Open ballot voting for elections to the Rajya Sabha and voting through proxy for voters in the armed and paramilitary forces were introduced by amending the act in 2003. A provision for enrolling overseas Indian citizens in electoral rolls was made in the most recent amendment in 2011. Introducing a provision empowering the Commission to use electronic voting machines, conferring disciplinary jurisdiction over officers (including police officers appointed for conducting elections) to the Commission—these reforms have all strengthened the EC and streamlined its functioning.
