The judgement in the current case has no bearing as it is under appeal. Technically the PPI still belongs to creditors as things stand, however it will depend on the amount as to whether your former IP thinks it worthwhile to get the paperwork out of archives, if, indeed, it has not already been destroyed.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
