    The firm highlighted that Van Horn has represented clients in significant antitrust cases, including defending against price-fixing claims, achieving dismissals of exclusive dealing allegations, and negotiating with enforcement agencies in cartel and merger matters. His commercial litigation work has also encompassed disputes involving hedge funds, private equity, and complex financial instruments.

    “Shaun’s return represents a strategic expansion of our in-demand capabilities at a time when regulatory scrutiny and antitrust have reached unprecedented levels,” said Co-Managing Partners Ishan Bhabha and Randy Mehrberg in a statement. They emphasized that his combined expertise in intellectual property and antitrust litigation will enhance the firm’s ability to serve clients facing challenging regulatory environments.

    The firm’s Antitrust and Competition Law Practice leaders also pointed to the growing importance of Van Horn’s skill set. Per a statement from Practice Co-Chairs Doug Litvack and David Singer, his work defending clients against competition claims and helping secure regulatory approvals strengthens the team during a time of rising antitrust activity.

    Jenner & Block’s Antitrust Practice has continued to secure major outcomes for its clients. The firm noted that this year it won three significant victories for Hyatt Hotels Corporation in federal class actions, where plaintiffs had alleged that the company participated in practices leading to inflated hotel rates.
