When a class of shares is revoked, brokers are forbidden from trading it, and FINRA deletes the symbol. End of story, usually, but not here. I pinged SEC and FINRA on this years ago, but all I got was form letters saying that everything was done according the 'rules'. My conclusion?: Administrative foul-up at FINRA combined with another at SEC...because, while the final order happened, it was not posted to their litigation list here: http://www.sec.gov/litigation/admin/adminarchive/adminarc2009.shtml ....which is apparently what FINRA keys off of.
Only the initial decision is there. Normally, final decisions are also posted there, obviously.
