oO) Because these clubs are all responsible enough to pay their taxes.
Portsmouth have basically avoided paying taxes on bonuses etc. (If HMRC are right, and they must have some pretty good evidence to take it to court.) And therefore do not deserve their place in the Football League and so they should be liquidated.
It's bigger than that mate.
When English club Portsmouth goes to court on Tuesday to fight the image rights battle against Her Majesty’s Revenue and Customs, it will have wide spread support from other clubs involved in football, rugby and cricket. This is because the case is going to have an impact on any club that includes image rights payments as part of the pay package of any sportsperson.
HM Revenue and Customs has claimed that Portsmouth owes GBP 18.2 million in "unpaid taxes of the image rights of certain players". This is an issue over which several other clubs are also in dispute with HMRC. The tax agency is aware that this case can serve as a legal precedent for many in the sports industry and feel hopeful that they can make a strong case that Portsmouth has been avoiding tax payments.
HMRC will make its case based on an alleged contract between the club and Sol Campbell which entitled him to GBP 1.67 million in image rights payments annually. At the time of the contract, one in every five pounds the club made was going to pay Campbell because Portsmouth’s earnings from merchandising and sponsorship activities at that time was only GBP 7.2 million a year. HMRC’s claim of GBP 18.2 million in unpaid taxes implies that Portsmouth had image rights commitments of around GBP 45.5 million and this seems like an extraordinarily high amount.
While Portsmouth will have the support of other clubs, they may well wish that they had a stronger case to back in the large-scale battle against the HMRC.
