Double jeopardy clause occurs when a person is put on trial for an offense of which he has already been put on trial before. United States Constitution, states that no <em><u>"person be subject for the same offense to be twice put in jeopardy of life or limb..."</u></em>
This can only apply if the accused has already gotten a valid acquittal from a law court or conviction within the same jurisdiction. If this occurs, then the government or prosecutor cannot retry the accused/defendant.
Therefore, Frank Palko believed that double jeopardy would apply in his case because he was tried twice for the same crime.
