Plea bargaining in the United States
The constitutionality of plea bargaining was established by "Brady v. United States" in 1970, although the Supreme Court warned that plea incentives which were sufficiently large or coercive as to over-rule defendants' abilities to act freely, or used in a manner giving rise to a significant number of innocent people pleading guilty, might be prohibited or lead to concerns over constitutionality. "Santobello v. New York" added that when plea bargains are broken, legal remedies exist.
Federal Arbitration Act
Once an award is entered by an arbitrator or arbitration panel, it must be "confirmed" in a court of law; and once confirmed, the award is reduced to an enforceable judgment, which may be enforced by the winning party in court, like any other judgment. Under the FAA, an award must be confirmed within one year, and any objection to an award must be challenged by the losing party within three months. An arbitration agreement may be entered "prospectively" (ie., in advance of any actual dispute), or may be entered into by the disputing parties once a dispute has arisen.
