@Blossomtoes has this one right. I watched some of the press coverage unfold at the time, and this adhered to the absolutely strict conditions which, if journalists break, can land them with contempt charges. When someone is charged with a crime the newspapers can say what they are charged with, and that's all. They can then say nothing until the case comes to trial, and at that stage they are allowed to report only what the jury hears in court. No speculation as to innocence or guilt is permitted. The coverage followed due process.
As for the post you're responding to, this has Mark McDonald bang to rights. He's a maverick; a chancer. (As, incidentally, is David Davis). He's known for it. He takes on high-publicity, low-stakes cases, (for him; what does he have to lose?) and creates as perfect a media storm around them as he can. The intent was always the CCRC - the appeals process is all-but exhausted and you can read the reasons for the two rejections in the judgements posted online. They are very clear. There's a strict set of criteria for all appeals applying to every individual - no one is singling Letby out for unique or prejudiced treatment. Her case simply didn't meet those criteria. And at that point, no legal irregularities were found with Goss's handling of the case. It's really that straightforward.
McDonald is a KC. He knows the law. And the law in this country isn't conducted by media, nor is it within the remit of press conferences. Yesterday's proceedings change nothing about due legal process or the handling of the Letby case. It's a complex case, with a huge body of evidence involving numerous areas of specialist expertise that are difficult enough to unpick on their own, let alone by lay people. And the nature of academic research (I know, I conduct it) is that for most theories there will be oppositional views and contestation. Very rarely if ever is there one received body of accepted, received knowledge which challenge, further research and broader investigation can't move on to the next notch. It's the job of the court to unpick that. If this is in question, then the 'press conference' has just burned its boats in answering that, as Blossomtoes pointed out.
What hope for a fair retrial now, amid the tsuami of publicity surrounding this case (which happened after its conclusion, not before)? None. A retrial has to be off the table. I suspect the only options now are that she stands convicted or those convictions - all 14 of them - are quashed and she walks free. It would take something seismic for this to happen - McDonald and his band of experts, in turning this into a public spectacle and a PR trial, have made sure of that.
Letby is a woman with absolutely nothing more to lose. McDonald has capitalised on this. He is concerned with his own PR. Nothing else.
