New Delhi, Dec. 12 -- The Supreme Court on Thursday observed that the idea of verifying citizenship may not be alien to the notification for holding special intensive revision (SIR) as the term migration - one of the grounds cited by the Election Commission of India (ECI) for revising rolls - may also include cross-border migration. Hearing arguments in an ongoing proceeding where the SIR in Bihar has been challenged in a bunch of petitions accusing the ECI of disenfranchising citizens on mere suspicion of citizenship, a bench of Chief Justice of India Surya Kant and justice Joymalya Bagchi said, "Migration can be trans-country. It may not be within the country alone." The court was responding to senior advocate Raju Ramachandran, appearing for one of the petitioners, who said that if the ECI was required to determine citizenship, it should have stated so clearly in its June 24 order declaring SIR for Bihar. The only two grounds suggested were "rapid urbanisation" and "frequent migration of population from one place to another". The bench replied, "The idea of citizenship you claim is alien to the SIR notification but migration may not have an inbuilt domestic import. There is migration across borders in all economic gradients. It can be livelihood that drives people to cross foreign shores." At the same time, the court clarified that these are not its "conclusions" but to evoke the best arguments from lawyers for a better appreciation of issue....
