This paper considers the confusion that exists between opinion and non-opinion evidence concerning telecommunication data – and thus the boundary between expert and technical evidence. The difference between presentation, explanation and interpretation (for Technical, Investigative or Evaluative purposes) of data is outlined. The authors consider how the term “interpretation” may be used differently in connection with expert witnesses, witnesses giving technical evidence, and by the judiciary, suggesting that this may give rise to unrealistic expectations of a practitioner’s ability to reliably answer questions. Recommendations for core competencies are made for those giving telecommunications evidence to recognise when they are presenting opinion evidence and therefore (potentially inadvertently) acting as expert witnesses.
