OK. When it comes to court on 19th December, HMRC can withdraw the petition.
However, now that the petition has been published in the Gazette, any other creditor can now piggyback onto it. So, if has been suggested by some on here, there are other businesses which have not been paid by the club, they could take the petition on, seeking to get their debts paid. This, along with the fact that bank accounts get frozen, is one of the main reasons it was particularly stupid to allow the situation to reach this point.
I'll also add that the above is from the best of my understanding - I am in no way an expert on these matters!
