Answer:
Double Jeopardy
Step-by-step explanation:
If new video evidence is found after Jeff's initial trial that shows he did in fact commit the act of shoplifting, he could be brought to trial again for the same act. This is known as double jeopardy. In the United States, the Fifth Amendment to the Constitution protects against double jeopardy, but it applies only to criminal trials and not to civil trials. So, Jeff can be brought to trial again for the same act in a civil trial.
