The correct example of double jeopardy is:
being sued for causing Jack Smith’s death after being found not guilty of Jack Smith’s death.
Double jeopardy refers to the legal principle that a person cannot be tried twice for the same offense once they have been acquitted. In this case, being sued after being found not guilty pertains to civil liability rather than criminal prosecution, hence presenting a situation that exemplifies the principle in a broader sense of legal consequences.
However, if the options were strictly talking about criminal proceedings, the nearest would be:
being tried for murder of Jack Smith after being found not guilty for murdering Jack Smith.
This explicitly indicates being tried twice for the same crime.
