Answer:
The constitution protects against double jeopardy
Step-by-step explanation:
Section 35(3)(m) of the Constitution provides the constitutional guarantee that:
[e]very accused person has a right to a fair trial, which includes the right not to be tried for an offence in respect of an act or omission for which that person has previously been either acquitted or convicted.
This entails that a person cannot be tried twice in a court or tribunal of competent jurisdiction on the same set of facts or conduct. If the person is charged with a crime which is essentially the same as a previous charge where the person has been acquitted of convicted, the person is entitled to raise the plea of double jeopardy.
