Abstract
This work, which corresponds to the doctoral thesis prepared by Prof. Ricardo Molina López, Doctor of the University of Seville (Spain), is undoubtedly a remarkable academic effort of foundation and theoretical development on the purposes of the criminal process. It is not easy to find books like this one that, before developing the institutions of Criminal Procedural Law, are concerned with the constitutional foundations of the process and its necessary relationship with substantive Criminal Law; therein lies one of the greatest incentives for the reader to undertake its reading.
