Where I live, judicial appointments are not made through the Parliament, the appointments are made by the government of the day by the Attorney-General. If the courts get overworked (as does happen from time to time) then that reflects badly on the A-G and the government of the day. The idea that opposition politicians could hold up judicial appointments in a Senate or upper house environment for dumbarse political reasons is hideous.

We have some judges who are relatively conservative and some who are relatively progressive but we don't have the lunacy we're seeing out of US courts (particularly SCOTUS) because there is a lot less politics in the judiciary here. We don't have governments stacking courts with the expectation that their bidding will be done.

Electing sherrifs, prosecutors and judges and sending judicial appointments through Senates does not seem to be working well for the US, I can't recall reading many articles which contradict that.
