Away from the Numbers: Opinion in the Court of Appeal
The Court of Appeal has recently addressed opinion evidence in numerous cases. Recurring themes have been addressed consistently with the exception of R v T (2010). It is suggested that the rationale in T is not as persuasive as that adopted in other cases. This article advocates that, where appropriate, a Bayesian approach should be adopted. In favouring a Bayesian approach it is suggested that ambiguous phrases such as ‘scientific method’ may not serve courts effectively and judges have been correct, in the majority of cases, to approach opinion evidence in a pragmatic, case-specific fashion. The Court of Appeal warrants credit for emphasising the importance of pre-trial hearings and robust case management.
