ICANN dosn't have any rights to .xxx as it is already being served by the alt-root networks. Contrary to ICANN's propaganda, ICANN isn't the only Domain Name System serving the Internet community. The alt-roots not only resolve all the Legacy TLD's & ccTLD's (.com .org .net .edu .us .uk .zh etc..), but also all the alt-TLD's (.pub .oss .xxx .unix .biz etc...).
Untill ICANN aquires the Right's to .xxx from the lawful owners of it, they would be infringing on the owners rights.
That's why they are stalling. They can't just start selling domain names on the .xxx TLD with out the premission of the current alt-TLD owners consent.
