It's a description of the legal system as a whole. It does not pursue justice, it merely seeks to enforce the laws as written. And I think it's pretty clear that our laws do not seek justice. For, how can locking up a man - a man who has not yet reached his 20th birthday - for years on end in a concrete box for the "crime" of consuming a plant be just?
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.
