I fully expected Meghan would win her appeal. The first instance judge was no slouch and he’d delivered a clearly explained and reasoned judgement. That doesn’t mean ANL were wrong to appeal – that’s a basic right of any litigant. But I similarly wasn’t surprised by the Court of Appeal upholding the first instance decision.
I even liked some of the tone of Meghan’s statement (though it’s a bit premature seeing as ANL have one more tier of Appeal, but she’s clearly had this drafted for a while and was itching to send it out 
). But some of it grated.
Making comments like tabloids setting up a model that “rewards chaos over truth” and twisting facts and manipulating the public sits extraordinarily ill on someone who herself has done exactly that. Not just in misleading he Court about her involvement in Finding Freedom either. As @Pawprintpaper and @WeeTattieBogle say, her supporters gloss over the fact that both the parties and the judge at first instance all agreed that the People Article inaccurately recorded the letter and the Duchess's purpose in sending it.
It was not a heartfelt attempt to repair the father-daughter relationship and was never an olive branch as the People Article alleged. Its main purposes were to reprimand Mr Markle for his previous conduct, and to try to dissuade him from talking to the press in future. It was written to “tug on the heartstrings” and manipulate the reader, as she herself made clear, and she then used it as a weapon to discredit her father (and don’t @ me with comments that her five friends briefed People about it without her knowledge – I expect that’s something else that she conveniently forget to be accurate about) and then swooped in with a lawsuit to position herself as the victim when he defended himself.
Even the Court of Appeal accepted that it might have been proportionate to disclose and publish a small part of the letter to rebut inaccuracies in the People Article, but ANL went too far (they also went all in with stories about the story they created from his rebuttal, but they is what they do…). And they will have to pay her for the risk they took and getting it wrong, but Meghan has had her reputation thoroughly damaged in the process too.
Oh, and I am amused by all those painting Jason Knauf as a smearer here. Meghan was presumably talking about people like him when she wrote her statement - "This is a victory not just for me, but for anyone who has ever felt scared to stand up for what's right”. Just like oooh, Jason Knauf, who had first hand knowledge of the matters in the court case and was brave enough to stand up and let the court know that the Duchess was misleading them in her evidence and statements of case, which she then had to admit. He’s the one here who’s actually been brave, and who actually had something to lose by being truthful.
