"The suit alleges that Iyer told other workers the employee was Dalit and had gained entry into the prestigious Indian Institute of Technology through affirmative action." Indian law explicitly requires a much lower standard of admission for the lower castes. Is it illegal to take consideration of this fact?
I'm going to assume the person in question graduated from IIT as well as gained entry. If so, I don't see how it matters if he got in through a door with a lower bar, if he graduated, he graduated. Unless graduating from IIT is a rubber stamp for showing up?
Also, just because the bar is lower for admissions doesn't mean that people who cleared the bar couldn't have cleared the bar otherwise. I don't see how IIT entrance exam scores are relevant for employment at Cisco anyway.
