Since it first entered the criminal legal practice, DNA has become an
indispensable tool in fighting crime, allowing both unambiguous
identification of the criminal by traces of biological material left
at the crime scene as well as acquitting innocent suspects.
Understanding how DNA evidence is obtained and evaluated allows the
defence to find pitfalls in the evidence and in data interpretation.
A match between the defendant and a biological sample recovered from
the crime scene does not and should not automatically mean
conviction, even if it is a complete match. DNA is a means of
identification and, as other means of identification, it is prone to
errors, uncertainties and conflicting interpretations.
At Medical Genomics we will guide you through DNA evidence in your
particular case, help you to understand how DNA evidence was
obtained, whether it can be interpreted in a way different form that
of the prosecution expert, explain what is the significance and the
probative value of the evidence and how it can be successfully
challenged in court in order to minimize its impact or even dismiss
it completely. We will also provide expert witness testimony in
court should this be required.
We have published extensively in
legal press on the use of DNA in legal practice including the book
"Dealing with DNA evidence: A Legal Guide" which is the first of
its kind which treats DNA evidence within the framework of English
Law.
