IN THE UNITED STATES DISTRICT COURT
FOR THE EASTERN DISTRICT OF PENNSYLVANIA

IN RE: DOMESTIC DRYWALL
ANTITRUST LITIGATION CIVIL ACTION

HOME DEPOT U.S.A., INC. MDL No. 13-2437

v. Case No. 18-cv-5305

LAFARGE NORTH AMERICA INC.

MEMORANDUM RE: MOTION FOR CERTIFICATION FOR
INTERLOCUTORY APPEAL

Baylson, J. November 5, 2021
Plaintiff, Home Depot U.S.A., Inc. (“Home Depot”), filed a Motion for Certification under
28 U.S.C. § 1292(b). (ECF. No. 142). Home Depot requests this Court certify for appeal its
August 20, 2021 Order—which granted Defendant Lafarge North America, Inc.’s (“Lafarge”)
Daubert motion to exclude an economic expert retained by Home Depot—so Home Depot may
petition the Third Circuit Court of Appeals for permission to appeal.
I. BACKGROUND

This Court’s Memorandum & Order (ECF No. 136) fully sets forth the factual background
and the reasons upon which this Court relied to justify its exclusion of Dr. Kneuper as Home
Depot’s expert economist. The rulings this Court made in its Order will not be repeated because
they are well stated in the Memorandum Opinion (ECF No. 136), and the present Motion filed by
Home Depot (ECF No. 142), Lafarge’s Response (ECF No. 143), and Home Depot’s Reply Brief
(ECF No. 144) accurately describe the unique procedural history.
Briefly though, this Court excluded Home Depot’s for several reasons, two of which were:
(i) because Dr. Robert Kneuper improperly based his expert opinions on conclusions that were
contrary to findings and rulings this Court had made earlier in this multidistrict litigation; and (ii)
because he relied on facts that were not established in the prior proceedings, and in some instances
on facts that were contrary to other established facts. Although Dr. Kneuper’s ultimate conclusions
superficially appeared to be the usual and normal opinions of an economist appearing for a plaintiff

in an antitrust case, the reasons he gave for these conclusions took him out of the realm of
economics, and as this Court noted in its Memorandum Opinion, Dr. Kneuper turned himself into
a “attorney-juror-judge.”
The litigation history of this case is relevant. Home Depot had been a class member
participating in a large settlement which was finalized before Home Depot filed its complaint in
the Northern District of Georgia on June 11, 2018. Home Depot opted out of this class, but only
did so as to Lafarge only; it remained apart of the class as to all the remaining defendants. Then,
Home Depot filed the present action against Lafarge, and it was transferred to the undersigned by
the Judicial Panel of Multidistrict Litigation (“JPML”) on December 10, 2018. Once this case was
transferred to this Court, Home Depot did very little, and nothing of significance, to initiate any
discovery of its own although there was no bar to it doing so. 1

As stated in its Memorandum Opinion, there is little if any precedent for the Court’s
decision to rely on its prior rulings in this MDL to strike Dr. Kneuper’s expert opinions. Although
this Court disagrees with Home Depot’s argument that its Order was incorrect2, Home Depot does

1 Home Depot did not initiate any discovery to secure facts that Georgia Pacific, U.S. Gypsum,
and CertainTeed were members of the conspiracy. Strategically, it is possible Home Depot did
not seek this discovery because it decided it could use Dr. Kneuper’s report to assume facts about
these three entities, without going through the expense of actually presenting facts to allow this
Court to make such an inference.

2 See Multidistrict Litig. Man. § 9:3, Status of transferor court rulings (“The Panel [] recognizes
that orders made in one of the transferred cases may be made applicable to other parties and actions
by the transferee judge.”).
correctly recognize the novelty of this Court’s Order, particularly within the context of
multidistrict antitrust litigation (“MDL”). Home Depot is also correct that the issues decided by
this Court were controlling issues of law, that substantial ground for difference of opinion on those
issues exists, and that an appellate decision will likely advance the termination of this litigation.

For the foregoing reasons, Home Depot’s Motion will be GRANTED.
II. DISCUSSION

28 U.S.C. § 1292(b) sets out a three-part test for certification for interlocutory appeal:

(1) Whether the motion to be appealed involves a controlling question of law;
(2) Whether there is a substantial ground for the difference of opinion with respect
to resolution of the issue to be appealed; and
(3) Whether an immediate appeal from the district court’s decision could materially
advance the ultimate termination of the litigation.

28 U.S.C. § 1292(b).
A. The Court’s Order Decided a Controlling Question of Law
This Court decided an issue that is a controlling issue of law in this litigation: that Home
Depot is bound by the rulings this Court made before Home Depot’s present action was transferred
to this Court.
First, the Court relied on principles of “issue-preclusion” and “law of the case” to justify
its conclusion that Home Depot, and its expert economist Dr. Kneuper, were bound by rulings
entered in this MDL before Home Depot’s case was transferred to this Court in 2018. Whether
Home Depot is indeed bound by rulings issued in this MDL before Home Depot joined it in 2018,
as this Court held it was, is one issue that will absolutely control future proceedings in this case.
Home Depot argues this Court’s rulings that were issued before Home Depot transferred
into this MDL should not apply, and accordingly, that this Court had no right to rely on principles
of “issue preclusion” and “law of the case” when ruling on the Dr. Kneuper Daubert motion.
Home Depot is correct that this Court relied extensively on these two legal principles when it
excluded Dr. Kneuper. Both “issue preclusion” and “law of the case” principles can play an
important role in traditional pretrial proceedings in complex commercial litigation, and this is
especially true when courts decide important issues during those proceedings.

Although this Court believes it had the right to rely on principles of “issue preclusion” and
“law of the case”, for the reasons set forth in its Memorandum Opinion, this Court’s Order decided
this controlling issue of law and which will directly affect the trajectory of this case. This Court’s
Order will affect both the upcoming decision on Lafarge’s pending Motion for Summary Judgment
(ECF No. 82) and the proceedings after this case is transferred back to the Northern District of
Georgia for trial.3 Once this case is returned to the Northern District of Georgia after the
conclusion of pretrial proceedings, the trial judge may be bound by this Court’s rulings.4 The
judge to whom this case will be assigned for trial will be totally unfamiliar with the extensive
procedural history, but will undoubtedly be affected, if not affirmatively bound, by this Court’s
various rulings. As a practical matter, it is unlikely that the judge to whom the case is assigned in

the Northern District of Georgia will undertake a completely de novo examination of the
procedural history and this Court’s rulings. So, this Court’s Order will continue to direct impact
the case after it leaves this Court.
Therefore, the principal controlling question of law is whether a tag-along party’s expert

3 This case must be returned to the Northern District of Georgia once pretrial proceedings are
completed in this Court. Lexecon, Inc. v. Milberg Weiss Bershad Hynes & Levach, 523 U.S. 26
(1998).

4 See Multidistrict Litig. Man. § 9:3, Status of transferor court rulings (“The transferor court’s
orders are not treated as law of the case. They may be reviewed by the transferee court [under the
highly deferential standards of the law of the case doctrine]. In this regard, the transferee court is
given somewhat broader powers than the transferor court, for the transferor court is bound, upon
remand, by the orders entered by the transferee court during the coordinated or consolidated
pretrial proceedings. Those decisions are considered law of the case.”) (emphasis added).
may ignore prior rulings that were issued by the MDL transferee judge before the tag-along party
joined said MDL? This question is not raised by normal cases where all parties are present from
the very start of the case, and this question warrants Third Circuit review.
B. There is Substantial Ground for Difference of Opinion

Home Depot relies extensively on In re TMI Litig., 193 F.3d 613 (3d Cir. 1999), amended,
199 F.3d 158 (3d Cir. 2000). In TMI, the Third Circuit decided the case based on its interpretation
of Fed. R. Civ. P. 42(a), which allows for consolidation, but different consolidation from that
which is allowed under 28 U.S.C. § 1407. Although, the TMI Court did discuss “issue preclusion”
in the context of collateral estoppel, it ultimately ruled that a summary judgment issued against
one group of plaintiffs could not be applied to a different group of plaintiffs because the different
group never had the opportunity to litigate their claims and never had the “opportunity to object to
the defendants’ motion for summary judgment or otherwise protect their substantive claims.” In
re TMI Litig., 193 F.3d 613, 724 (3d Cir. 1999), amended, 199 F.3d 158 (3d Cir. 2000). Because
that different group of plaintiffs never had the opportunity to be heard on summary judgment,

“issue preclusion” and “law of the case” could not be used to apply summary judgment to them.
Id.
This Court acknowledges that although some language in TMI supports Home Depot’s
position, its procedural history is considerably different from the present action. TMI was not a
class action, and its decision was heavily predicated on the fact that the different group of plaintiffs
never had the opportunity to be heard on the earlier summary judgment. Home Depot did have
this opportunity to be heard as part of a class but chose instead to opt-out as to Lafarge and file its
own action.
Home Depot’s delayed filing triggers this unique procedural situation that the undersigned
believes the Third Circuit should review: whether Home Depot’s decisions to opt-out of the class
settlement as to Lafarge and to delay filing its own lawsuit until 2018 shield it from “issue
preclusion” and “law of the case” applicability. Regardless of the differences between TMI and
the present action, this Court believes the TMI decision demonstrates a difference of opinion

regarding “issue preclusion” and “law of the case” applicability in an MDL.
In its Memorandum Opinion, this Court relied on Phila. Housing Auth. v. Am. Radiator &
Standard Sanitary Corp., 323 F. Supp. 381 (E.D. Pa. 1970). Once again, this decision is not
factually analogous, but it provides a ruling contradictory to that of TMI. The Philadelphia
Housing Court determined it was appropriate to apply one summary judgment decision in the MDL
to another case in the same MDL containing a different a group of plaintiffs. The Court held “an
earlier decision by this Court in this very same multidistrict litigation, Mangano, establishes the
law of this case.” Philadelphia House Auth. v. Am. Radiator & Standard Sanitary Corp., 323 F.
Supp. 381, 385 (E.D. Pa. 1970). This decision supports Home Depot’s argument that substantial
ground for difference of opinion regarding “law of the case” applicability exists.

Home Depot also relied on In re Nissan Motor Corp. Antitrust Litig.. 471 F. Supp. 754
(S.D. Fla. 1979) to support its position. In this case, the Court granted summary judgment against
class action plaintiffs after a jury found no nationwide price-fixing conspiracy existed between the
defendants. Id. at 756. After their success on the class-action summary judgment, defendants then
moved for summary judgment against the non-class plaintiffs in the MDL’s remaining statewide
actions. The Court did not apply the class-action summary judgment to the non-class plaintiffs
because it determined the two cases were essentially separate, so collateral estoppel principles
made application of the Court’s earlier summary judgment ruling to the non-class plaintiffs
improper. Id. at 757–78. Therefore, In re Nissan expresses an opposite result from that of
Philadelphia Housing, again reinforcing the existence of a substantial ground for difference of
opinion on the issue of prior rulings’ applicability to parties joining MDLs later.
C. An Immediate Appeal of this Court’s Order Will Materially Advance
Termination of this Litigation

This Court believes that the Third Circuit undertaking an interlocutory review of this
Court’s Order will, in the language of 1292(b), “materially advance the termination of the
litigation” for three reasons. First, it will directly impact this Court’s ruling on Lafarge’s pending
motion for summary judgment. Second, it will directly impact the trial judge’s management of
this case after transfer. Once this case is returned to the Northern District of Georgia, this Court’s
application of “issue preclusion” and “law of the case” principles may, unless reversed by the
Third Circuit if Home Depot’s appeal is successful, impact the expert opinions and legal issues to
be presented at trial. 5 And third, Third Circuit review of this Court’s Order will also undoubtedly
affect settlement discussions.
Although the undersigned understands granting this Appeal will result in some delay in
pretrial proceedings, it will advance the ultimate termination of this case. The discovery in this
case is entirely concluded. The Court’s Memorandum Opinion details extensive pretrial
proceedings, many of which were held before Home Depot filed its case in the Northern District
of Georgia. This Court has no knowledge of why Home Depot delayed its filing and posits that
perhaps its delay was strategic. Regardless, a Third Circuit decision will expedite this case’s

termination by streamlining this Court’s analysis of Lafarge’s pending summary judgment motion,
by narrowing evidentiary issues and the number of experts who may testify at trial,6 and by

5 This case must be returned to the Northern District of Georgia once pretrial proceedings are
completed in this Court. Lexecon, Inc. v. Milberg Weiss Bershad Hynes & Levach, 523 U.S. 26
(1998).

6 This Court is aware that Home Depot, pursuant to this Court’s Order striking Dr. Kneuper’s
impacting the parties’ settlement discussions.
D. Additional Reasons to Allow this Appeal
1. Home Depot’s Strategy and Arguments Present Serious Procedural
Implications

Home Depot argues this Court’s rulings that were issued before Home Depot transferred
into this MDL should not apply, and accordingly, that this Court had no right to rely on principles
of “issue preclusion” and “law of the case” when ruling on the Dr. Kneuper Daubert motion.
This case is markedly different from others for several reasons. First, Home Depot had
notice and the opportunity to be heard through the class-action, so due process concerns are not at
issue. But then, Home Depot chose to opt out of that class only as to Lafarge, so it remained bound
by this Court’s MDL decisions as to all the remaining defendants. Second, after it opted out and
filed the present action against only Lafarge, Home Depot’s case was transferred to this Court after
it made certain MDL pretrial rulings. Once Home Depot was before this Court again, it presented
expert opinions in direct contravention to earlier rulings.
Home Depot’s strategy presents serious implications. If the Third Circuit affirms this
Court’s Order, judges and parties will know MDL litigants can be bound by rulings issued prior to
their entry into the MDL.
2. Multidistrict Litigation is Vast
The growth of multidistrict ligation is a practical factor warranting Third Circuit appellate

review of this Court’s Order. According to all accounts cited in Home Depot’s Motion, cases

opinion and granting Home Depot leave to submit a new report within sixty (60) days, served a
new report on counsel for Lafarge. (See ECF No. 145.) However, this Court has not reviewed
that new report. Regardless, this Court notes that this event should not obviate the propriety of an
interlocutory appeal because the Court’s Memorandum Opinion, for which Home Depot seeks
certification for interlocutory appeal, severely and substantively limited Dr. Kneuper’s ability to
rely on his own opinions about this case.
within MDLs constitute more than half of all federal civil litigation, so there is a need for additional
guidance from appellate courts on the contours of “issue preclusion” and “law of the case”
applicability not only to various cases within the same MDL, but also specifically in terms of the
applicability of these principles to parties like Home Depot—tag-along parties who first opted out

of a class as to one defendant, but who later joined the MDL, and then presented experts opinions
in contravention to MDL rulings entered before they joined.
3. A Transferee Judge’s Pretrial Rulings Have Immense Impact on the Entire
Life of the MDL

As Judges Rendell and Scirica of this Court undoubtedly know, having served on the JPML
by appointment by the Chief Justice, the rulings a single transferee judge makes during MDL
consolidation can have tremendous impact on hundreds, and sometimes thousands, of separate
cases. This is the responsibility of the transferee judge, yet there does not appear to be any
appellate guidance7 on whether the transferee judge’s earlier MDL holdings are binding on tag-
along plaintiffs, particularly in the expert opinion area, under the doctrines of “issue preclusion”
and/or “law of the case.” This apparent lack of appellate guidance is especially needed in the
procedural context raised by this case: not only is Home Depot a tag-along plaintiff, but Home
Depot previously had the opportunity to be bound by rulings of this Court as part of the class-
action plaintiffs’ MDL, but instead chose to opt-out only as to Lafarge and then filed the present
action; Home Depot essentially skirted earlier MDL rulings, but then joined the MDL later and

7 The impact of the rulings by a MDL transferee judge have been the subject of law review articles
cited by Home Depot, however, there does not appear to be any appellate decisions clearly
addressing the legal propriety a transferee judge’s decision similar to the one made by this Court.
See Joan Steinman’s Law of the Case: A Judicial Puzzle in Consolidated and Transferred Cases
and in Multidistrict Litigation, 135 U. Pa. L. Rev. 595, 697-99 (1987) (generally discussing both
the issues transferee judges considering tag-along cases face and the issues presented by cases that
apply “law of the case principles”, Ms. Steinman suggests stare decisis is preferable to “law of the
case” in these MDL situations).
argued those rulings it had the opportunity to be heard during but chose not to be, should not bind
them or their proposed expert.
4. A Third Circuit Decision Will Maximize Judicial Economy
There is no question that MDL proceedings maximize judicial economy by consolidating

similar cases before a similar judge. The undersigned believes that it would also be very valuable
to attorneys practicing in MDL proceedings, and also to the transferee judges, to have an appellate
ruling on the issues presented by this appeal, particularly because they concern expert testimony.
In complex commercial litigation, which is among the most frequently consolidated type of case
under 28 U.S.C. § 1407, experts play a major role. MDL transferee judges would find it very
valuable to have an appellate court ruling deciding whether prior proceedings and judicial holdings
in an MDL, issued before the receipt of a late “tag-along” case, may be binding on the new arrival.
And, while 28 U.S.C. § 1292(b) clearly sets forth the three-part test for certification for
interlocutory appeal, a Third Circuit decision on the issues presented by this appeal may minimize
the need for interlocutory appellate practice in the future. Although the undersigned recognizes

its ruling is procedurally unique, the fact remains that many transferee courts are faced with the
issue of “law of the case” applicability to various parties. Interlocutory appeal is presently the
only procedural mechanism available to MDL litigants seeking review of transferee courts’ “issue
preclusion” and/or “law of the case” decisions. If transferee judges had Third Circuit guidance on
this issue, fewer interlocutory appeals may be sought by litigants, fewer appeals may be certified
by transferee courts, and thus fewer stays may be implemented. With fewer MDLs stayed pending
interlocutory appeal, the judicial economy MDLs were designed to maximize can be restored.
E. Recent Third Circuit Decisions in MDL Cases Applying “Law of the Case”
Principles

Although not cited by the parties, this Court notes for the benefit of the Third Circuit its
prior decision In re Asbestos Products Liability Litig. (No. VI), 921 F. 3d 98, 106–107 (3d Cir.
2019). This decision analyzed a waiver of personal jurisdiction argument. The Third Circuit
reversed on abuse of discretion grounds a decision by District Judge Robreno issued in a very
complicated asbestos litigation (see In re Asbestos Prod. v. Coffin Turbo Pump, et al., 2:02-md-

00875) in which he was the MDL transferee judge. This Court brings In re Asbestos to the
attention of the Third Circuit, not because it is substantively analogous to the issues presented here,
but because it shows that the Third Circuit, in other situations, weighed in on decisions by an MDL
transferee judge in the midst of ongoing MDL proceedings.
In addition, this Court brings In re Pharm. Benefit Managers Antitrust Litig., 582 F.3d 432,
439–42 (3d Cir. 2009) to the attention of the Third Circuit. In this case, Judge Robreno of this
Court entered an order concerning arbitrability. Subsequently, the case was transferred for pretrial
proceedings under U.S.C. § 1407 to Judge Fullam, a former Judge of this Court, who reversed
Judge Robreno’s Order. On Appeal, without noting whether there was appellate jurisdiction, the
Court ruled that Judge Fullam’s Order must be reversed because Judge Robreno’s decision was

“the law of the case.” In re Pharm. Benefit Managers Antitrust Litig. 582 F 3d.at 436–42.
Although In re. Pharm. Benefit provides another example of appellate intervention, additional
guidance is still needed from the Third Circuit on the specific issues presented by this appeal.
III. CONCLUSION

For the reasons stated above, Home Depot’s Motion for Certification under 28 U.S.C. §
1292(b) is GRANTED. An appropriate Order follows.
