A selection of Asaf’s cases include acting for:

  • Representing and advising Maccabi Healthcare Services, one of Israel’s largest healthcare service providers, in a range of disputes with hospitals, health professions, patients and government agencies, including class actions, health policy matters, all matters concerning drugs and health technologists, including regulatory aspects and the inclusion of drugs in the national health basket. For example:
    • A class action valued at one billion NIS which was brought in connection with a change of formulation of a drug supplied by Maccabi. The plaintiffs claimed that the change of formulation resulted in patients experiencing various adverse reactions
    • A class action raising fundamental questions regarding the use of generic drugs by Maccabi specifically, and in Israel’s public health system as a whole.
    • A class action concerning the sending of text messages (“spam messages”).
    • Several class actions concerning payments that Maccabi is permitted to collect from its insureds.
    • Several class actions claiming discrimination on the ground of gender or sexual orientation. These actions raise certain questions, such as whether it is permissible that medical insurance cover expenses for egg donor procedures that are performed abroad for insured women, so that homosexual partners cannot enjoy this benefit; or whether it is permissible that medical insurance will grant services and benefits relating to pregnancy and childbirth to women only.
    • A class action dealing with the question as to whether linkage differentials and interest should be added to the various payments that Maccabi refunds to its members.
    • Application to certify a derivative action, on behalf of Maccabi, against a number of private insurance companies. Maccabi’s position was accepted by the Supreme Court, which held that a member of a Health Maintenance Organization (HMO) (Kupat Holim) is not entitled to file a derivative action on behalf of the HMO, and the claim was accordingly dismissed in limine.
    • A claim filed by Maccabi against the pharmaceutical companies, Sanofi S.A. and Sanofi-Aventis Israel Ltd., seeking compensation for damages caused to Maccabi due to the defendants’ conduct, which resulted in a delay in the entry to the market of a generic alternative to the pharmaceutical drug, Plavix, that is marketed by them. As argued by Maccabi, such delay resulted in it having to pay a much higher price for Plavix than it should have paid, had the generic product entered the market sooner.
    • Various petitions being deliberated before the High Court of Justice, on an array of issues, such as: the reform in the mental health system, the availability and quality of the rehabilitation services in the north and south of Israel, as opposed to those provided in the central area, the legality of the amendment to the law that limits the possibility of doctors being able to provide certain medical services on a private basis and the legality of regulations governing the eligibility of non-residents who have permission to stay in Israel, to receive health care services.
