Page "The League of Extraordinary Gentlemen" Paragraph 23

When no such apology was forthcoming, Moore ( and O ' Neill ) decided to withdraw future volumes of the League from DC in protest.

Since the duo were still working on The Black Dossier at the time, it was agreed that it would become the last League project published by DC / WildStorm, with subsequent projects published jointly by Top Shelf Productions and Knockabout Comics in the US and UK respectively.
