On 17 January 2012, Delhi High Court in its ruling on Dr. Subramanian Swamy's Writ Petition (Writ Petition (Civil) No. 11879 of 2009) challenging the use of EVMs in the present form said that EVMs are not "tamper-proof".
Another similar writ petition filed by the Asom Gana Parishad is still pending before the Gauhati High Court [REF].
