Your question, as stated, isn't a neutral request for information – it should be. By insisting on statutes defining "justice", you've especially made it impossible to answer the question, since justice is never statutorily defined. There is a domain of law, jurisprudence, which addresses such questions; and there is, outside of the domain of law (and in the domain of philosophy), a wide range of theories of what constitutes justice. There is some intersection of these two currents.
There are probably legal studies (i.e. articles in law reviews) which address the concept "justice" from a more legal perspective, in particular looking at case law and characterizing what facts lead justices to find a decision to be "just" versus "unjust". A request for the leading legal literature on that topic would be reasonable, and if framed as an objective question about the nature of law, might not get so heavily downvoted and closed.
