"Law Reform in the World" - presumably as opposed to other-worldly law reform?
"Law Reform in the World" would be better titled "Law reform".
It makes sense your correction and I do accept it: It is short and precise. Further, as we have "more stars in the universe than grains of sand in all beaches" of our Earth, chances are that Law - "the Science that allows life in society" - will be better served with a simple and short entry titled "Law reform".
(Law reform in Earth may prove to be a most limited title...)
