68. 在资产非法增加罪(《联合国反腐败公约》第二十条)、在没收程序中要求罪犯证明所指称的犯罪所得或其他应予没收的财产的合法来源的可能性(第三十一条第 8 款)以及不经过刑事定罪而没收财产(第五十四条第 1 款(c)项)方面可能会出现挑战，在没有足够的程序保障的情况下，可能与“法无明文不为过失”的原则、无罪推定、免于自证其罪的权利和财产权相冲突。在这方面，毒品和犯罪问题办公室强调，有必要保留资源，将其归还合法所有者或赔偿受害者，同时通过适当管理资产确保无辜嫌疑人能够按照恢复原状原则重新获得其资产。
68. Challenges may arise with regard to the offence of illicit enrichment (article20 of the United Nations Convention against Corruption), as well as the possibility, in confiscation proceedings, of requiring that an offender demonstrate the lawful origin of alleged proceeds of crime or other property liable for confiscation (art. 31 (8)), as well as non-conviction-based asset forfeiture (art. 54 (1) (c)), which may be in conflict, without sufficient procedural safeguards, with the principle of nulla poena sine culpa, the presumption of innocence, the right against self-incrimination and the right to property. UNODC highlights in this regard the necessity of preserving resources for restoring them to the rightful owners or to compensate victims, while ensuring, through the adequate management of assets, that innocent suspects can regain access to their assets in line with the principle of restitutio ad integrum.
