This paper analyzes the current antitrust issues, mainly focusing on the agribusiness Bayer-Monsanto merger. It examines the background, related laws with respect to the United States and the European Union, different point of views, and impacts set forth by the Bayer-Monsanto merger; following with a case commentary. This commentary interprets the merger as an illegal decision and higher authorities should have scrutinized and weighted the deal more carefully. Numerous things have changed since the establishment of the regulations regarding antitrust issues; whether this merger could be a possible extension for an update on the antitrust law is something that could be taken into consideration.
