The Supreme Court has determined that immigrants detained as arriving aliens or as mandatory detainees due to certain criminal convictions are not entitled to bond hearings under the statutory language which authorizes their detention. In addition, discretionary detainees who are not granted bond because they cannot prove they are not a flight risk or danger to the community are not entitled to periodic reviews of their detention. The Court remanded the case to the Ninth Circuit to address whether the due process protections of the Constitution mandate bond hearings for these detainees.
