A federal appeals court has ruled against an Ohio lawyer who alleged the National Basketball Players Association and the National Basketball Association acted together to wrongfully prevent him from taking a certification exam required for prospective NBA agents.

Citing “labor exemptions” to antitrust laws that preclude the attorney’s Sherman Act claims, as well as the attorney’s “conclusory” statements and allegations, the U.S. Court of Appeals for the Sixth Circuit tossed out Cleveland-based lawyer Rosel Hurley III’s lawsuit lodged against both the NBPA and the NBA.
