CACD Federal MTD — Forum Non Conveniens and Abstention

Forum non conveniens (FNC) is a discretionary doctrine permitting dismissal in favor of a more appropriate forum. Sinochem International Co. v. Malaysia International Shipping Corp., 549 U.S. 422 (2007). Where parties have a valid forum-selection clause, Atlantic Marine creates a strong default in favor of enforcement; where the clause is permissive or absent, the traditional Piper Aircraft balancing applies.

Atlantic Marine framework for valid mandatory FSCs

When parties have a valid mandatory forum-selection clause, the analysis shifts dramatically: "the plaintiff's choice of forum merits no weight," and "a district court should ordinarily transfer the case to the forum specified in that clause." Atlantic Marine Construction Co. v. U.S. District Court, 571 U.S. 49, 62–63 (2013). Only "extraordinary circumstances unrelated to the convenience of the parties" justify denying enforcement.

Mandatory vs. permissive clauses

Whether a clause is mandatory (exclusive) or permissive (non-exclusive) is the threshold question. A clause designating one forum exclusively triggers Atlantic Marine; a clause allowing suit in multiple fora reverts to traditional FNC analysis. Lavera Skin Care N. Am. v. Laverana GMBH (9th Cir. 2017, unpub.). Carve-outs (e.g., a single category of claims directed to a different forum) commonly render the clause permissive overall.

State law governs threshold validity

The enforceability of the FSC itself is a state-law question. DePuy Synthes Sales, DePuy Synthes Sales, Inc. v. Howmedica Osteonics Corp., 28 F.4th 956 (9th Cir. 2022). Federal Atlantic Marine deference applies only to a valid clause; if state law voids the clause, the federal default never engages.

Traditional FNC: Piper two-part test

Where Atlantic Marine does not apply, FNC analysis proceeds in two steps:

1. Adequate alternative forum. Defendant must be amenable to service in the alternative forum, and the forum must offer a meaningful remedy. Piper Aircraft Co. v. Reyno, 454 U.S. 235 (1981); Lueck v. Sundstrand Corp., 236 F.3d 1137 (9th Cir. 2001). Less-favorable substantive law abroad is generally not weighed against adequacy. Ravelo Monegro v. Rosa, 211 F.3d 509 (9th Cir. 2000). English courts and other Common-law fora are routinely treated as adequate. Richards v. Lloyd's of London, 135 F.3d 1289 (9th Cir. 1998); British Midland Airways Ltd. v. International Travel, British Midland Airways Ltd. v. International Travel, Inc., 497 F.2d 869 (9th Cir. 1974).

2. Private and public interest factors. Carijano v. Occidental Petroleum Corp., 643 F.3d 1216 (9th Cir. 2011); Dole Food Co. v. Watts, 303 F.3d 1104 (9th Cir. 2002). Private factors include access to evidence and witnesses; public factors include local interest, court congestion, and the need to apply foreign law. Where foreign law governs, that factor weighs heavily for dismissal. Loya v. Starwood Hotels & Resorts, 583 F.3d 656 (9th Cir. 2009). A pending parallel suit by defendant in the alternative forum is affirmative evidence of forum adequacy and amenability to service.

How CACD applies it (corpus examples)

• 445915790 (Manilow v. Hipgnosis SFH I Limited — Sykes): granted FNC dismissal; Music Catalogue Acquisition Agreement designated England with a permissive carve-out for California/New York Purchase Price claims; treated as permissive overall, traditional Piper analysis; England adequate (Hipgnosis amenable, parallel English action pending); English law governed contract; private and public interest factors favored England (witnesses and evidence in England, federal-court congestion); international comity not reached.

If you're the moving party

• Identify whether the FSC is mandatory or permissive. A pure exclusive clause unlocks Atlantic Marine's near-default deference.
• For permissive clauses, build the Piper case: amenability to service, parallel proceeding (if any), governing-law analysis, witness location, evidence location.
• Where foreign law governs, lead with Loya — the need to apply foreign law is a heavy public-interest factor.
• Cite federal-caseload statistics (uscourts.gov annual reports) for the court-congestion public-interest factor.

If you're the opposing party

• Attack threshold validity under state law (DePuy Synthes route). California Labor Code § 925 voids many out-of-state FSCs in employment contracts.
• Frame the clause as permissive if any carve-out exists. Permissive treatment defeats Atlantic Marine and forces the movant to carry traditional Piper factors.
• Plead specific facts on inadequacy of the alternative forum: limitations bars, immunities, remedy gaps. Generic less-favorable-law arguments fail under Ravelo Monegro.
• For multi-claim cases, identify claims outside the scope of the FSC — employment torts, statutory wage claims, and similar typically fall outside merger-document FSCs.

Under the Declaratory Judgment Act, district courts have discretion whether to entertain declaratory-judgment actions. 28 U.S.C. § 2201(a). The Supreme Court has long recognized "substantial latitude in deciding whether to stay or to dismiss" where state proceedings are pending. Wilton v. Seven Falls Co., 515 U.S. 277, 288 (1995). Brillhart abstention is the central CACD vehicle for declining federal jurisdiction over coverage disputes and other declaratory actions paralleling state litigation.

Article III ripeness for insurance-coverage disputes

Insurance-coverage disputes between insurer and insureds satisfy Article III's case-or-controversy requirement under the long-settled rule of Maryland Casualty Co. v. Pacific Coal & Oil Co., 312 U.S. 270 (1941). Government Employees Insurance Co. v. Dizol, 133 F.3d 1220, 1223 n.2 (9th Cir. 1998).

The Dizol three-factor test

Once Article III is satisfied, the court's exercise of declaratory jurisdiction is discretionary. The Ninth Circuit applies three Brillhart factors. Government Employees Insurance Co. v. Dizol, 133 F.3d 1220, 1225 (9th Cir. 1998):

1. Avoid needless determination of state-law issues. Where the dispute is pure state law and every party is also in state court, this factor weighs against jurisdiction. Argonaut Insurance Co. v. St. Francis Medical Center, 17 F.4th 1276, 1284–85 (9th Cir. 2021) (no requirement of identical issues; substantially overlapping facts suffice).

2. Discourage forum shopping (especially "reactive declaratory actions"). "Insurer may anticipate that its insured intends to file a non-removable state court action, and rush to file a federal action before the insured does so." Continental Casualty Co. v. Robsac Industries, 947 F.2d 1367, 1372 (9th Cir. 1991). Where the federal complaint is filed shortly after the insurer learns the insured will file or amend a state-court action, the reactive-filing inference applies. Without that race-to-the-courthouse evidence, the factor is neutral. Huth v. Hartford Insurance Co. of the Midwest, 298 F.3d 800, 804 (9th Cir. 2002).

3. Avoid duplicative litigation. Brillhart v. Excess Insurance Co. of America, 316 U.S. 491, 495 (1942) ("uneconomical as well as vexatious"). Where state and federal actions present substantially the same issue, this factor weighs against jurisdiction.

Procedural posture: Rule 12(b)(1)

Brillhart "does not fit neatly into any of the categories of motions enumerated in Rule 12(b)." Inari Medical, Inc. v. McCaskey, 733 F. Supp. 3d 998, 1002 (D. Or. 2024). Most district courts in the Ninth Circuit treat it as a Rule 12(b)(1) subject-matter-jurisdiction question — which permits consideration of extrinsic evidence outside the complaint. Warren v. Fox Family Worldwide, 171 F. Supp. 2d 1057, 1060–62 (C.D. Cal. 2001).

Sua sponte redirection

A distinctive CACD pattern: where the parties brief Colorado River abstention but the doctrinal vehicle is actually Brillhart, the court may pivot to the right framework on its own and call for supplemental briefing. The court will pick the right framework even if the parties miss it.

How CACD applies it (corpus examples)

• 465178645 (State National Insurance v. Mostafavi — Garnett): granted Brillhart abstention; insurer filed federal declaratory action approximately one week after insured emailed about amending the state complaint to add a coverage-declaratory claim; court redirected from parties' Colorado River framework to Brillhart sua sponte after supplemental briefing; all three Dizol factors weighed against jurisdiction; dismissed without prejudice.

If you're the moving party (state-court party seeking abstention)

• Build the reactive-filing record. Email correspondence showing the federal plaintiff knew a state action was imminent or being amended is the load-bearing evidence.
• Map the state and federal actions issue-by-issue — substantial factual overlap is enough; identical claims are not required (Argonaut).
• For pure state-law coverage disputes with all parties already in state court, lead with the first Dizol factor.
• If the parties have briefed Colorado River, raise Brillhart in the alternative — the court can and will pivot.

If you're the opposing party (federal plaintiff seeking jurisdiction)

• Distinguish the timing — file before the state action is amended, and document any independent reasons for federal filing.
• Argue Huth neutrality where there is no contemporaneous evidence of awareness of the imminent state action.
• Identify federal-law components of the dispute (e.g., bankruptcy, securities, federal-agency interpretation) to weaken the first Dizol factor.
• For non-coverage declaratory actions outside Brillhart's traditional core, argue Colorado River's narrower framework instead.
