To follow on to eric's comment, there are two major aspects of the law:
- what is written as law
- how courts rule
The most important aspect is "how courts rule". This is because law is open to interpretation by those ruling on it.
The main upside of using judges instead of juries is that precedent is real. In a jury trial, you are relying on a random group of people to choose the outcome. In a trial ruled by a judge, you can reasonably expect that judge to rule in a similar fashion as they have on similar cases or based on precedent of previous cases.
Having a more predictable outcome that eliminates the "wild card" aspect of juries allows your representation to give you better legal advice as they can study how the courts have ruled in the past and give advice that will likely put you on the correct side of the law.
