"You shall not follow the majority for evil"—Exodus 23:2.
It is forbidden for a judge in a capital case to follow the majority decisions if the majority is only one vote greater than the minority. I.e., if there's disagreement between the judges whether an individual is deserving of capital punishment, and the group of judges that wishes to convict is one vote more than the group that wishes to acquit—it is forbidden to execute the defendant.
