The punishments handed down by the International Tennis Federation's GrandSlamcommittee could result in a U.S. Open suspension if Williams commits another major violation in any GrandSlam event in 2010 or 2011.
According to the GrandSlam Rule Book, unsportsmanlike conduct when referred to the GrandSlamcommittee can be treated as "aggravated behaviour", which "is flagrant and particularly injurious to the success of a GrandSlam, or is singularly egregious".
