Case Summary
50 Exchange Terrace LLC v. Mount Vernon Specialty Insurance Co., decided by Ninth Circuit on March 3, 2025, resulted in a plaintiff win outcome. This case concerns whether a "total pollution exclusion" in a commercial general liability insurance policy barred coverage for claims arising from a "mold and microbial matter" exclusion. The Ninth Circuit held that the "total pollution exclusion" did not bar coverage because the mold exclusion was a specific carve-back to the pollution exclusion, and the policy was ambiguous regarding the scope of the "total pollution exclusion." Therefore, the court affirmed the district court's denial of summary judgment for the insurer. The court held: The "total pollution exclusion" in an insurance policy does not bar coverage for claims related to mold and microbial matter if a separate "mold and microbial matter exclusion" exists and is interpreted as a specific carve-back to the broader exclusion.. Ambiguity in an insurance policy's "total pollution exclusion" clause, particularly when read in conjunction with a more specific mold exclusion, should be construed against the insurer.. The court found that the "total pollution exclusion" was ambiguous because it could be interpreted to exclude all pollution-related claims, or it could be read in conjunction with the mold exclusion to allow coverage for certain types of pollution.. The presence of a specific mold exclusion suggests that the parties intended to carve out mold claims from the general pollution exclusion, rather than to have the total pollution exclusion render the mold exclusion meaningless.. The district court correctly denied the insurer's motion for summary judgment because genuine issues of material fact existed regarding the interpretation of the policy's exclusions.. This decision highlights the critical importance of precise language in insurance policies, particularly concerning exclusions. It reinforces the principle that ambiguous policy terms, especially when specific exclusions interact with broader ones, will be construed against the insurer, potentially expanding coverage for policyholders facing mold-related claims.

For Legal Practitioners
The Ninth Circuit held that a specific 'mold and microbial matter' exclusion functions as a carve-back to a 'total pollution exclusion,' rendering the latter ambiguous and thus construed in favor of coverage for the insured.

It depends. Insurance companies can deny mold damage claims if there is a clear and unambiguous exclusion for mold in the policy.

Practical Implications
For Commercial Property Owners
Commercial property owners with similar insurance policies may have a stronger basis to claim coverage for mold and microbial matter damage, even if their policy contains a broad pollution exclusion, provided there is a specific carve-back for mold.
For Insurance Companies
Insurers may need to re-evaluate the clarity and scope of their pollution exclusions, particularly in relation to specific microbial or mold exclusions, to avoid ambiguity that could lead to unfavorable interpretations in coverage disputes.

An insurance policy is ambiguous if its language can be reasonably interpreted in more than one way. Courts typically interpret ambiguities against the insurer and in favor of the policyholder.
