Unless the law's been changed, or the FIJA (Fully Informed Jury Association) has been putting out bad info, jury annulment is still legal.
All findings of fact in the American Judicial system are supposed to be findings of the Jury. The Jury finding can not be overturned.
What the Jury can not do is find someone guilty, but the law unconstitutional, so in that sense, the legal community is right, there is no juror annulment.
Jury Forman:
"The defendent is innocent, if he gives back the cows."
Judge:"This verdict is improper."
Jury Forman:
"The defendent is innocent, and he can keep the cows."
