The Arthashastra, in Topic 6, describes checks and continuous measurement, in secret, of the integrity and lack of integrity of all ministers and high officials in the kingdom. Those officials who lack integrity must be arrested. Those who are unrighteous, should not work in civil and criminal courts. Those who lack integrity in financial matters or fall for the lure of money must not be in revenue collection or treasury, states the text, and those who lack integrity in sexual relationships must not be appointed to "Vihara" services (pleasure grounds). The highest level ministers must have been tested and have successfully demonstrated integrity in all situations and all types of allurements.
