Spectrum Sports, Inc. v. McQuillan

Case Date: 05/06/1993

Spectrum Sports, Inc. v. McQuillan, 506 U.S. 447 (1993) was a case in which the Supreme Court of the United States rejected the assertion that attempted monopolization may be proven merely by demonstration of unfair or predatory conduct. Instead, conduct of a single firm could be held to be unlawful attempted monopolization only when it actually monopolized or dangerously threatened to do so. Thus, the Court rejected the conclusion that injury to competition could be presumed to follow from certain conduct. The causal link must be demonstrated.
