As representatives of the State, prosecutors have special responsibilities that the defense does not have. Prosecutors are supposed to be on the side of justice, so they should look at the evidence with that goal in mind. If they find evidence that would tend to show that the defendant is innocent, they have a responsibility to share that evidence. Specifically, a Supreme Court case called Brady requires that the prosecution must turn over any evidence to the defense that meets certain criteria. If they do not do this, a conviction may be reversed. There are a number of different ways that a skilled Tampa criminal defense attorney may be able to get your conviction overturned. Of course, individual results will depend on the facts of your case.
There are certain requirements that need to be met in order for a court to find that a Brady violation has occurred. The burden is on the defendant to show that a Brady violation has taken place. The first thing the defense needs to prove is that the evidence either impeached the testimony of a prosecution witness or was exculpatory. They also need to prove that the State either willfully or inadvertently withheld that evidence from the defense. Finally, the defendant needs to show that the evidence was material and that their lack of access to the evidence hurt their case.
