This Simpson Thacher & Bartlett LLP memorandum discusses court decisions relating to defense cost reimbursements, property damage under general liability policies, anti-assignment clauses and the validity of an arbitration provision in a multi-party reinsurance treaty. It also discusses a South Carolina statute that defines faulty workmanship as an occurrence in commercial general liability policies covering construction work and a Delaware court ruling on the impact of a "lot or batch" clause in a commercial umbrella liability policy on the policy's definition of the term "occurrence." Court rulings on the scope of removal under the Class Action Fairness Act (CAFA), the application of a pollution exclusion to defective drywall claims and reimbursement of e-discovery costs are also detailed.
