So it seems like people weren’t having to register at all before and now only unmarried couples will, confounded by an existing belief that Muslim men “coerce” Hindu women to marry them, which is conveniently listed as a denial reason.
The government where I live knows where I live, whom I live with, and recently fined me ~20€ for telling them I moved in later than I should have. That’s understandably stifling to some, but not everyone and it’s not a universally unacceptable infringement on human rights, as long as it is equally imposed. Doing it only to unmarried couples or intentionally to break up interfaith relationships is a different thing.
