Despite the earlier Supreme Court ruling stating that Aadhaar must be purely voluntary, the Indian Institute of Science Bangalore is now demanding Aadhaar for new admissions.
I have blogged about it at https://systemreboot.net/post/iisc-makes-aadhaar-mandatory-for-admission
I and a few others intend to speak to the administration soon and resist this new development. Let's see how it goes. Will post when there is more news.
