Abstract
The essay offers an analytical exam of the meaning of the terms ʻpreparationʼ and ʻexecutionʼ contained in the general discipline of the ‘conspiracy’ and, in particular, in the crime of sexual violence. It also tries to overcome the incoherence that could arise from an incorrect interpretation of the ‘conspiracy’ in the article 609-octies of the Italian Criminal Code, which would be in contrast with the principles of reasonableness and conservation of acts, as well as with the principle of abstract speciality among legal rules.
