A unanimous California Supreme Court held on July 27, 2026 that a lack of exhaustion does not categorically defeat an insured's controversy with its excess insurers, replacing the blanket prerequisite with a two-part pleading test that reaches an excess carrier's own bad-faith conduct. Seven justices signed, none wrote separately, and the four $10 million layers above Fox Paine's HCC primary now have to answer in a courtroom they expected to sit out.
Chief Justice Patricia Guerrero put her name to a sentence on July 27, 2026 that California's excess insurers had spent years pleading around. The instrument is the California Supreme Court's opinion in Fox Paine & Company, LLC v. Twin City Fire Insurance Company, No. S287404, filed in San Francisco. One passage took the industry's favorite threshold defense and stripped it of its categorical force: "Consistent with these general principles, a lack of exhaustion does not categorically make a coverage dispute involving an excess policy unduly abstract or hypothetical. Imposing a blanket exhaustion prerequisite for the recognition of an actual controversy would place too much emphasis on the fact that a contingency exists, and too little on the likelihood it will occur." Above Fox Paine sat a $50 million structure, $10 million of primary coverage written by HCC and four $10 million excess layers stacked on top of it. Seven justices signed. None wrote separately. Every layer above the primary now has to answer in a courtroom it expected to be able to sit out.
The posture flipped in one line of disposition. "We reverse the judgment of the Court of Appeal and remand the cause to that court for further proceedings consistent with this opinion." The judgment reversed came from the First Appellate District, Division Two, No. A168803. That court had treated the absence of exhaustion below as fatal to an insured's controversy with the insurers above. The fight had been running out of San Francisco City and County Superior Court, No. CGC17557275, and it had turned on sequence rather than on coverage.
What replaced the blanket rule is a pleading test with two moving parts. An insured, the court held, "needs only to allege facts that, taken as true, are sufficient to show that coverage under a defendant insurer's excess policy will attach," or would attach if not for the excess insurer's bad-faith conduct, "and that the insurer's misconduct has impaired the insured's recovery of benefits owed to it under the policy." Attachment becomes a question of likelihood instead of a completed event. The second clause is the one with teeth. An excess insurer's own conduct can no longer be the reason the courthouse door stays shut to the insured complaining about that conduct.
The defendants standing at that door are named on the cover page. Twin City Fire Insurance Company wrote the first excess layer and the third. St. Paul Mercury Insurance Company wrote the second. Liberty Mutual Insurance Company wrote the fourth. Fox Paine's bad-faith allegations against them are still allegations, pleaded and untested. Guerrero's opinion decides only that they get to be tested, which is precisely the thing the exhaustion argument existed to prevent.

Read as strategy, the exhaustion prerequisite was never really an argument about whether coverage existed. It was an argument about when anyone would find out. A tower pays from the bottom up, so an excess carrier that treats attachment as a condition precedent to being sued converts layer order into a waiting period, and waiting is the cheapest coverage defense there is. The court declined to call that waiting period an abstraction. A contingency that is likely to occur is not the same thing as a hypothetical, and the opinion puts the emphasis on the likelihood. The carrier structural defense, last seen in these pages in JW Aluminum's Fourth Circuit fight with ACE, where a $10 million endorsement sub-limit gave way to a restored $80 million sub-limit and a $112.3 million verdict that William T. Reid IV called "pretty dramatic" to The Texas Lawbook, now meets a California rule that kills the play a step earlier, at the pleading.
None of which means Fox Paine collects. The $50 million is the shape of the tower, not a number any insurer has been ordered to pay, and nothing in the opinion says excess benefits are payable now or that bad faith happened at all. What the opinion removes is a gate. Gibson Dunn, reading the decision for the defense bar in its client alert, described the holding the same way: failure to exhaust underlying policies does not categorically preclude an insured's claims against an excess insurer.
The next move belongs to Division Two. The cause returns there for proceedings consistent with an opinion that removed the ground its judgment stood on, and no hearing date is on the public record yet. The options left to the excess layers have narrowed to three. Litigate attachment on the facts, litigate whether their own conduct impaired recovery, or price a settlement of a tower they can no longer defend on sequence alone. Each of those roads runs through discovery into claim handling, which is the exact record an exhaustion dismissal used to keep sealed.
Guerrero wrote for a unanimous court and did not need a single separate opinion to do it, and that is the part the market will read first. A 7-0 California Supreme Court has told every insured under every stacked program in the state that the layers above are reachable while the layers below are still in dispute. The gate is gone. The tower is open. What is inside it is still a fight.
