It’s difficult to anticipate what the post-NRC situation will be. There are many factors involved. If the Supreme Court invalidates 1971 and accepts 1951 as the cut-off year for identifying illegal immigrants from Bangladesh, the whole process would boomerang. Let’s be realistic. Many immigrants declared as foreigners have disappeared—almost a lakh—and the police have failed to trace them. How will they be identified? Whose names will be deleted from the NRC? Is there any arrangement to track down these people?
