All is not lost. Ask for a copy of your publication scheme. If you get blank looks then you may wish to remind the council that under Freedom of Information Legislation it is required to adopt a Publication Scheme. I'm getting a bit rusty on the detail but I think you will find that the council's budget is one of the documents listed and therefore a copy of it can be demanded as an FOI request. That said, it would be far less time consuming for all concerned if the council simply published it of its own volition.
