In re IKO Roofing Shingle Products Liability Litigation
Purchasers of organic asphalt roofing shingles in many states have filed suits against IKO Manufacturing and affiliated firms, contending that it falsely told customers that these shingles met an industry standard known as ASTM D225, and that
In 2009 the Panel on Multidistrict Litigation transferred all of the federal suits to the Central District of Illinois for consolidated pretrial proceedings under
Before addressing plaintiffs’ arguments about the class-certification decision, we must consider whether the judge who denied plaintiffs’ motion had authority to preside over the litigation.
If the problem deprived the court of subject-matter jurisdiction, then there is nothing for us to do but vacate the order of January 28 — and every other order Judge Baker entered during the preceding four years. We do not think, however, that
All of these suits are properly in federal court, and for that matter properly in the Central District of Illinois for consolidated pretrial proceedings. A district court’s error in complying with

The transfer of these proceedings to Judge Baker is on the technical side of Nguyen’s line. No one thinks him ineligible to be a transferee judge. The Panel now has designated him to serve in that capacity. Given the technical nature of this problem and the lack of objection by any litigant, we need not decide whether the Panel’s order would have had retroactive effect and thus overridden a litigant’s objection to Judge Baker’s role.
On to the class-certification issue. One vital question under
The court read Comcast Corp. v. Behrend, — U.S. —,
Yet Wal-Mart has nothing to do with commonality of damages. It dealt instead with the need for conduct common to members of the class, and it concerned
Comcast, by contrast, does discuss the role of injury under
That would be equally true in a suit with just one plaintiff. In antitrust law, damages are limited to the sort of injury that flows from unlawful conduct. See, e.g., Brunswick Corp. v. Pueblo Bowl-O-Mat, Inc.,
The second theory is that purchasers whose tiles actually failed are entitled to recover damages, if nonconformity to the D225 standard caused the failure. That sort of remedy would require buyer-specific hearings along the lines discussed in Butler,
A buyer-specific remedial approach would require confining any class certification to questions of liability, as in Pella I and Butler. It is not hard to frame liability issues suited to class-wide resolution. (1) Did IKO’s tiles generally conform to the substantive aspects of the D225 specification? (“Generally” is an important qualifier. In any mass production operation, defects or deviations are inevitable.) (2) Did IKO test the tiles according to the D228 procedure? (3) If IKO failed to use the D228 procedure, did it nonetheless test its output in a way that would verify compliance? (If yes, this implies that a negative answer to Question 2 would not play a causal role in buyers’ losses.) (4) Did any failure to satisfy the D225 standard cause the sorts of problems plaintiffs reported, or would roughly the same failure rate have been experienced with complying tiles? (The answer could be “no causation” because the difference between D225-compliant tiles and other organic tiles is sufficiently small that it would not lead to a materially different failure rate.)
We do not say that a district court is required to certify a class action on all four of these subjects, or on a class-wide damages theory, or indeed on any issue. A district judge has discretion to evaluate practical considerations that may make class treatment unwieldy despite the apparently common issues. On occasion the problems are so grave that it is an abuse of discretion to certify a class. See, e.g., Parko v. Shell Oil Co.,
The papers filed in this court address a number of additional issues that are outside the scope of a
Getting these numbers right will be a central task for the district court whether or not a class is certified on remand. Development of facts also may influence the ultimate decision about class certification — and, to repeat, we do not say that certification is required (or necessarily would be prudent), or what if any issues should be certified. Those matters are for the district court.
The decision declining to certify a class is vacated, and the case is remanded for proceedings consistent with this opinion.
