Yet, what the opinion offers is not a new edifice but a sturdier legal architecture. By advancing an “all of the above” approach to international law’s sources; by treating these sources as interlocking parts of a living legal system; and by recognizing erga omnes and erga omnes partes duties with concrete consequences for responsibility, the Court has given States, courts and litigants a legally rigorous, source‑sensitive map.
