This book has attempted to answer the question: Is the legislation on money laundering sufficient? In order to respond to this problem, exhaustive research has been carried out on the current legislation in this area, in addition to analysing the scope of this legislation, compared with the principles of classic criminal law. On the other hand, an examination of the jurisprudence in this area has also been carried out, in order to study what the courts of justice have considered relevant when dealing with the different cases that arise in this particular area.
