Here's a link to the court judgment: www.bailii.org/ew/cases/EWCOP/2014/11.html
It's a very sad case. The woman "has been known to social services for almost all of her life, the subject of a child protection plan as an infant as a result of concerns about her ill-treatment at the hands of her own parents." Add in to that her moderate learning difficulties and her (very recent) diagnosis of autism, it seems the odds were stacked against her since her birth.
There's no doubt that the support services have been doing their utmost for a very long time but, ultimately, it's a case of this young woman not being able to comprehend the risk of her death if she were to give birth as she wished.
