 Question: can you have a heart attack from laughing Context: Mistrials are generally not covered by the double jeopardy clause. If a judge dismisses the case or concludes the trial without deciding the facts in the defendant's favor (for example, by dismissing the case on procedural grounds), the case is a mistrial and may normally be retried. Furthermore, if a jury cannot reach a verdict, the judge may declare a mistrial and order a retrial as was addressed in United States v. Josef Perez, 22 U.S. 579 (1824). When the defendant moves for a mistrial, there is no bar to retrial, even if the prosecutor or judge caused the error that forms the basis of the motion. An exception exists, however, where the prosecutor or judge has acted in bad faith. In Oregon v. Kennedy, 456 U.S. 667 (1982), the Supreme Court held that ``only where the governmental conduct in question is intended to 'goad' the defendant into moving for a mistrial may a defendant raise the bar of double jeopardy to a second trial after having succeeded in aborting the first on his own motion.''
 Question: can a prosecutor refile charges after a mistrial Context: The gold standard was temporarily abandoned during the First World War and definitively abolished on April 10, 1933. At the outbreak of the Second World War, the exchange rate to the U.S. dollar was fixed at C$1.10 = US$1.00. This was changed to parity in 1946. In 1949, sterling was devalued and Canada followed, returning to a peg of C$1.10 = US$1.00. However, Canada allowed its dollar to float in 1950, whereupon the currency rose to a slight premium over the U.S. dollar for the next decade. But the Canadian dollar fell sharply after 1960 before it was again pegged in 1962 at C$1.00 = US$0.925. This was sometimes pejoratively referred to as the ``Diefenbuck'' or the ``Diefendollar'', after the then Prime Minister, John Diefenbaker. This peg lasted until 1970, after which the currency's value has floated.
 Question: has the canadian dollar ever been higher than the us dollar Context: Another form of virginity testing involves testing for laxity of vaginal muscles with fingers (the ``two-finger test''). A doctor performs the test by inserting a finger into the female's vagina to check the level of vaginal laxity, which is used to determine if she is ``habituated to sexual intercourse''. However, the usefulness of these criteria has been questioned by medical authorities and opponents of virginity testing because vaginal laxity and the absence of a hymen can both be caused by other factors, and the ``two-finger test'' is based on subjective observation. In virginity tests, the presence of a hymen is often used to determine if a woman is a virgin.
