Till Derr v. Thomas Swarek, 766 F.3d 430

Background

In 2005 the Swareks and Derr/Derr Plantation, Inc. executed a Lease/Buy/Sell agreement for Mississippi farmland; the Swareks sued in Mississippi chancery court for breach and specific performance.
Derr died in 2006; the Swareks moved to substitute his estate but later voluntarily dismissed all claims against Derr with prejudice in May 2010 and withdrew substitution motions.
While Mississippi litigation was stayed, Derr’s heirs (the Derr Heirs) sued the Swareks in Germany seeking a declaratory judgment of non-liability; the German trial court dismissed but the Higher Regional Court reversed and awarded costs to the Heirs (~$300,000).
The Derr Heirs sought to enforce the German costs award in a U.S. federal district court; the district court refused comity and entered judgment for the Swareks.
On appeal, the Fifth Circuit affirmed: it held (1) filing a parallel foreign proceeding alone does not defeat comity, but (2) the Swareks’ voluntary dismissal with prejudice in Mississippi operated as a final judgment on the merits and, via privity, barred re‑litigation by the Derr Heirs (res judicata), so the German court’s award was based on ignoring that bar and was not entitled to comity.

Issues

Issue	Plaintiff's Argument (Swareks)	Defendant's Argument (Derr Heirs)	Held
Whether a foreign parallel proceeding alone justifies refusing comity to its judgment	German suit interfered with Mississippi litigation and thus should not be recognized	Parallel foreign suits are permissible; initiating one does not alone defeat comity	Filing a mirror foreign suit while domestic litigation is pending is not, by itself, a ground to deny comity
Whether the Swareks’ voluntary dismissal with prejudice in Mississippi had claim‑preclusive effect against Derr and his privies	Dismissal with prejudice under Rule 41(a)(1) was a final judgment on the merits that bars re‑litigation, including against privies	Mississippi courts lacked jurisdiction over Derr (improper service), so dismissal cannot have preclusive effect	Voluntary dismissal with prejudice is a legally operative final judgment under Mississippi law and, through privity, bars subsequent suits against Derr’s successors-in-interest
Whether the German Higher Regional Court should have recognized the Mississippi dismissal (i.e., whether enforcement of the German costs award violates Mississippi public policy)	German court ignored the res judicata effect, issued a superfluous declaratory judgment and costs; enforcing costs would undermine Mississippi public policy favoring finality	German court applied its own law and procedure; costs award is independent and enforceable	Because the German court ignored the Mississippi res judicata bar and issued a redundant declaration (and attendant costs) that defeated Mississippi public policy, comity was properly withheld
Whether the district court abused discretion in refusing to enforce the German costs judgment	Refusal to extend comity was proper given the conflict with the preclusive effect of the Mississippi dismissal	Enforcement should be granted because foreign procedural choices and alternate legal bases do not automatically defeat comity	No abuse of discretion: district court correctly refused comity where recognition would undercut res judicata/finality in Mississippi
