On January 10, 2019, an amendment to the Restrictive Trade Practices Law, now known under its new name, the “Economic Competition Law”, entered into force. Michal Rothschild, head of Antitrust & Competition Department and Arik Brenneisen, a partner in the department, summarized the main changes to the law, which expand the powers of the Competition Commissioner. The main changes are to the definition of what constitutes a “monopoly”, certain provisions regarding merger control, and the sanctions for violating the provisions of the law.
