Police Powers of Criminal Investigation: Principle or Pragmatism

Abstract

This article will examine the divergence between law and practice in criminal investigation by police and consider the degree to which it may contribute to an imbalance between the interests of the individual and the public interest in the efficient detection and investigation of crime. It will be argued that the imprecision of the existing law and the failure by the legislature to accord new, tightly-defined, specific-purpose powers to the police have made a major contribution to the pressure on police to misuse existing (and often more intrusive) powers or to exercise de facto powers not authorised by law. It is contended that this pressure often arises from a desire by police to find a more practical means of attaining agreed community objectives than that provided by the artificial standards of the existing law. A strong case can therefore be advanced in favour of refurbishing police powers to accord (more closely) with present conditions, while at the same time strengthening the safeguards cast around those powers. This article will argue that case.
