Class Actions and Derivative Lawsuits


The Litigation Department at Arnon, Tadmor-Levy has a unique specialization in class actions, including experience that is unparalleled in Israel in representing large corporations defending against class actions. Our clients come from areas such as banking, insurance, securities, telecommunications, aviation and transportation, consumer rights and product liability, mass torts, environmental quality, data repositories and privacy, and more.

Representing defendants in class action proceedings involves elements related both to the substantial legal claims alleged, and the unique procedural platform of a class action lawsuit. Our Litigation Department has a wealth of experience in representing defendants in this area.

Arnon, Tadmor-Levy was one of the first major firms to represent defendants in class actions in the 1990s, when this was an emerging and innovative field in Israeli law. After many years of accumulating experience in this area, our firm remains a leader in representing defendants in class actions. To date, we have represented defendants in hundreds of proceedings in a wide range of fields, including consumer issues, advertising, insurance, banking, product liability, labor law, competition law, communications law, aviation law, environmental law, education law, internet law, and more. To the best of our knowledge, we have represented the largest number of proceedings handled by any single law firm in Israel.

Our experience and standing in this field are reflected both in the number and stature of our clients in this area, as well as in Israeli and international rankings, in which we have been rated in the highest quality category for many years. Our market position is a result of the reputation we have earned among companies who are frequently defendants in such proceedings, as well as among law firms specializing in this field, including those leading in representing plaintiffs in class actions, and the recognition of our expertise by the courts.

In some of these proceedings, we represent several competing defendants (subject to relevant ethical and relevant antitrust rules), which demonstrates the trust and confidence our clients have in our capabilities and professional integrity.

In parallel, our firm also specializes in derivative lawsuits, a field that has gained momentum in recent years, especially after the establishment of the Economic Department in the Tel Aviv District Court and recently in the Haifa District Court. Our Litigation Department represents both companies who are involved as plaintiffs in a derivative lawsuit process, as well as managers and office holders who are sued in such lawsuits.

In recent years, we have represented many commercial companies, including banks and insurance companies, in derivative proceedings, as well as before independent claims committees that sometimes act on behalf of a company to examine a request for a derivative lawsuit filed against it.

The field of derivative lawsuits and economic class actions requires legal and economic expertise, in which our Litigation Department has a significant comparative advantage, and a close professional acquaintance with the leading economic experts in providing opinions in derivative and representative proceedings.
