Quick answer

Double jeopardy is a constitutional protection: no person shall be twice put in jeopardy of punishment for the same offense. It shields a person from being prosecuted or punished again for an offense for which they have already been placed in jeopardy and the case has been terminated. For double jeopardy to attach and bar a second prosecution, several requisites must concur: first, there must be a valid complaint or information; second, filed before a court of competent jurisdiction; third, to which the accused has entered a valid plea; and fourth, the accused was convicted or acquitted, or the case was dismissed or otherwise terminated without the accused's express consent. Once these are present, the first jeopardy has attached, and a second prosecution for the same offense, or for an attempt to commit it, or a frustration of it, or for any offense which necessarily includes or is necessarily included in the first offense, is barred. A key point is the fourth requisite: the termination must generally be without the accused's express consent; if the accused themselves moved for the dismissal (except on the grounds of insufficiency of evidence or denial of the right to speedy trial, which are treated as an acquittal), they generally cannot later invoke double jeopardy. An acquittal is final and generally not appealable by the prosecution, because appealing it would place the accused in double jeopardy; the prosecution's remedy against an acquittal is limited (a petition for certiorari only for grave abuse of discretion amounting to lack of jurisdiction, in exceptional cases). There are also situations where a second prosecution is not barred, such as when the graver offense developed due to a supervening fact (for example, the victim later dies), or when the first offense and the second are truly distinct. So double jeopardy bars a second prosecution for the same offense once jeopardy has attached through a valid plea and a termination without the accused's consent, subject to recognized exceptions.
