You want a corrupt judiciary - elect them.
The legal system we have is not perfect, but it's pretty good.
Electing your legal representation is not a great way to run a system. In Australia we run cases to get the right outcome, not to be popular. Leave the glorified popularity contests to the pollies and leave running the judiciary to those eminently qualified and suited to the roles.
The Australian legal fraternity is not above the law, but they are separated from the state, and that's necessary, otherwise we have people trying to be popular forcing cases that shouldn't be taken. - Not all cases should be taken, and that is why sometimes a case will be nolle prosequi, others are 'dropped'.
An elected judiciary is an accountable judiciary. Any corruption from that is a corruption of the electoral process. An elected judiciary is accountable in that repeated unjust rulings and judicial negligence can be punished by loss of position. What is the consequences now to a judge found making unjust rulings? A successful appeal, may "fix" the screw up, but what is the consequence to the judge? Nothing. What does it take for an incompetent judge to be sacked? The Gov't can't as far as I know. Maybe only the legal fraternity itself can, but their first instinct is to protect their own.
Of course those involved in our present legal system would claim it is perfectly fine - perfectly natural to defend their corrupt and unaccountable self-interest!
Who defines the "right outcomes"? The legal fraternity of course! If the "right outcomes" are not popular, are they "right"? Well I suppose the legal fraternity arrogantly assume they know better than anyone else, so in their view they are and stuff everyone else, especially the victims of crime!
How can a legal system that takes an invariably hard line on financial crime (substantial jail in many cases) yet a sickeningly soft touch on violent crime (suspended sentences, minimal jail terms) be considered anything other than complicent as virtual accessories in many of the criminal outrages in the country?
