Understanding Supreme Court Observations:

  • The Supreme Court referred to microcontrollers in EVMs as “agnostic”, stating they do not recognize political parties or candidates, only the buttons pressed by voters.
  • Justice Sanjiv Khanna emphasised that the buttons on ballot units are interchangeable, programmed at the manufacturer stage without knowledge of which party will be assigned which button.
  • The case addressed concerns about EVM transparency and vulnerability to rigging, with the court emphasising the non-disclosure of EVM source code to prevent misuse and protect integrity.
