We have special arrangements for dealing with a “high cost case” – potentially complex, voluminous or time-consuming criminal cases.
We have a procedure to identify, monitor and assist you in such cases. We can also identify and facilitate the employment of one expert (or junior counsel) in circumstances where there is generic evidence and no inherent conflict in interest between the clients.
There are identifiable triggers in a criminal case which point towards a case potentially being high cost or complex. These factors can be identified at a relatively early stage.
Each factor may be significant on its own, but more usually several such factors come together to indicate a potentially high cost case.
Such factors may include:
A typical high cost case would be likely to cost over £50,000.
The presence of any of these factors does not, in itself, indicate that the case will be high cost.
