What happened to the ESC A19 Flowchart?

Around a year ago I was looking in the HMRC manual (the rule book used by Inspectors to inspect) and I came across a flowchart for ESC A19. Very interesting, I thought. A lot has happened in HMRC land over the last 12 months and today the flow chart has been taken away now and replaced with “(This text has been withheld because of exemptions in the Freedom of Information Act 2000)” The question is: why remove the flowchart? It seems harmless enough. And what justification is there to remove it? Any answers please coment below or use the contact page. Oh here is the flowchart, so you can see just how dangerous it is!
