Well, sorta. A committee of farmers sets the percentage that has to be turned over. That doesn't mean each farmer gets to decide what to turn over, they are at the whim of the committee. In essence, each specific farmer has little or no control over how much of the produce is taken away, and they get little or no compensation for it. That's just plain wrong, it's easy to see how even a usually very divided court agreed 8-1 on this case.
The one idiot, sotomayor, had this gem:
So basically, they can say "sure, you may sell your goods in the market, but only if you agree to give us some portion of your goods, without receiving any compensation". Nope, that's not taking anything, not at all.
Glad the rest of the court was not OK with that.
