Section 240: Consequences supervening or not known at previous trial

A defendant acquitted or convicted of an offence constituted by an act or omission causing consequences which together with that act or omission constitute a different offence from that for which he was acquitted or convicted, may afterwards be tried for the last-mentioned offence if the consequences had not happened or were not known to the court to have happened at the time when he was acquitted or convicted when the consequences create the offence of murder or manslaughter.
