If a case is reviewed, but there is already someone convicted of the crime, what happens?

Question

I know someone who has been convicted of something, manslaughter, and the case is being reviewed sometime soon, why would it be reviewed?? Isn't it over with?
What could happen if it is reviewed?

Answer 1

1.) He could be being reviewed by the corrections board,
for a reduced sentence or early release.

2.) He, through his lawyer, may have appealed his case to a higher court, and they agreed to review it. This could be because of new evidence, or something that happened to
thwart his trail during the first hearing.
If this is the case, he might be allowed a new hearing or
the new hearing could be denied.

Answer 2

It could be any number of things. It depends on who is doing the review. Is it an appelate court? A parole board?

An appelate court would review any new exculpatory evidence that might reverse the conviction.

A parole board would review the behavior of the person convicted and make a determination as to whether or not to grant parole.

Answer 3

You sound worried. This is done if there has been new evidence that was found to be left out of the trial. If enough evidence is found to show this person innocent by any reason of doubt, the decision will be reversed. The person would be released.

Answer 4

well, there are often grounds for appeal in a case...
sometimes new evidence comes up and must be looked at, sometimes there is a question as to the effectiveness of counsel, or even court procedure.
