Can a jury go against a judge's direction?Watch
In cases where there is a jury, I thought the judge would just help them establish facts and legal principles. A framework for them to make a decision in, the decision itself is theirs and theirs alone.
First of all guilty and not guilty are different processes.
A judge can not direct a guilty verdict.
A judge may find that as a matter of law the charge has failed (for a number of reasons.). The judge strictly speaking has no personal power then so he simply directs the jury to find the defendant not guilty on that charge.
If in his summing up the judge strongly hints to the jury that they should find him guilty (judges are very skilled at doing this without being too obvious) the jury can simply ignore him if they think injustice will result regardless of the evidence. A not guilty verdict by a jury can not be over turned on appeal. Ponting is the classic case. (a whistle blower).
