Abella Owners' Association v. MI Windows & Doors, Inc., 860 F.3d 218

MDL consolidated 18 class actions against MI Windows in District of South Carolina over allegedly defective windows; parties negotiated a settlement providing repairs, damages, and broad releases.
District court preliminarily approved the settlement, certified a settlement class under Rule 23, approved notice procedures, and set an opt-out deadline of May 28, 2015; final fairness hearing and final judgment occurred July 22, 2015.
Final judgment approved the settlement, permanently enjoined class members from pursuing related claims against MI Windows, and dismissed the MDL cases; the settlement released known and unknown claims “related to” MI Windows’ product.
Abella Owners’ Association was a class member that received notice but did not timely opt out; Abella continued prosecuting a related California state-court suit against MI Windows.
MI Windows moved in the MDL court to enjoin Abella from continuing the California action; the district court granted the injunction (Jan. 15, 2016), finding the Anti‑Injunction Act’s relitigation exception applied and that Abella’s counsel’s failure to opt out was not excusable neglect.
Abella appealed, challenging the Anti‑Injunction Act ruling and the denial of relief for excusable neglect; the Fourth Circuit affirmed.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Anti‑Injunction Act bars injunction against Abella’s state suit	Act bars federal injunction of state proceedings; MDL court may not enjoin Abella	Injunction falls within relitigation exception to protect/effectuate the MDL judgment	Injunction allowed under relitigation exception; judgment is claim‑preclusive
Whether final class settlement judgment precludes Abella’s California claims (res judicata)	Abella not a named party; cannot be bound as to those claims	Abella was a class member with notice, adequately represented, who failed to opt out; judgment on the merits releases identical factual claims	Judgment operates as claim preclusive; Abella’s claims arise from same factual predicate and are released
Whether court abused discretion in denying relief for excusable neglect	Counsel’s inadvertence and scheduling justify relief under Pioneer factors	Delay was long, within counsel’s control, and prejudicial to finality; relief unwarranted	Denial of relief was within district court’s discretion under Pioneer factors
Whether equitable estoppel prevents enforcement	MI Windows failed to separately notify Abella; estoppel should bar enforcement	Court-approved notice was sufficient; any omission by MI counsel not dispositive	Abella abandoned estoppel on appeal; district court correctly rejected estoppel at trial-court stage
