Double jeopardy exists when the following requisites are present: (1) a first jeopardy attached prior to the second; (2) the first jeopardy has been validly terminated; and (3) a second jeopardy is for the same offense as in the first. A first jeopardy attaches only (a) after a valid indictment; (b) before a competent court; (c) after arraignment; (d) when a valid plea has been entered; and (e) when the accused has been acquitted or convicted, or the case dismissed or otherwise terminated without his express consent.
