Mendez v. Trustmark National Bank, 986 F.3d 931

This litigation arises from the R. Allen Stanford Ponzi scheme; the SEC appointed Ralph Janvey as federal receiver and a court-created Official Stanford Investors Committee (OSIC) to represent investor interests.
Plaintiffs sued banks that provided services to Stanford alleging fraud, fraudulent transfer, conversion, civil conspiracy, and statutory claims; OSIC intervened asserting claims on behalf of the receiver, the receivership estate, and Stanford investors.
The district court denied class certification in November 2017; after class denial, the parties proceeded to extensive fact discovery.
In April 2019, following communications from OSIC and the Examiner that Appellants viewed as ambiguous about investor representation, investor-appellants moved to intervene as of right (and alternatively permissively), asserting duplicative investor claims.
The district court denied intervention as untimely and because OSIC adequately represented the appellants; the Fifth Circuit affirmed denial of intervention as of right and dismissed the appeal of permissive intervention.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Timeliness of intervention as of right	Appellants: motion timely because April 2019 statements created uncertainty about OSIC representation	Opposing parties: timeliness measured from denial of class certification; appellants waited ~18 months	Motion untimely; 18‑month delay weighed heavily against intervention; district court did not abuse discretion
Adequacy of representation / Standing of OSIC	Appellants: OSIC (and receiver) may lack standing to pursue investor claims (citing Lloyds) so representation could be inadequate	OSIC/receivership: investors' claims are derivative/dependent on receivership; OSIC (as assignee) owes fiduciary duties and will distribute recovery	Court held OSIC has standing to assert investors’ claims as derivative of receiver’s claims (following Zacarias); adequacy concern diminished
Permissive intervention	Appellants: alternatively seek permissive intervention to litigate individual claims	Opposing parties: untimely; would cause discovery duplication and delay	District court did not abuse discretion in denying permissive intervention; appeal dismissed for lack of jurisdiction
Motion to strike / Personal jurisdiction argument	Defendants S.G. Suisse and Friedli raised personal jurisdiction as an alternative basis to affirm denial	OSIC moved to strike PJ argument for failure to cross-appeal	Motion to strike denied; PJ argument not accepted as basis to overturn denial of intervention
