Justice is the job of the people. We vote, directly or indirectly, on the laws as written. And in the case of jury nullification can bypass the law completely.
Representative democracy is, in my opinion, a significantly worse form of distilling the will of the people into applied justice.
If the task is deducing justice from the will of the people, I’d sooner pick a tiny random sampling of the population to make isolated decisions, than the votes of party-affiliated politicians on laws which cannot take into account individual circumstance.
