Writer James Robinson revealed that the title will avoid continuity snarls with the rebooted Justice League comic by being set in the vanished alternate reality, reports Comic Book Resources.
The Justice Society is a team formed of heroes who fought during World War II, which is at odds with the new DC Universe continuity, in which superheroes only appeared in the last five years.
"Everyone's saying, 'How can there be superheroes before the five years?' We're actually bringing back Earth-2." said Robinson during DC's New 52 panel at Fan Expo Canada.
"One of the problems with the Justice Society pre-[New] 52 is that so many of them were dead. There were very, very few of them alive, but you're going to see some people that haven't been around for a while fighting crime and being a part of the team again, so just bear with us."
DC previously said that the Justice Society concept was being given a "rest", after it became clear that the team would not receive its own title in the relaunch.
Earth-2 was an alternate world that existed in DC continuity in the '80s and before, and was the home to the Justice Society and older versions of characters including Superman and Batman.
It was combined with the more modern Earth-1 setting during Crisis on Infinite Earths.
