Typical example of petty officialdom abusing the granting of too much authority. Sack the incompetent knobber who made this decision.....their job is to check the tax-return and ensure the correct tax has been paid.
Either they did check it, knew it was wrong and wilfully and fraudulently denied a rebate to the "customer" (NO! you knobheads, they're the bloody source of your income! IE indirectly, your employers! you are supposedly CIVIL SERVANTS - many are neither civil nor servile, in it's loosest sense of being of service)
OR the taxpayer made a return which was fictional but believable and has been hoist with his own petard.
As LJ said, whilst his fundraising is laudable, it is not relevant to the issue under discussion, IE duplicitous, arrogantofficials abusing their position.
