The judges ruled that the lockout will continue until the full hearing.
The issue is clearly political in that two of the judges ruled that the lockout remains and they admonished the judge who initially ordered the lockout lifted. Meanwhile the 3rd judge wrote a lengthy dissent where he defended the judge. Any guesses about their respective political affiliations? Your guess would be correct. Amazing how this goes.
Now on the surface I'll go along with the decision: lifting the lockout might harm the NFL and at this point the players are essentially not losing anything. Now that's different when it comes time for camp, but for now it seems reasonable.
