Business and Anti-trust Law

Full-Time / Evening & Weekend MBA
Business Law (BLAW-435-0)
This course is a survey of the basic and fundamental legal concepts that managers and entrepreneurs will be exposed to in public, private and non-profit entities. It is not a surrogate for a law school course (as such the course is not open to law or JD/MBA students) ; it does not delve into subjects of legal procedure (e.g. rules of evidence and rules of civil or criminal procedure). Rather, it covers a variety of legal topics of greatest interest to managers. For example, the course includes instruction on torts, a subject normally covered in a full semester law school course, by focusing on the basics of torts (e.g. negligence, professional negligence (malpractice), and product liability) in a meaningful way so that the student is armed with the ability to identify and analyze tort-related issues going forward. The ten week quarter also includes two topics (contracts and corporations) that are each spread over two weeks of instruction. One week of the quarter is geared to agency law, a subject of great importance in business since under certain circumstances, an employer is automatically liable for the acts of its agents occurring within the scope of their employment. While the majority of class time is spent on civil legal matters (e.g. money damages, equitable relief in the form of injunctions), one week is devoted to a review of criminal law, specifically those crimes that touch U.S. business on a frequent basis (e.g. the Racketeer Influenced and Corrupt Organizations Act (RICO), and Foreign Corrupt Practices Act (FCPA)). Also, due to frequently-expressed interest by students, one week is designed to provide a solid overview of antitrust and intellectual property issues. (Students seeking a deeper dive into these topics should consider taking BLAW 437 upon completion of BLAW 435.)

Issues In Antitrust (BLAW-437-0)
Whether your professional interest is marketing, investment banking, mergers and acquisitions, or distribution channels, a solid exposure to federal and state antitrust laws should be a prerequisite to your academic training at Kellogg. For example, pricing decisions on consumer products cannot be made without a reference to the federal Robinson-Patman Act. Further, state statutes and section two of the federal Sherman Act often guide potentially below cost pricing decisions of products by manufacturers. In addition, termination of dealers, distributors and resellers will most undoubtedly involve consideration of Section 1 of the federal Sherman Act and various state trade regulation laws. The federal Lanham Act regulates issues of trade dress and false advertising. Non compliance with these laws raise many intellectual property issues. On the subject of intellectual property, patent infringement is one of the most highly litigated areas in the federal courts today. Undoubtedly in many of these cases, antitrust counterclaims (e.g., Section 2 of the federal Sherman Act), become more significant than the patent claims that commenced the trial. Finally, the federal Hart-Scott-Rodino Act and Section 7 of the federal Clayton Act guide all merger, acquisition and joint venture activity in the United States. One of the primary analytical questions in any such asset or stock deal is whether the transaction would be approved by the antitrust regulators.
