Bundesverfassungsgericht
The judges have a 12-year term, but they must retire when reaching the age of 68. A judge must be at least 40 years old and must be a well-trained jurist. Three out of eight members of each Senate must have been a judge of a Federal Supreme Court. Of the other five members of each Senate, most judges have been a professor of law at a university, a public servant or a lawyer.
