The 2003 UN Convention against Corruption stipulates that if the spending and living standards of public servants are not consistent with their salaries, then explanations should be required. Furthermore, if a sudden increase in an official's assets is clearly the result of illegal activity, but there is a lack of evidence because those that gave bribes are unwilling to speak up, legal proceedings can still be initiated.
2003 年聯合國訂定「反貪腐公約」，規定公職人員的消費水平和生活方式若不能與其薪資收入對等，就應要求解釋；甚至當明知其非法財產暴增，卻因行賄者噤聲、苦無確鑿證據時，仍可依此提出告訴。
