There was this poor farmer that everyone knew. The poor farmer was liked by all. Though he was poor he would give his shirt off his back to anyone in need.
Then there was the rich old guy in town that no one liked. He owned half the town. He was known to take advantage of anybody’s vulnerabilities.
One day the old guy accused the poor farmer of stealing his prize pig. The town constable charged the poor farmer with theft.
At the end of the trial the jury went to deliberate. The jury wasn’t gone but 10 minutes. The judge asked for their verdict. The jury declared the poor farmer innocent if he just gives the pig back.
The judge was outraged and scolded the jury sending them back to deliberate as instructed.
The jury wasn’t gone for any longer than 5 minutes this time. The judge again asked for their verdict. This time the jury declared the poor farmer innocent and he can keep the pig.
That’s jury nullification.
