He joined the firm from the Massachusetts Attorney General's Office (AGO), where he served in the Office's Antitrust Division. In that role, he worked hand-in-hand with enforcers from the U.S. Department of Justice (DOJ), the Federal Trade Commission (FTC), and the attorney general offices of nearly every U.S. state and territory to investigate and litigate merger, monopolization, and cartel matters.
Mr. Taeschler is an experienced litigator and antitrust lawyer. He leverages his private practice and Federal Trade Commission experience to advise and represent clients on all aspects of antitrust law across a diverse range of industries. Mr. Taeschler’s varied practice covers class action litigation, competitor litigation, merger reviews and investigations, conduct investigations, and antitrust counseling. He represents clients spanning several industries, including the technology, healthcare, sports, pharmaceutical, financial services, automotive, and optical industries.

In addition, he serves as an adjunct professor at Brooklyn Law School.
Description
In the last several years, a growing number of states have enacted or are considering enacting various legislative and regulatory changes that would increase antitrust scrutiny for a variety of business activities. These state-level regulations are similar to the federal Hart-Scott-Rodino Act (HSR Act) and require parties to certain transactions to seek merger clearance from state authorities prior to closing.
To date, 15 states, including California and New York, have HSR-like notice regimes. While most of these laws are directed at healthcare-specific transactions, it is expected that state antitrust scrutiny will extend to other sectors in the future.
To encourage states to impose transaction requirements that are consistent with existing federal HSR obligations, in July 2024, the Uniform Law Commission (ULC) approved the Uniform Antitrust Pre-Merger Notification Act. The Act is intended as model legislation for states to use to implement pre-merger filing regimes and according to the ULC, creates a simple, non-burdensome mechanism for state attorneys general to receive access to HSR filings at the same time as the federal agencies and subject to the same confidentiality obligations.
State antitrust laws add an additional layer of compliance requirements for merging parties to consider, and they are expected to increase transaction timelines, costs, and risks. It is imperative that counsel and merging parties comply with state antitrust requirements as noncompliance may result in substantial fines or enforcement actions.
Listen as our panel of antitrust experts reviews the current framework of state antitrust laws and provides guidance for navigating state-specific merger notification regimes.
