The sticking point is what happened after the claim came in. Travelers says it tendered the defense to MESA on August 12, 2025, and MESA responded on September 15, 2025 in what appeared to be an acceptance. Travelers argues it was not a full one. The complaint quotes MESA’s letter as reserving “all (and waives none) of its rights under the Policy and applicable law, including the right to later raise other terms, conditions, and exclusions in the Policy as appropriate,” and stating that all rights are “hereby expressly reserved.” (The quoted letter refers to the insurer by its own initials, “MUSIC.”)
