Fifth Amendment: Due Process

The Fifth Amendment protects against abuse of government authority in a legal procedure. Its guarantees stem from English common law which traces back to the Magna Carta in 1215. For instance, grand juries and the phrase "due process" both trace their origin to the Magna Carta.

Double Jeopardy: The fifth amendment refers to being put in "jeopardy of life or limb." The clause, however, has been interpreted as providing protection regarding "every indictment or information charging a party with a known and defined crime or misdemeanor." The clause, it has been held, does not prevent separate trials by different governments, and the state and federal governments are considered "separate sovereigns". Therefore, one may be prosecuted for a crime in a state court, and prosecuted for the same crime in another state, a foreign country, or (most commonly) in a federal court.

Once acquitted, a defendant may not be retried for the same offense: "A verdict of acquittal, although not followed by any judgment, is a bar to a subsequent prosecution for the same offense." Acquittal by a jury is generally final and cannot be appealed by the prosecution. An acquittal in a trial by judge (bench trial) is also generally not appealable by the prosecution. A trial judge may normally enter an acquittal if he deems the evidence insufficient for conviction. If the judge makes this ruling before the jury reaches its verdict, the judge's determination is final. If, however, the judge overrules a conviction by the jury, the prosecution may appeal to have the conviction reinstated. Additionally, although a judge may overrule a guilty verdict by a jury, he or she does not have the same power to overrule a not guilty verdict.

Defendants may not be retried following conviction except in limited circumstances when the judge sees fit and proper. Bribing a judge to get an acquittal is not valid because the party acquitted has prevented themselves from being placed into "jeopardy" to begin with. The defendant may not be punished twice for the same offense. In certain circumstances, however, a sentence may be increased. It has been held that sentences do not have the same "finality" as acquittals, and may therefore be reviewed by the courts. Sentence increases may not, however, be made once the defendant has already begun serving his term of imprisonment. If a defendant's conviction is overturned on procedural grounds, the retrial may result in a harsher penalty than the original trial. The only exception is that the prosecution may not seek capital punishment in the retrial if the jury did not impose it in the original trial.

Per text in the Constitution: "No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offense to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation."
