A European-style date on a construction contract sparked a coverage denial - and now a federal lawsuit is seeking treble damages.
JHG, LLC filed suit on February 17 against Mesa Underwriters Specialty Insurance Company ("MUSIC") in the US District Court for the Southern District of Texas, alleging the insurer wrongfully refused to defend a construction claim, misrepresented key facts, and then quietly reversed course - without ever making things right.
The dispute centers on a commercial general liability policy MUSIC issued to JHG, effective July 15, 2022 through July 15, 2023. JHG began work on a construction project for Fort Vale, Inc. in January 2023, squarely within the policy window. When Fort Vale brought an action against JHG in July 2024, JHG notified MUSIC the following month and asked for a defense.
What came next, according to the suit, was silence - followed by a denial built on what JHG calls a clear factual misrepresentation.
Both parties had signed the construction contract using a European date format: day/month/year. So "11/1/23" meant January 11, 2023. MUSIC, however, read it as November 1, 2023, placing the contract start date outside the policy period and giving itself grounds to walk away. JHG says the contract language and other documents in MUSIC's hands made the January start date obvious.
MUSIC also took the position that its policy did not cover work that started during the policy period but was completed afterward. JHG counters that no such exclusion exists - the policy only excluded work performed in whole or in part before the policy began.
With no defense forthcoming, JHG hired its own lawyers and spent roughly $100,000 in court costs and attorney's fees fighting the Fort Vale case.
The situation shifted in September 2025. After JHG's insurance counsel issued a formal demand under the Texas Prompt Payment of Claims Act, MUSIC reversed course. The insurer retained a law firm to defend JHG, approved a mediated settlement with Fort Vale in December 2025, and paid it in full. But MUSIC never issued a reservation of rights, never filed a declaratory judgment action, and has not reimbursed JHG for the legal costs it shouldered while MUSIC sat on the sidelines.
That sequence, JHG argues, estops MUSIC from denying coverage altogether.
JHG is now seeking full reimbursement of its defense costs, 18% statutory interest dating to November 2024 under the Prompt Payment of Claims Act, and treble damages under the Texas Insurance Code for what it describes as knowing unfair and deceptive insurance practices - including misrepresenting policy terms and failing to conduct a reasonable investigation.
For claims professionals, the case is a reminder that documentation must be reviewed with care, statutory deadlines carry real teeth in Texas, and defending a claim without reserving rights can foreclose coverage defenses entirely.
No determination on the merits has been made. The case is JHG, LLC v. Mesa Underwriters Specialty Insurance Company, Case No. 4:26-cv-01250, in the Southern District of Texas.
