McCleery v. Allstate Ins. Co., 37 Cal. App. 5th 434

Background

Plaintiffs are ~1,550 property inspectors who sued insurers (Allstate, Farmers) and service companies (CIS, AFS, PMG) claiming joint-employment and violations of wage-and-hour laws (minimum wage, overtime, meal/rest breaks, expense reimbursement, wage statements) and UCL violations.
Plaintiffs sought class certification and proposed to prove liability and quantify damages via an anonymous, double-blind statistical survey designed and analyzed by Dr. John Krosnick sampling class members.
On first appeal this court remanded to the trial court to evaluate the sampling plan; on remand the trial court found common issues as to employer status but concluded the survey-based trial plan was "unworkable" because it failed to address individualized issues and deprived defendants of meaningful defenses and cross‑examination, and denied certification.
Plaintiffs argued the survey was scientifically valid and that liability could alternatively be proven by common documentary evidence of joint‑employer control and theories of vicarious liability, agency, conspiracy, or alter ego.
The Court of Appeal affirmed the denial, holding that even if common proof could show employer status, liability for overtime, breaks, and other wage claims depended on individualized facts (hours, which insurer work applied, subcontracting, dates), and the anonymous survey did not provide a fair, manageable method to establish liability or permit effective defense.
The court emphasized manageability and defendants’ right to confront and challenge evidence; it declined to permit trial to proceed solely on expert testimony based on anonymous survey data.

Issues

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether class certification is appropriate where plaintiffs propose to prove liability and damages classwide by anonymous statistical survey	Krosnick survey can validly establish common proof of liability and damages across class; scientific sampling substitutes for individual proofs	Survey omits key liability questions (which insurer, joint‑employment facts), invites recall error, anonymity prevents cross‑examination and verification, and cannot apportion employer liability	Denied: survey may be scientifically sound but is inadequate as a trial plan—unmanageable and unfair; certification properly denied
Whether common proof predominates for employer/joint‑employer liability so class treatment is proper	Plaintiffs: common documentary evidence and uniform policies show defendants were joint employers and thus liable classwide	Defendants: inspectors worked variably (multiple insurers, subcontracting), so liability inquiry requires individual factfinding	Court: common issues as to status may exist, but status alone does not establish liability for overtime/breaks; individualized inquiries predominate for proving actual violations
Whether a liability-only Phase I (classwide) with Phase II individual claims/process is a superior method	Plaintiffs: establish liability classwide then resolve individual damages/claims via questionnaires and streamlined trials; superior to individual suits	Defendants: Phase II would still require many contested individual proceedings; defendants cannot meaningfully defend or reduce damages based on survey-only liability finding	Court: liability-phase approach (as in Duran) is not manageable or superior here; would not permit defendants adequate means to challenge or reduce liability/damages
Whether expert may testify to classwide liability based on anonymous survey data (hearsay/authentication/cross-examination concerns)	Plaintiffs: expert opinion based on survey data is admissible and defendants can conduct their own studies	Defendants: expert reliance on anonymous, unverifiable hearsay prevents effective impeachment and denies confrontation; details of underlying data are essential	Court: Expert may rely on survey methodology generally, but trial cannot rest solely on anonymous survey-backed expert testimony that forecloses cross-examination and verification; certification denied
