Indeed it is. The question is, what from this the BBC selects.
Recently, for example, there's been: DU's admission he "forgot" to disclose potentially key material, the claim that biological sex is nebulous, his belief in his right to examine a vulnerable woman who's requested a female doctor only - unless she's alert and brave enough enough to twig he's male and challenge him directly (whereupon he may perceive her as "aggressive" and "bigotted")...
We can't assume reporting of his evidence must, of necessity, be in his favour! The point of a tribunal is, surely, that your own evidence can expose the flaws in your position just as much as the other party's can.
Some (all?) of my examples above have been since the report linked above, but I'd be interested to know if the BBC has shared these details yet themselves - some other media sources have.
Certainly, the reporting I've read from the BBC thus far, as someone who's read all the abbreviated live transcripts bar today's (behind!) has seemed blatantly biased, to the point of wilful misrepresentation of information / actively withholding that is quite clearly in the public interest.
