It strikes me that the complaint against judicial elections (as voiced on this listserv) is rooted in the absence of life tenure — not elections per se. You could have elections filling judicial vacancies — but with the candidates’ receiving life tenure. And you could have appointments by political authorities to fixed and limited judicial terms — with the possibility of reappointment. The threat to the rule of law (such as it is), lies with the prospective candidate for reelection/reappointment to judicial office biasing his/her decision for self-interested reasons. But that conflict of interest will appear whenever you have terms of limited duration with the possibility of reelection/reappointment. It is not elections per se that create the conflict.
This is an excellent point.
