Judges would be assisted by neutral expert witnesses and guided by evidence-based practice guidelines. Unlike juries, they would issue written opinions that establish precedents and standards of care, removing much of the uncertainty physicians now practice under.
One of the weird things about philosophical Conservatives: opposition to Judge-made law. There are understandable reasons for why Conservatives have seen the Supreme Court as the enemy of the Constitution (though I tend to think the Courts are forced to fill in the blanks left with the transition for state to national sovereignty). But thinking that yearly legislatures are preferable to Courts just doesn’t seem all that consistent to me.
