Answer: results in a second trial
Step-by-step explanation:
When there is a mistrial in a criminal case, it is usually up to the prosecution to decide what they will do. If they feel like they would be able to get a conviction in another trial, they would pursue a second trial. This is what usually happens.
If they however feel like a second trial would result in the same outcome as the first, they would probably leave the case as is in order not to waste tax payer money.
