April 16, 2003 PUBLICATIONThe Current State of Comparative Bad Faith

In most every jurisdiction, the basis for a claim of insurer bad faith is the recognition of a duty of good faith and fair dealing inherent in any contract of insurance. See, e.g., Boston Old Colony v. Gutierrez, 386 So. 2d 783 (Fla. 1980). The focus in such cases is usually the question of whether or not the insurer has violated that duty. Inevitably, the question arises as to whether or not the actions of the insured can be considered bad faith and, if so, whether such actions can be raised as an affirmative defense to a claim of insurer bad faith.

October 19, 1999 PUBLICATIONThe Duty of Good Faith: Continuing Into Litigation

First-party bad faith cases are typically based on conduct or events (e.g., settlement offers, investigations and evaluations) occurring during the time period after a claim is made but before any litigation is commenced. Once a breach of contract or declaratory action is filed, it is generally understood that the insured and insurer stand in an adversarial relationship which presumably entitles each party to zealously pursue its litigation tactics and strategy. Thus, courts generally will not permit an insurer's litigation conduct to be admitted as evidence of bad faith. Over the years, however, a significant number of courts have held an insurer owes a continuing duty of good faith to an insured throughout the litigation process and, therefore, an insurer's post-filing conduct may be admitted as evidence of bad faith. This article is a brief review of some of the leading cases addressing the continuing duty of good faith and its ramifications affecting insurance companies and defense counsel.

August 17, 1999 PUBLICATIONMultiple Claims Exceeding the Policy Limits

When courts and state legislatures expand the duties owed by liability insurers to insureds there is a commensurate expansion of the grounds for extracontractual claims. One area of expansion has been in cases involving multiple third-party claimants - with liability clear and damages exceeding the policy limits. These cases make difficult issues for claims professionals.
