The problem with judges having terms is that judges are supposed to be above politics. They are supposed to interpret the law according to the constitution, without politics getting involved. If they had terms, then obviously politics would play a role in their decisions.
The problem now is that sadly, judges forgot that fact. They try to impose their own views on things all the time, instead of just following the constitution. What we really need is a way to take action against a judge who does not do what they’re supposed to.
