Either ERHC still believes it has block 4 and is taking the matter to court or it's still negotiating a deal with Shell, assuming Shell won the bidding war.
But if ERHC believed we really lost block 4, then we'd have an 8k. They don't have to do an 8k because there's no real threat of stock certificate revocation now that the case is dismissed... but they have been doing 8k anyway because they care about their shareholders.
So no 8k is probably good news... but bad news for all the short sellers.
