The Sixth Edition of Insurance Law is characterized by extensive updates that permeate the book. While adhering to the same format, each chapter incorporates recent developments that affect substantive insurance law. Some highlights include the following: The addition of text discussing the recent decision Golden Gate Restaurant Association v. City & County of San Francisco, in which the Ninth Circuit Court of appeals upheld San Francisco's "play or pay" ordinance, which requires employers with employees covered by the ordinance to make "required health care expenditures to or on their behalf." The case has potentially far-reaching implications for ERISA preemption jurisprudence. Material on the Genetic Information Nondiscrimination Act of 2008. Addition of the 2009 California Supreme Court's decision Delgado v. Interinsurance Exchange of the Automobile Club of Southern California which has the potential to significantly affect the scope of an insurer's duty to defend. Coverage of New York's 2008 amendment to Insurance Law Section 3420 which provides for a nuanced approach to the conventional notice-prejudice rule commonly used in most other states. More material on various aspects of the tripartite relationship. Throughout the new edition, the addition of cases is done in the context of the same format. Where cases are deleted, the substantive points are generally preserved in notes following cases.
