premise: A US federal judge has halted the war crimes trial of an Australian terror suspect detained in the US naval base at Guantanamo Bay, Cuba, the New York Times reported on Wednesday.
  In her ruling, US District Judge Colleen Kollar-Kotelly suspended for several months the US military's plan to resume the trial of David Hicks, the Aussie charged with fighting for the Taliban in Afghanistan.
  The move follows a request made by his lawyers, according to the report.
  Kollar-Kotelly cited the Supreme Court's decision last week to review the legality of the military commissions being used to try Guantanamo detainees with war crimes.
  The court ruling concerns the case of Salim Ahmed Hamdan, who was a driver for Osama bin Laden and has been accused of participating in terrorist activities.
   What led to the review of the legality of the situation?
hypothesis: plan to resume the trial of David Hicks
