Court Sharpens Causation Standard in All-Risk Policies in Church Mutual Case

Why It Matters

The clarified causation rule expands coverage obligations, potentially raising claim costs for insurers. Simultaneously, the expanded class‑action scope threatens significant financial liability for insurers that depreciate labor in ACV calculations.

Key Takeaways

• Excluded cause must be sole cause for all‑risk exclusion.
• Decision follows 1973 Avis v. Hartford precedent.
• Could raise insurers’ claim payouts on mixed‑cause losses.
• Opens door to multi‑state labor depreciation class action.
• Church Mutual may face broader liability across ten states.

Pulse Analysis

All‑risk property policies have long been subject to a nuanced causation analysis, but the 4th Circuit’s recent opinion sharpens that framework. By anchoring the exclusion test to a "sole cause" requirement, the court aligns modern practice with the 1973 Avis v. Hartford decision, which held that any covered cause contributing to loss defeats an exclusion. This clarification eliminates the ambiguous "predominant cause" standard, meaning insurers must now honor claims when a covered peril participates, even if an excluded factor is also present. The shift promises broader claim coverage and forces underwriters to reassess policy language for mixed‑cause events.

The ruling arrives amid a wave of litigation targeting insurers’ treatment of labor depreciation in actual cash‑value (ACV) settlements. The 6th Circuit’s decision to allow a potential ten‑state class action against Church Mutual underscores growing scrutiny over whether insurers can deduct labor costs when statutes prohibit such depreciation. Recent cases against State Farm and Trumbull illustrate a pattern: courts are increasingly siding with policyholders who argue that labor is a non‑material expense that should not reduce payouts. For Church Mutual, the combination of a stricter causation rule and exposure to a multi‑state class suit could translate into substantially higher reserve requirements and settlement costs.

Industry observers expect insurers to respond by tightening exclusions, clarifying ACV calculation methods, and possibly revising pricing to reflect the heightened risk. Reinsurance markets may also adjust terms, demanding more explicit language around mixed‑cause losses and labor depreciation. For businesses, especially those with all‑risk coverage such as churches, the developments highlight the importance of reviewing policy wordings and ensuring that exclusions do not inadvertently limit recovery. Staying informed about evolving case law can help risk managers negotiate better terms and avoid unexpected shortfalls in claim payments.
