Definition of Corruption

While following the present agitation for Draft Lokpal Bill through the Print/
Electronic Media, I remember after conclusion and fallout of the Sawant- Commission, Mr. Suresh Jain saying that- It is high time that 'corruption' be defined ('Bhrashtacharachi Vyakhya Karanyachi Vel Aleli Aahe')!!!

Every Minister has to take an oath before taking up the charge which, amongst other things (e.g. to uphold the Constitution/secrecy) vows that the Minister shall perform duties without fear & favour, affection or illwill. I feel,When this Constitutional Oath is broken, corruption occurs.
However, the solemn oath-taking has been converted into a rhetoric/celebration and they forget their vow the moment they sign the register for having taken the and get down from the dias.
