Recently (2010–2011) new criminal legislation to combat illegal income and corruption was passed and publicly discussed in Lithuania. Within the list of the new legal measures, special attention should be paid to criminalisation of illicit enrichment, establishment of a model of extended property confiscation, reinforcement of responsibility for corruption-related offenses, a provision that not only property but also personal benefits may constitute a bribe. It can be seen from the explanatory letters attached to the draft laws and the political debate (...) that the new regulation is expected to achieve decisive breakthrough in the fight against corruption and illegal income. However, without any doubt as to the necessity to fight against those social evils, the author presents critical evaluation of the reform by applying the test of principles of criminal law, legal language and practical effectiveness. By making critical conclusions that the new criminal legislation deliberately lightens the prosecution’s goal of incrimination and the burden of proof, the author warns about the purposive instrumental nature of the new laws, which are balancing on the threshold of legitimacy. In the article the author reveals crucial shortcomings of the new legislation: in some aspects it lacks legal certainty, in other aspects it ignores the principles of guilt, presumption of innocence and proportionality as well as the conception of criminal law as a last resort (ultima ratio). As a result, the new legal means against illegal income and corruption leave space for applying inadequate repression beyond their intended purpose, in addition, they criminalise human conduct that is insufficiently dangerous and create preconditions for senseless criminal prosecutions and violation of human rights.
