bonds's trial was set for march 2, 2009, but delayed by appeals, after the judge excluded drugs tests and other evidence that could not be specifically tied to bonds without the testimony of greg anderson, who is alleged to have provided steroids to barry bonds when he was bonds personal trainer and linked to bay area laboratory co-operative (balco). law professor peter keane called the prosecutors' move a blunder, although an account by another published attorney disagreed. in june 2010, however, the 9th circuit u.s. court of appeals ruled that the evidence should be excluded. on august 7, 2010, it was reported that u.s. district judge susan illston of san francisco had rescheduled the trial for march 21, 2011. on friday, december 17, 2010, it was reported that attorneys for bonds, citing the appeals court ruling, filed papers asking the judge to forbid testimony of current and former baseball players linked to balco or the steroids scandal, and not to permit use of anderson's drug ledgers and calendars, as well as other documents from balco which the prosecution was seeking to use at the trial in spite of the appeals court ruling.
