In Ofcom's ruling on the `Great Global Warming Swindle' [1], they say
amongst other things that (pdf page 20 onwards) (paraphrased):

The view promulgated by parts 1-4 of the programme, that climate
change is not man-made, was settled as a falsehood by the time the
programme was made. In their view, because the question was settled,
it wasn't a matter of controversy.

This seems to lead to the absurd situation that an opinion which is
generally accepted as false is regarded by Ofcom as less
controversial, and more suitable for broadcasting in the form of an
allegedly factual polemic, as compared with an opinion on a subject
about which there are wide differences of opinion.

That is, it is more OK for C4 to broadcast something utterly wrong
than something doubtful.

Could this be a subject of a successful judicial review challenge ?
