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.
Permanent Court of Arbitration
Arbitration between two states takes place when two member states of the PCA decide to submit a dispute for arbitration to a PCA Tribunal. The Tribunal consists of 5 arbitrators, two of which are selected by each party to the arbitration (and one of whom may be a national of the party concerned). The four arbitrators choose the fifth and presiding arbitrator.
