A lot of ai research isn’t published in journals but either posted to a corporate website or put up on the arxiv. There are some ai journals, but the ai community doesn’t particularly value those journals (and threw a bit of a fit when they came out). This article is mostly marketing and doesn’t show anything that should surprise anyone familiar with how neural networks work generically in my opinion.

They have demonstrated they will overturn themselves based on how they are feeling that day, so I wouldn’t rely on getting the same judgement if a similar case comes up and they are pissed at the defendant.

Everyone likes to think that AI is objective, but it is not. It is biased by its training which includes a lot of human bias.
