At A Glance:
Summary: This excess insurer collateral estoppel defense decision shows why prior coverage rulings involving a primary insurer do not automatically resolve a later Insurance Law § 3420 claim against an excess carrier.
The Appellate Division, Second Department held that the Disano’s primary insurer (First Mercury Insurance Company) could not obtain dismissal of an Insurance Law § 3420 action by relying on earlier coverage rulings concerning the demolition company’s excess insurer (Scottsdale) because those rulings did not conclusively resolve Scottsdale’s separate excess-coverage obligations.
The Court’s decision is useful for claims adjusters and litigators because it reinforces that collateral estoppel requires an issue to have been actually litigated, squarely addressed, and specifically decided, especially when a later coverage action concerns different parties, policies, and claims.
Court: Appellate Division, Second Department
Decision Date: June 4, 2025
Case: Harco Constr. LLC v Scottsdale Ins. Co., 2025 NY Slip Op 03311 [239 AD3d 610] (2d Dept 2025)
Topic: Insurance Law § 3420, Collateral Estoppel
The Court’s Position:
The Second Department affirmed the motion court’s denial of the demolition company’s primary insurer’s (First Mercury Insurance Company) motion to dismiss an Insurance Law § 3420 coverage action, commenced by the general contractor, Harco Construction, LLC, arising from the collapse of a building and adjoining scaffold. Scottsdale argued that prior rulings involving the demolition contractor’s primary insurer (First Mercury), and the “work height” exclusion barred the new action, but the Court held that the prior decisions did not conclusively resolve Scottsdale’s separate excess coverage obligations.
What Happened:
The demolition contractor (Disano Demolition) was on a demolition site and cut into a building’s elevator shaft, triggering a collapse. The general contractor (Harco Construction, LLC) sought coverage as an additional insured from Disano’s primary insurer (First Mercury Insurance Company), and excess insurer (Scottsdale Insurance Company). The excess policy followed forms of the primary insurer.
In a prior action, commenced by Harco and the building owner, against Disano and its primary (First Mercury) and excess insurer (Scottsdale). The primary insurer (First Mercury) denied coverage based on a “work height” exclusion. The motion court upheld the primary insurer’s (First Mercury) disclaimer. The Second Department, however, reversed in part, ruling that the primary insurer’s (First Mercury) denial to Harco was untimely under Insurance Law § 3420(d) and therefore estopped. The excess insurer (Scottsdale) was not a party to the appeal.
The appeal concerned an action by the general contractor, its insurer, and the building owner against Disano and Scottsdale insurance under Insurance Law § 3420. They sought satisfaction of judgments against the demolition subcontractor (Disano), and a declaration that the excess insurer (Scottsdale) had a duty to indemnify the general contractor. The excess insurer (Scottsdale) moved to dismiss the complaint under CPLR 3211(a), citing that documentary evidence and collateral estoppel precluded the action.
The Second Department held that the motion court properly denied Scottsdale’s motion to dismiss on both documentary-evidence and collateral-estoppel grounds. The Court reasoned that its prior decision did not conclusively resolve the excess insurer’s (Scottsdale) coverage obligations. They focused on the primary insurer (First Mercury), instead. The Court further concluded that the issues in the prior action were not identical, the parties were different, and the excess insurer (Scottsdale) failed to show that any issues were “actually litigated and specifically decided.”
The Court also rejected Scottsdale’s CPLR 3211(a)(1) documentary evidence argument because the prior orders did not “utterly refute” the plaintiffs’ claims or conclusively establish the excess insurer’s (Scottsdale) defense as a matter of law.
Key Language from the Decision:
The Decision:
The Second Department held that the motion court properly denied the excess insurer’s (Scottsdale) motions on both the collateral estoppel and documentary evidence grounds of their motion to dismiss.
From a Claims Perspective:
Do not assume that estoppel or disclaimer defenses from another insurer carry over to your claims file. Additionally, timeliness of disclaimer under Insurance Law § 3420(d) remains a critical battleground.
What to Know:
This ruling reinforces that each layer of insurance stands on its own. Coverage litigation is rarely “one-and-done.” An excess insurer cannot rely on a primary insurer’s victory to short-circuit its own coverage obligations.
Strategic Insight:
Collateral Estoppel Is Not a Shortcut
Insurers must prove that issues were actually litigated and decided.
Documentary Evidence Must Conclusively Resolve the Defense
Prior decisions concerning different insurers cannot support a CPLR 3211(a) motion unless they clearly resolve the same issue for the same party.

Authority:
The Court relied on New York’s standards for dismissal under CPLR 3211(a)(1) and CPLR 3211(a)(5). For documentary evidence, the Court applied the rule that dismissal is proper only when the documents “utterly refute” the complaint’s allegations and conclusively establish a defense as a matter of law. For collateral estoppel, the Court applied the rule that the issue in the second action must be identical to an issue that was actually litigated, necessarily decided, and material in the first action.
