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.
Arbitration clause
In the United States, the federal government has expressed a policy of support of arbitration clauses, because they reduce the burden on court systems to resolve disputes. This support is found in the Federal Arbitration Act, which permits compulsory and binding arbitration, under which parties give up the right to appeal an arbitrator's decision to a court. In "Prima Paint Corp. v. Flood & Conklin Mfg. Co.", the U.S. Supreme Court established the "separability principle", under which enforceability of a contract must be challenged in arbitration before any court action, unless the arbitration clause itself has been challenged.
