Every case should be read in context: what policy language applied, which statute was then in effect, what procedural posture produced the ruling, and exactly what the court held.

Current authority and review-status watch

Fox Paine & Co., LLC v. Twin City Fire Insurance Co.

S287404 · filed July 27, 2026

Current California Supreme Court authority concerning excess insurance. Completed exhaustion of every underlying layer is not, by itself, required at the pleading stage for declaratory relief or tortious breach of the implied covenant. The insured still must adequately allege covered loss sufficient to implicate the excess layer and, for bad faith, misconduct that impaired recovery of policy benefits.

Gilliland v. City of Pleasanton

116 Cal.App.5th 138 · Supreme Court No. S294539

Addresses Vehicle Code §17004.7 police-pursuit immunity and the meaning of a perceived pursuit. Supreme Court review was granted March 18, 2026; merits briefing was completed August 3, 2026, and amicus briefs were filed in September. The Court of Appeal opinion is not ordinary binding precedent while review is pending. Under the Supreme Court’s grant order, however, it may be cited for persuasive value and for the limited conflict-of-authority purpose specified in Rule 8.1115(e)(3).

John’s Grill, Inc. v. Hartford Financial Services Group, Inc.

S278481 · filed August 8, 2024

Supreme Court insurance-policy interpretation authority enforcing a clear specified-cause limitation in a virus-coverage endorsement. The Court rejected use of the illusory-coverage doctrine to eliminate an unambiguous limitation merely because the insured had little realistic prospect of satisfying it.

Infinity Select Insurance Co. v. Superior Court

F085014 · modified Aug. 30, 2023 · partial publication

Rejects reformation of a commercial automobile policy from its stated $50,000 bodily-injury limit to $750,000 under the Motor Carriers of Property Permit Act where the statutory, regulatory and contractual predicates for that expanded coverage were absent. Only the published portions of the modified opinion carry precedential force.

California appellate dockets

published/citable opinions

Rule 8.1115

Automobile liability, permissive use & mandatory coverage

Wildman v. Government Employees’ Insurance Co.

48 Cal.2d 31

Foundational automobile financial-responsibility authority protecting members of the public injured through operation of an insured vehicle by a permissive user.

Barrera v. State Farm Mutual Automobile Insurance Co.

71 Cal.2d 659

Important California automobile public-policy authority concerning an insurer’s responsibility to investigate insurability within a reasonable period rather than waiting until after an accident to challenge the policy.

Metz v. Universal Underwriters Insurance Co.

10 Cal.3d 45

Leading permissive-use case applying the statutory policy protecting persons injured by permissive users and rejecting policy language functioning as an impermissible exclusion of a class of permissive users.

Farmers Insurance Exchange v. Cocking

29 Cal.3d 383

Upholds a statutorily authorized automobile liability exclusion for bodily injury to an insured household member and illustrates the importance of distinguishing a legislatively permitted exclusion from an impermissible attempt to evade mandatory coverage.

Vargas v. Athena Assurance Co.

95 Cal.App.4th 461

Explains that Insurance Code §11580.1’s mandatory permissive-user protection concerns covered vehicles owned or leased by the named insured and does not require identical permissive-use coverage for every nonowned vehicle.

Allied Premier Insurance v. United Financial Casualty Co.

15 Cal.5th 20 (2023)

Under the Motor Carriers of Property Permit Act, a commercial auto policy does not remain in force merely because the corresponding DMV certificate of insurance has not been cancelled. Policy duration is governed by the contract and any operative endorsement; the Act does not itself extend an expired policy.

Insurance policy interpretation, exclusions & limitations

Waller v. Truck Insurance Exchange, Inc.

11 Cal.4th 1

Central California policy-interpretation case: begin with the contractual language, interpret it in context and according to its ordinary meaning, and require coverage before bad-faith liability based on withholding policy benefits.

AIU Insurance Co. v. Superior Court

51 Cal.3d 807

Foundational interpretation authority requiring policy language to be understood in its ordinary and popular sense unless the parties use terms in a technical or special sense.

MacKinnon v. Truck Insurance Exchange

31 Cal.4th 635

Important exclusion-construction authority. Exclusions are read narrowly and must be interpreted in the context of the policy and the objectively reasonable expectations created by its language.

Haynes v. Farmers Insurance Exchange

32 Cal.4th 1198

Leading automobile-insurance conspicuousness authority. A limitation on otherwise expected coverage must be positioned and presented so that it is sufficiently conspicuous, plain and clear.

Minkler v. Safeco Insurance Co. of America

49 Cal.4th 315

Reinforces California’s rules for ambiguity and the need to read exclusions from the standpoint of a reasonable insured in the context of the entire policy.

Palmer v. Truck Insurance Exchange

21 Cal.4th 1109

Applies California’s established framework for interpreting exclusions and confirms that clear policy language is enforced while genuine ambiguities are construed according to California insurance doctrine.

State Farm Mutual Automobile Insurance Co. v. Jacober

10 Cal.3d 193

Important automobile-policy construction authority addressing exclusionary language in light of statutory and public-policy requirements.

Safeco Insurance Co. v. Robert S.

26 Cal.4th 758

Illustrates California’s refusal to stretch exclusion language beyond what its text reasonably communicates to the insured.

Duty to defend, reservation of rights & independent counsel

Gray v. Zurich Insurance Co.

65 Cal.2d 263

Foundational duty-to-defend authority. The defense obligation is broader than the ultimate duty to indemnify and exclusions must be clearly expressed.

Montrose Chemical Corp. v. Superior Court

6 Cal.4th 287

Establishes the familiar potential-for-coverage framework: the defense duty arises when facts known to the insurer create a possibility that the claim may fall within coverage.

Horace Mann Insurance Co. v. Barbara B.

4 Cal.4th 1076

Reinforces the breadth of the defense obligation and the requirement to defend an entire action when covered and potentially uncovered theories are intertwined under the governing circumstances.

Buss v. Superior Court

16 Cal.4th 35

Explains the insurer’s duty to defend a mixed action and addresses reimbursement of defense expense attributable solely to claims that were never even potentially covered.

San Diego Navy Federal Credit Union v. Cumis Insurance Society

162 Cal.App.3d 358

Historic independent-counsel authority where insurer-appointed counsel faces a material conflict between insured and insurer; subsequently addressed by Civil Code §2860.

Blue Ridge Insurance Co. v. Jacobsen

25 Cal.4th 489

Addresses an insurer’s settlement of a defended case over its insured’s objection and the requirements for preserving reimbursement rights after an appropriate reservation.

Uninsured / underinsured motorist coverage & stacking

Wagner v. State Farm Mutual Automobile Insurance Co.

40 Cal.3d 460

Leading California anti-stacking authority enforcing the statutory and contractual limitation on aggregating multiple UM coverages in the circumstances presented.

Hartford Fire Insurance Co. v. Macri

4 Cal.4th 318

Distinguishes UM from UIM settlement rules. The statutory UM consent-to-settle requirement does not govern UIM claims, which are controlled by Insurance Code §11580.2(p).

Quintano v. Mercury Casualty Co.

11 Cal.4th 1049

Reinforces the statutory distinction between uninsured and underinsured motorist procedures and refuses to import a UM procedural condition into the separate UIM statutory scheme.

Bouton v. USAA Casualty Insurance Co.

43 Cal.4th 1190

Important §11580.2 authority emphasizing the statutory nature of California UM coverage and the relationship between required coverage and the persons insured under the liability portion of the policy.

GEICO v. Oliver

192 Cal.App.3d 12

Applies California’s statutory anti-stacking provisions to multiple automobile policies and demonstrates that the coverage search and the stacking limitation are separate analytical steps.

Allstate Insurance Co. v. Mercury Insurance Co.

154 Cal.App.4th 1253

Addresses allocation and priority among overlapping automobile insurance coverages and illustrates the need to identify all applicable policies before applying priority limitations.

Claims handling, good faith, settlement & excess exposure

Comunale v. Traders & General Insurance Co.

50 Cal.2d 654

Foundational third-party bad-faith settlement authority. An insurer can become responsible beyond policy limits where it wrongfully refuses a reasonable within-limits settlement and exposes its insured to an excess judgment.

Crisci v. Security Insurance Co.

66 Cal.2d 425

The insurer must give at least as much consideration to the insured’s financial interests as to its own when evaluating an opportunity to protect the insured from excess liability.

Johansen v. California State Automobile Assn.

15 Cal.3d 9

An insurer cannot refuse a reasonable settlement opportunity merely because it disputes coverage and thereby shift the excess-judgment risk to its insured.

Gruenberg v. Aetna Insurance Co.

9 Cal.3d 566

Establishes the insurer’s implied covenant obligation not to withhold policy benefits unreasonably or without proper cause.

Egan v. Mutual of Omaha Insurance Co.

24 Cal.3d 809

Insurers must thoroughly and fairly investigate claims and cannot deny benefits without adequately considering evidence supporting coverage.

Neal v. Farmers Insurance Exchange

21 Cal.3d 910

Automobile UM bad-faith authority recognizing liability where an insurer’s handling of a covered first-party claim was unreasonable and sufficiently oppressive to support the remedies established by California insurance law.

Moradi-Shalal v. Fireman’s Fund Insurance Companies

46 Cal.3d 287

Holds that Insurance Code §790.03 does not itself create the former private statutory damages action for unfair claims practices; contractual and common-law remedies remain separate.

Wilson v. 21st Century Insurance Co.

42 Cal.4th 713

Reaffirms that an insurer must fairly investigate and evaluate a first-party claim and may not selectively rely on evidence favoring denial.

Pinto v. Farmers Insurance Exchange

61 Cal.App.5th 676

Failure to accept a settlement demand is not bad faith per se. Third-party bad-faith liability requires unreasonable insurer conduct, not merely proof that settlement did not occur.

Insurance agents, brokers & failure to procure coverage

Jones v. Grewe

189 Cal.App.3d 950

Establishes the ordinary California producer duty: reasonable care, diligence and judgment in procuring the insurance requested, without a general duty to guarantee complete protection.

Fitzpatrick v. Hayes

57 Cal.App.4th 916

Defines the recognized circumstances that can create an expanded producer duty: misrepresentation, a specific request or inquiry, or an assumed duty based on agreement or specialized expertise.

Paper Savers, Inc. v. Nacsa

51 Cal.App.4th 1090

An affirmative misrepresentation concerning the nature or scope of insurance can create producer liability beyond the ordinary limited duty.

Hydro-Mill Co. v. Hayward, Tilton & Rolapp Insurance Associates

115 Cal.App.4th 1145

Addresses failure to procure requested coverage, causation and the two-year professional-negligence limitations period applicable to the insurance-producer claim there.

Butcher v. Truck Insurance Exchange

77 Cal.App.4th 1442

Applies procurement principles where insureds alleged an instruction to duplicate existing protection and addresses causation and accrual.

Pacific Rim Mechanical Contractors, Inc. v. Aon Risk Insurance Services West, Inc.

203 Cal.App.4th 1278

Reinforces California’s limited producer-duty framework and rejects judicial expansion of a broker’s obligations beyond duties actually undertaken or recognized by law.

Comparative fault, medical damages & noneconomic allocation

Li v. Yellow Cab Co.

13 Cal.3d 804

Replaced contributory negligence with California’s pure comparative fault system, allocating liability in direct proportion to fault even where the plaintiff is equally or more responsible than the defendant.

American Motorcycle Assn. v. Superior Court

20 Cal.3d 578

Extended comparative-fault principles among concurrent tortfeasors through comparative equitable indemnity.

DaFonte v. Up-Right, Inc.

2 Cal.4th 593

Proposition 51 compares a defendant’s responsibility with all proven fault responsible for the injury, including fault attributable to persons not remaining as defendants at trial.

Howell v. Hamilton Meats & Provisions, Inc.

52 Cal.4th 541

An insured plaintiff cannot recover contractual medical write-offs that neither the plaintiff nor insurer paid or remained obligated to pay.

Corenbaum v. Lampkin

215 Cal.App.4th 1308

Applies Howell to evidentiary use of gross medical charges extinguished through negotiated payment and rejects using those inflated amounts as an automatic measure of future medical or noneconomic damages.

Pebley v. Santa Clara Organics, LLC

22 Cal.App.5th 1266

Addresses an insured plaintiff who elected out-of-network treatment and actually incurred the charges, allowing proof directed to the reasonable value of that care.

Yaffee v. Skeen

106 Cal.App.5th 1281 (2024) · review denied Mar. 26, 2025

Reinforces that past medical damages are capped by the amount actually incurred while reasonable value must still be proved. It also requires substantial evidence showing future medical care is reasonably certain, not merely a possible treatment contingent on a future trial procedure.

Audish v. Macias

102 Cal.App.5th 740 (2024) · review denied Aug. 21, 2024

Holds that properly founded evidence concerning future Medicare eligibility and expected payment rates can be relevant to the reasonable value of future medical care without necessarily violating the collateral-source rule.

B.B. v. County of Los Angeles

10 Cal.5th 1

Proposition 51 does not allow an intentional tortfeasor to reduce noneconomic liability merely because negligent actors also contributed to the harm.

Government vehicles, claims presentation & immunity

Brummett v. County of Sacramento

21 Cal.3d 880

Vehicle Code §17004 employee emergency-vehicle immunity does not by itself eliminate the public entity’s separate statutory liability under Vehicle Code §17001.

Ramirez v. City of Gardena

5 Cal.5th 995

Interprets Vehicle Code §17004.7’s police-pursuit immunity framework, including statutory pursuit-policy and training requirements.

DiCampli-Mintz v. County of Santa Clara

55 Cal.4th 983

Strictly applies Government Code §915 claim-presentation requirements. Delivery to a government department handling claims does not automatically satisfy the statutory recipient requirement.

Stockett v. Association of California Water Agencies JPIA

34 Cal.4th 441

The government claim must fairly identify the factual occurrence so the entity can investigate, but need not plead every later legal theory or evidentiary detail.

Andrews v. Metropolitan Transit System

74 Cal.App.5th 597

A materially defective Government Code §913 rejection warning failed to trigger the shorter six-month §945.6 lawsuit period in the circumstances presented.

Wrongful death & survival

Cross v. Pacific Gas & Electric Co.

60 Cal.2d 690

Foundational authority describing California wrongful death as a single proceeding in which the qualifying heirs should join or be joined.

Ruttenberg v. Ruttenberg

53 Cal.App.4th 801

Reinforces the joint, single and indivisible nature of the wrongful death action and the danger of settling while omitting a known statutory heir.

Krouse v. Graham

19 Cal.3d 59

Grief and sorrow from the death itself are not wrongful death damages, while the lost value of society, comfort, care, protection and the relationship can be compensable.

Horwich v. Superior Court

21 Cal.4th 272

The decedent’s comparative negligence can reduce the heirs’ wrongful death recovery. But Proposition 213 does not bar qualifying noneconomic wrongful-death damages merely because the decedent was uninsured when the heirs themselves are neither the uninsured owner nor operator of an involved vehicle.

Quiroz v. Seventh Ave. Center

140 Cal.App.4th 1256

Explains the fundamental distinction between wrongful death, which is a statutory claim belonging to designated heirs, and survival, which continues a cause of action belonging to the decedent.

MedPay, reimbursement & hospital liens

21st Century Insurance Co. v. Superior Court

47 Cal.4th 511

Leading automobile MedPay reimbursement case. Confirms the made-whole doctrine in the MedPay context and treats proportional attorney-fee sharing separately under common-fund principles.

Progressive West Insurance Co. v. Superior Court

135 Cal.App.4th 263

Applies the made-whole rule to automobile MedPay reimbursement while recognizing that sufficiently clear contractual language can alter the default reimbursement priority.

Sapiano v. Williamsburg National Insurance Co.

28 Cal.App.4th 533

Important made-whole authority protecting the insured’s priority to full compensation absent sufficiently specific contrary contractual language.

Lee v. State Farm Mutual Automobile Insurance Co.

57 Cal.App.3d 458

Distinguishes permissible contractual reimbursement from an impermissible assignment of the insured’s personal-injury cause of action.

Parnell v. Adventist Health System/West

35 Cal.4th 595

A Hospital Lien Act lien depends on an underlying debt owed by the patient. The statute cannot manufacture an additional hospital debt after the hospital has accepted contracted payment as full satisfaction.

Long Beach Memorial Medical Center v. Allstate Insurance Co.

95 Cal.App.5th 710 (2023)

A liability insurer with proper Hospital Lien Act notice does not necessarily satisfy the hospital’s statutory interest merely by delivering to the patient or counsel an uncashed settlement check that names the hospital as a joint payee.

Settlement, releases & good-faith allocation

Casey v. Proctor

59 Cal.2d 97

Important Civil Code §1542 authority concerning genuinely unknown personal-injury claims and the intent underlying a purported general release.

Winet v. Price

4 Cal.App.4th 1159

Enforces a knowingly negotiated general release expressly covering unknown claims and specifically waiving Civil Code §1542.

Hess v. Ford Motor Co.

27 Cal.4th 516

Broad boilerplate release language did not discharge a separate tortfeasor where the evidence established that the settling parties did not intend to include that tortfeasor.

Tech-Bilt, Inc. v. Woodward-Clyde & Associates

38 Cal.3d 488

Leading Code of Civil Procedure §877.6 authority defining the framework for determining whether a multiparty settlement was made in good faith.

Frequently asked questions

California Supreme Court decisions control California lower courts on issues of California law. Published Court of Appeal opinions are precedential subject to the Rules of Court governing publication, Supreme Court review, depublication and later authority.

California generally restricts citation of unpublished opinions. Review California Rule of Court 8.1115 and any applicable exception before citation.

The opinion’s precedential and citation status is governed by the current California Rules of Court. Always check the docket and rule before treating the Court of Appeal opinion as controlling authority.

No. The California Supreme Court granted review on March 18, 2026 in Gilliland v. City of Pleasanton, S294539. The opinion has no ordinary binding precedential effect while review is pending, but the Supreme Court’s grant order permits citation for persuasive value and for the limited conflict-of-authority purpose specified in Rule 8.1115(e)(3). The case was fully briefed on August 3, 2026.

No. Horwich v. Superior Court holds that qualifying wrongful-death heirs who are themselves neither the uninsured owner nor operator of an involved vehicle are not barred merely because the decedent lacked the required automobile insurance. The decedent’s comparative negligence is a separate issue and can still reduce the wrongful-death recovery.

Some of California’s governing insurance doctrines—policy interpretation, duty to defend, bad faith, excess coverage, settlement, damages and reimbursement—were developed in cases involving other kinds of insurance. Those rules can nevertheless govern automobile insurance when legally applicable.

Often yes, but always check whether later statutes or cases changed the rule. Automobile financial-responsibility statutes in particular have been amended repeatedly.

No. A summary is a research aid. Read the complete opinion and identify the facts, policy language, statute, procedural posture and actual holding.

Start with the facts, applicable statute and complete policy. Then use case law to determine how California courts interpret those rules and contractual provisions.

A case may turn on one sentence in one endorsement. Different language can produce a different legal result even when the accidents appear similar.

There is no single case for every issue. Wildman is foundational for mandatory permissive-use protection; Waller for policy interpretation; Hartford Fire and related cases for UM/UIM; Comunale, Crisci and Johansen for third-party settlement duties; and Li for comparative fault.

At minimum whenever a cited case receives Supreme Court review, a relevant statute changes, or a new published California Supreme Court or Court of Appeal opinion materially changes one of the doctrines in Guides 01–22.
