He also urged the government to get the whistle blowers' protection bill and citizens grievance redress bill passed by parliament in its winter session.
Jaitley said no law was ideal and there was scope of improving it based on experience.
Earlier, Jaitley told reporters outside parliament that the BJP was "extremely keen" on passing the Lokpal bill.
The party gave a notice for suspension of the question hour to take up the Lokpal bill, he said.
On the Samajwadi Party opposing the legislation, Jaitley said one party cannot hold the whole system to ransom.
