The word Lokpal has been derived from the Sanskrit words "loka" (people) and "pala" (protector/caretaker). So the word Lokpal means 'protector of people'. The concept of Lokpal has been drawn up to root out corruption at all levels.The basic idea of the Lokpal is borrowed from the office of the ombudsman in other countries.
It provides for filing complaints of corruption and anyone (except for a public servant)can file a complaint and the Lokpal has to complete the inquiry within 6 months.
