Section 610 — Criminal Code: Circumstances of aggravation

Where an indictment charges substantially the same offence as that charged in an indictment on which an accused was previously convicted or acquitted, but adds a statement of intention or circumstances of aggravation tending, if proved, to increase the punishment, the previous conviction or acquittal bars the subsequent indictment. A conviction or an acquittal on an indictment for murder bars a subsequent indictment for the same homicide charging it as manslaughter or infanticide, and a conviction or acquittal on an indictment for manslaughter or infanticide bars a subsequent indictment for the same homicide charging it as murder. A conviction or an acquittal on an indictment for first degree murder bars a subsequent indictment for the same homicide charging it as second degree murder, and a conviction or acquittal on an indictment for second degree murder bars a subsequent indictment for the same homicide charging it as first degree murder. A conviction or an acquittal on an indictment for infanticide bars a subsequent indictment for the same homicide charging it as manslaughter, and a conviction or acquittal on an indictment for manslaughter bars a subsequent indictment for the same homicide charging it as infanticide.
