This is an exception to the double jeopardy clause of the U.S. Constitution, which prohibits a person from being tried twice for the same offense. In a 2.06 Explanatory: Previous Trial, the defendant does not have to be the same person as in the previous trial, and the new trial may be conducted even if the previous trial resulted in a conviction. The different types of 2.06 Explanatory: Previous Trial include mistrials, hung juries, and appeals.
