At UVA many years ago, one of my roommates was one of the unfortunate 20 or so annually expelled -- the only outcome of being convicted of breaking the "no cheating, stealing, or lying" honor code. It didn't take repeat offenses, expulsion was a first offense consequence.

Interestingly, it seems like you weren't joking about the decline:

> Finally in the spring of 2022, a sanction reform referendum succeeded with more than 80% of the vote, changing the penalty for an Honor violation from expulsion to a two semester suspension. [1]
