It has been deeply rooted in society as a 'convention', 'tradition', 'psychological need' and 'necessity' with a regular practice not only in public service, but also in business transaction and other kinds of dealings as well. All strata of the society have been adversely affected by corruption. Corruption is also the issue of governance and effective management. Corruption control is the most urgent and imperative task to be accomplished in Nepal to establish a fair and transparent governance system.
The Commission for the Investigation of Abuse of Authority (CIAA), is an apex constitutional body to curb corruption and its tentacles in the country.
