- Some general definitions of grand corruption agree on i) misuse or abuse of high-level power; ii) large scale and/or large sums of money, (iii) harmful consequences. These elements from general definitions have been useful when differentiating grand corruption from other forms of corruption, such as petty corruption.
- Recently, efforts have been made to establish a legal definition of grand corruption. For instance, Transparency International has worked on a draft legal definition, which was released in 2016 and revised in 2019.
- The main rationale behind efforts for a legal definition is to develop a criminal offence of grand corruption, as a first step towards the empowerment of national and international authorities with better legal tools to pursue corrupt high-level officials and to end impunity.
