Investigative strategy and interviewing

The purpose of this chapter is to examine the use and relevance of strategy in anti-cartel investigations. The chapter draws together established practices, research and legal issues relevant to investigative strategy and highlights the experiences of a number of International Competition Network (ICN) members. As with previous chapters, the relevance of some sections will, to some degree, be determined by the legal and policy environment that governs an agency’s enforcement practice. This chapter is intended to be a reference tool for agencies that enables them to evaluate their own approaches and benchmark their experiences against those of their counterparts around the world. The chapter is divided into two parts: 1. Establishing the investigation strategy: this part will bring into focus the full-scale investigation of a cartel and explore manners in which competition agencies define and conduct the strategy of the full-scale investigation. 2. Evaluation of the investigation strategy: this part will illustrate how an investigative strategy should be revised and modified as evidence of the alleged cartel is obtained.
