Ben Franklin thought that judges should be elected. He thought that the voting public would select the best person for the job. See page 455, Benjamin Franklin, An American Life by Walter Isaacson.
Judges are appointed in Canada. In the U.S.A. federal court judges are appointed. Some U.S.A. states elect judges. Many years ago a Denver lawyer told me that Colorado lawyers prefer to elect judges because it tends to make the judges accountable and responsible. In Canada supreme court judges are appointed until age 75. Some appointed judges act irresponsibly. For example, when I was practicing law in New Brunswick in the 1970s I acted for the plaintiff in a trial before a Queen’s Bench judge on a real property matter and the judge took five years to render a decision.
In the U.S.A. some elected judges receive campaign donations during elections from persons who later appear before the judge as an accused or as a party. The appearance of a conflict is apparent.
A retired Canadian judge told me that the problem of a Canadian judge being irresponsible is probably lessened by the recent improvements in the selection process. All appointments of federal judges and provincial supreme court judges in Canada are made by the Federal Cabinet. The quality of such appointments has since Confederation been generally very good. Since 1867 very few judges in Canada have been removed for misconduct.
The Canadian appointment process has resulted in a high degree of judicial independence. Independent judges tend to protect individual and democratic rights and the rule of law.
