American Airlines, Inc. v. Robert Mawhinney, 904 F.3d 1114

Background

Mawhinney, a former American Airlines mechanic, settled a 2002 AIR21 whistleblower retaliation claim with American; DOL approved the settlement, which included a broad arbitration clause and California choice-of-law.
After renewed alleged whistleblowing in 2010–11, American disciplined and then fired Mawhinney; he filed (1) an arbitration for related state-law claims and (2) an AIR21 complaint with DOL naming both American and TWU Local 591.
DOL investigated and found no reasonable cause; Mawhinney requested an ALJ hearing. ALJ dismissed the Union from the AIR21 claim; the ARB reversed as to the Union and remanded on contractor/company questions.
American moved to compel arbitration of the AIR21 dispute after the bankruptcy stay lifted; ARB reversed an ALJ order compelling arbitration but said American could seek arbitration in court. American sued in district court to enforce the settlement/DOL order and moved to compel arbitration; the Union brought a similar enforcement action and moved to compel.
The district court granted both motions to compel arbitration and dismissed; Mawhinney appealed. This Court affirmed American’s right to compel arbitration but reversed the Union’s ability to do so.

Issues

Issue	Mawhinney's Argument	American/Union's Argument	Held
Whether American waived its arbitration right by participating in DOL investigation	Waiver because American participated in DOL process and delayed motion to compel	No waiver: DOL investigation was an independent, non‑adversarial agency proceeding; American timely asserted arbitration once able	No waiver — arbitration enforceable against American
Whether AIR21 or the administrative scheme forbids private arbitration of an AIR21 claim	AIR21/DOL process requires agency adjudication; private arbitration is incompatible	AIR21 does not expressly bar arbitration; once DOL investigation ends, remaining dispute is private and subject to parties’ arbitration agreement	AIR21 does not bar arbitration of the private AIR21 claim
Whether American’s contract action to compel arbitration was time‑barred under California statute of limitations	Time-barred because suit filed more than four years after Mawhinney’s DOL filing	Limitations began when Mawhinney refused to arbitrate (2014); suit within four years	Not time‑barred; limitations began on refusal to arbitrate
Whether TWU Local 591 can enforce the settlement/DOL order and compel arbitration	Union: can enforce because it functions as American’s agent or otherwise is covered/beneficiary	Mawhinney: Union is not a party or beneficiary; cannot enforce arbitration	Union cannot enforce the arbitration clause — not American’s agent nor a party/beneficiary; district court’s order as to Union reversed
