A criminal conviction may carry severe consequences where the conviction is largely based upon evidence which subsequently proves to be unreliable. The realisation that a material witness, expert testimony, confessions, or forensic findings may no longer be regarded as reliable may give rise to significant concerns regarding the continued security of the conviction. It is at such times that criminal appeal solicitors may evaluate the possibility of mounting an appeal against the conviction.
When Can Unreliable Evidence Lead to an Appeal?
An appeal is not merely the chance to argue against the judgment again. The court will determine whether there is a legitimate legal reason to dispute the conviction.
The evidence can be made doubtful for various reasons. The witness could give an entirely different version of what happened, something new can prove them to be untrustworthy, or some scientific evidence can be proved to be invalid. A further option would be that certain information which was unknown before might cast doubt on the evidence.
What Happens If New Evidence Surfaces?
- Evaluation of the original evidence
The first step would be to investigate the trial evidence carefully. It could involve witness statements, expert witness testimony, interview evidence, documents, and many others presented in court by the prosecution.
Another thing to look into is whether there is any difference in knowledge after the trial. The reason for this is that new evidence can be very important in an appeals case.
- Challenging evidence that no longer appears reliable
A new opinion from an expert might sometimes point out shortcomings in the scientific or medical evidence provided. In addition, evidence obtained following conviction can also have a bearing on the validity of a witness’s testimony.
The Criminal Cases Review Commission has handled cases where there were unreliable confessions, new forensics, and evidence that had implications for the credibility of the prosecution’s witnesses. Where appropriate, it may refer a conviction to the appeal courts.
Why Timing and Evidence Matter
One must not assume that any piece of information will automatically result in a conviction being overturned. One has to consider how strong the evidence is and its relevance to the original case and how it may affect the outcome.
For instance, when dealing with criminal appeal cases that have been based on unproven or false evidence, the attorneys would have to prove exactly how the controversial evidence affected the prosecution case. If the evidence played a major role in the conviction, then the evidence against it will definitely be much more important than any other information.
Conclusion
When one finds out that the evidence used to obtain a conviction is unreliable, it can raise many concerns; however, it does not always guarantee the success of the appeal. One needs to take into consideration the type of new information and its potential impact on the existing case and the original verdict. Criminal appeal lawyers can determine the feasibility of challenging a conviction based on these considerations.
