Skip chronicles them at Initium. My favorite on Skip's list: The Three Tenors' case. The market definition: Three Tenors' albums. The crime: reducing discounts on the Three Tenors albums. The injured consumer class: people who think it is a God-given constitutional right to pay less than $20 for old recordings of Three Tenors albums. Oh, the Humanity!
Then again, case #1 is the real outrage.
