The High Court rules today in a case which could be crucial to the survival of cash-strapped Portsmouth.
HM Revenue & Customs are seeking an order blocking a proposed Company Voluntary Agreement (CVA) put together by the club's administrators to help them out of administration.
Today's decision by Mr Justice Mann at the High Court in London is regarded as so important an appeal to the Court of Appeal is likely whoever wins.
HMRC argued at a two-day hearing this week the CVA was "unfair and seriously flawed" as it gave preference to football creditors, including players, who were able to claim up to 100% of monies owed them, while other creditors, including the Revenue, would receive much less.
Gregory Mitchell QC, appearing for HMRC, said: "One class scoops the pool and the rest are left out in the cold." HMRC also argued they are owed £13 million more than the £24 million value put on their claim.
The administrators disputed the accuracy of the taxman's figures and assessments.
The case is being fast-tracked through the courts before the start of the football season.
Pompey were docked nine points for becoming the first Premier League club to go into administration and were relegated to the Championship at the end of last season.
Richard Sheldon QC, appearing for the administrators, said other Premier League clubs "wanted Portsmouth to go to the wall and divide all the TV money among themselves" when their financial problems were revealed.
But Premier League chief Richard Scudamore persuaded them to give Pompey an early parachute payment to allow them to complete the season. If HMRC's application is successful it could lead to the club facing a further points penalty before the start of the season, increasing the threat of liquidation.
