An internal investigation of the National Basketball Players Association’s business practices under executive director G. William Hunter conducted by Paul, Weiss, Rifkind, Wharton & Garrison has cleared the former federal prosecutor of illegal activity, but recommends potential changes to the union’s leadership and policies.

The Paul Weiss probe began nine months ago amid a power struggle for control of the NBPA, following a five-month lockout of players by league management during collective bargaining negotiations. A six-member committee of players retained Paul Weiss litigation cochair Theodore “Ted” Wells Jr., partner David Brown, and associate Amy Gold after the U.S. attorney’s office in Manhattan began an investigation of its own into how the union conducted its affairs under Hunter’s stewardship.
