

The Massachusetts Appeals Court affirmed a lower court's decision to quash a discovery subpoena issued to Dr. Ann Z. Bauer in a case involving Kenvue Brands LLC. The court found the discovery request, related to a California-based lawsuit concerning prenatal acetaminophen use, was not warranted.

What changed

The Massachusetts Appeals Court, in a summary decision pursuant to Rule 23.0, affirmed the lower court's order granting a motion to quash a discovery subpoena against Dr. Ann Z. Bauer. Kenvue Brands LLC had sought discovery from Dr. Bauer, a non-testifying expert and lead author of a paper cited in a California product liability lawsuit against Kenvue. The underlying lawsuit alleges injuries from prenatal acetaminophen use, including risks of ASD and ADHD. The Appeals Court found that the discovery sought was not warranted and upheld the dismissal of Kenvue's action.

This decision primarily impacts the parties involved in this specific discovery dispute. For legal professionals, it serves as a reminder of the limitations on discovery, particularly concerning non-testifying experts and out-of-state proceedings. The non-precedential nature of summary decisions means this ruling has persuasive value but is not binding precedent. No new compliance actions or deadlines are imposed on regulated entities by this court opinion.

Combined Opinion

NOTICE: Summary decisions issued by the Appeals Court pursuant to M.A.C. Rule
23.0, as appearing in 97 Mass. App. Ct. 1017 (2020) (formerly known as rule 1:28,
as amended by 73 Mass. App. Ct. 1001 [2009]), are primarily directed to the parties
and, therefore, may not fully address the facts of the case or the panel's
decisional rationale. Moreover, such decisions are not circulated to the entire
court and, therefore, represent only the views of the panel that decided the case.
A summary decision pursuant to rule 23.0 or rule 1:28 issued after February 25,
2008, may be cited for its persuasive value but, because of the limitations noted
above, not as binding precedent. See Chace v. Curran, 71 Mass. App. Ct. 258, 260

KENVUE BRANDS LLC1

vs.

ANN Z. BAUER.

MEMORANDUM AND ORDER PURSUANT TO RULE 23.0

Kenvue Brands LLC (Kenvue) seeks discovery from a

Massachusetts resident, Dr. Ann Z. Bauer (Bauer), whom the

plaintiffs in a California-based lawsuit consulted as a

nontestifying expert as part of that lawsuit. A judge of the

Suffolk Superior Court issued a subpoena for documents and

testimony from Bauer, and the plaintiffs and Bauer filed a

motion to quash the subpoena. Following a judge's (motion

judge) order granting the motion to quash and denial of Kenvue's

motion for reconsideration, final judgment entered against

1 Formerly known as Johnson & Johnson Consumer Inc.
Kenvue, dismissing this action for discovery; Kenvue appeals.

We affirm.

Background. The case underlying this discovery action was

filed in California by A.D., individually, and as guardian ad

litem for her minor child, M.D., (plaintiffs) against Kenvue.

The plaintiffs alleged that M.D. suffered injuries as a result

of A.D.'s prenatal use of Kenvue's acetaminophen products and

asserted causes of action for strict products liability by

failure to warn, negligence, and breach of "various" implied

warranties. The plaintiffs' claims were based on the central

allegation that Kenvue "owed a duty to [the p]laintiffs to warn

about the risk of prenatal ingestion of acetaminophen,"

including the alleged "risk of [autism spectrum disorder (ASD)]

or [attention-deficit/hyperactivity disorder (ADHD)]." The

complaint relied in part on a paper titled "Paracetamol Use

During Pregnancy -- A Call for Precautionary Action" (Bauer

paper). Kenvue sought discovery from Bauer, who is listed as

the lead author on the Bauer paper.

On August 21, 2024, Kenvue received a commission from a

judge of the California Superior Court in Alameda County to take

an out-of-State deposition of Bauer. A Suffolk Superior Court

judge allowed Kenvue's application for discovery under G. L.

c. 223A, § 11, and issued a subpoena for testimony as well as

for thirty-three requests for production of documents. The

2
plaintiffs and Bauer filed a motion to quash and, alternatively,

for a protective order; Kenvue opposed the motion and filed a

cross motion to compel compliance with the subpoena.2

The motion judge allowed the plaintiffs' motion to quash,

stating that because the plaintiffs contracted with Bauer as a

nontestifying expert "after the California action commenced and

well before this letters rogatory request," discovery of Bauer

must be governed by Mass. R. Civ. P. 26 (b) (4) (B), 365 Mass.

772 (1974) (rule 26 [b] [4] [B]).3 The motion judge concluded

that Kenvue had not demonstrated the existence of "exceptional

During this process, the parties attended a discovery
2

conference in the California Superior Court, and on October 22,
2024, the California judge recommended proceeding with more
limited discovery. Kenvue informed the plaintiffs it would be
willing to proceed with the more limited discovery that the
California judge recommended, and on October 28, 2024, Kenvue
filed a reply in support of its cross motion to compel
compliance with the subpoena in the Suffolk Superior Court,
informing the motion judge of the more limited discovery
recommendation. Kenvue did not, however, limit the scope of its
motion to compel.

3 The motion judge cited to the rule for the proposition
that

"discovery of the facts known and opinions held by an
expert who has been . . . 'specifically employed by another
party in anticipation of litigation or preparation for
trial and who is not expected to be called as a witness at
trial . . . [may only be obtained] upon a showing of
exceptional circumstances under which it is impracticable
for the subject party seeking discovery to obtain facts and
opinions by the same subject by other means.'"

3
circumstances" and found that Kenvue could likely obtain the

information it sought by other means.

Additionally, the motion judge concluded that even if

Kenvue "could show exceptional circumstances warranting [the]

discovery from Bauer," that it was an "undue hardship for

[Bauer] to be deposed" at that time because she reported that

she provides daily care for her seriously ill husband.

Following the motion judge's allowance of the motion to quash,

final judgment entered against Kenvue dismissing this discovery

action. Kenvue appeals from the final judgment.

Discussion. While Kenvue challenges both grounds of the

motion judge's ruling -- the motion judge's determination that

the request was unduly burdensome on Bauer and the motion

judge's interpretation and application of rule 26 (b) (4) (B)4 --

we conclude that the motion judge did not abuse her discretion

in determining that the discovery requests were unduly

burdensome. See Commissioner of Revenue v. Comcast Corp., 453

Mass. 293, 302 (2009) ("In general, we uphold discovery rulings

unless the appellant can demonstrate an abuse of discretion that

resulted in prejudicial error" [quotation and citation

omitted]). Thus, we need not and do not reach whether the

4 Kenvue also contests the finding that it could likely
obtain the information it sought by other means, arguing that it
seeks information that is not otherwise available.

4
motion judge's determination that its discovery request was

governed by rule 26 (b) (4) (B) was an error of law.

"It is within [the] court's power to vacate any subpoena

which it determines is unreasonable, oppressive, irrelevant, or

improper." Hull Mun. Lighting Plant v. Massachusetts Mun.

Wholesale Elec. Co., 414 Mass. 609, 616 (1993), citing Mass.

R. Civ. P. 45 (b), as appearing in 470 Mass. 1402 (2015) (rule

45 [b]). Rule 45 (b) "allows a witness for whom such production

would be unreasonably burdensome to move to quash the subpoena,

thereby avoiding any such duty in cases where it would be

unreasonable or oppressive to impose it." Fletcher v.

Dorchester Mut. Ins. Co., 437 Mass. 544, 549 n.10 (2002). The

parties agree that at the time this discovery was sought, Bauer

was the full-time caregiver for her husband following an

accident in March 2024. The motion judge was persuaded that

requiring Bauer to participate in discovery when she had full-

time caregiver responsibilities was an undue hardship, and an

independent reason to quash the subpoena. Our standard of

review is deferential to the motion judge's assessment. See

L.L. v. Commonwealth, 470 Mass. 169, 185 n.27 (2014). Because

we conclude that the motion judge's determination and the

subsequent quashing of the subpoena were within "the range of

reasonable alternatives," id., we conclude that the order

5
allowing the motion to quash did not constitute an abuse of

discretion.5

Judgment affirmed.

Allen, JJ.6),

their appellate costs pursuant to Mass. R. A. P. 26 (a), as
appearing in 481 Mass. 1655 (2019).
