Oakley's attorney in the case is Alex Spiro, who successfully defended Hawks forward Thabo Sefolosha following his 2015 arrest outside a NY nightclub. Dolan was criticized by many current and former players for making those claims. He has said that he felt targeted by security.
The incident earned Oakley, who played ten seasons with the Knicks, a lifetime ban from the Garden, which was later lifted.
National Basketball Association commissioner Adam Silver and Charlotte Hornets owner Michael Jordan - a former teammate of Oakley with the Chicago Bulls - met with Dolan and Oakley in hopes of ending the dispute. Oakley played 10 of his 19 National Basketball Association seasons with the Knicks, from 1988-98.More news: US employers add modest 138K jobs; rate dips to 4.3 percent
