About

Provided by Zioni Pillersdorf Phillip Advocates

Zioni Pillersdorf Phillip is a leading Israeli boutique in plaintiff-side class actions, recognised for its strategic focus, cross-border sophistication and ability to secure meaningful rulings against some of the world’s largest corporations.

The practice concentrates on complex, precedent-setting matters involving consumer protection, privacy, competition and deceptive practices.

The team represents plaintiffs in high-profile class actions against Google, Apple, WhatsApp, Tesla, OpenAI, Discord, DeepSeek and others, regularly litigating against top-tier Israeli defence firms and international counsel.

Many cases involve jurisdictional disputes, foreign choice-of-law clauses and service abroad.

Notable rulings include:

  • WhatsApp – defeating a jurisdictional challenge based on a California choice-of-law clause, with the court holding that the exclusion of non-residents under the CCPA may violate Israeli public policy.
  • Apple – establishing that service on Apple’s Israeli affiliates constitutes valid service on Apple Inc., followed by a court-approved NIS 10 million settlement.
  • OpenAI – successfully opposing dismissal for lack of jurisdiction, with the court rejecting reliance on California incorporation and terms of use.

The practice is led by Shaul Zioni (ranked by Chambers) and Eli Pillersdorf, each with over 20 years’ experience
