rejecting overqualified applicants?

<p>the reason i asked is because I know someone who had 2400 sat1 3x800 sat 2 4.0 gpa all 5’s in AP, got into princeton but rejected from cornell
also I seen some ppl here on CC who got accepted to MIT but rejected from cornell
so I was just seeing if there is an know case of cornell practicing strategic admissions but i guess its inconclusive</p>
