The legal approach
Of course I think he's right that the BBC are in breach, but more precisely I think the concept of a Charter such as the BBC have (and updated just a couple of years ago) an absurdity, a political charade, a conceit played upon the conscience of the public. Moore grounds his case on the failure to remove Jonathan Ross from his post following RossyBrandSachsgate.
Fair enough, I would say, yet as Moore also points out, there are many reasons to wish not to pay the BBC for the use of your television.
John Kelly for example has been summoned to court to answer for his non-payment, and grounds his case on the BBC's lack of balance in coverage of the EU.
Obviously we should watch both cases carefully. I note that the BBC renewed their charter a couple of years ago. In the new Charter I believe there is no reference to impartiality, which was one of the Labour Government's friendly touches for the BBC; removing the impartiality clause really left sites like this one in a changed situation.
Therefore John Kelly may have a problem since the BBC's partiality is central to his complaint. Instead, the Charter
talks of the BBC's "public purposes", which are,
(a)sustaining citizenship and civil society;(b)promoting education and learning;(c)stimulating creativity and cultural excellence;(d)representing the UK, its nations, regions and communities; (e)bringing the UK to the world and the world to the UK; (plus the promotion of digital telly)Charles Moore is evidently basing his prospective case on the failure in "sustaining citizenship and civil society" exampled by the Ross-Brand-Sachs scandal.
