They decided that it failed the public interest test, as Janner was diagnosed with Alzheimer's disease in 2009 and the associated dementia had progressed to a point where he could not engage with the court process, and his evidence could not be relied upon. This meant that a court case could not proceed. Four specialist medical practitioners, two acting for the prosecution and police and two for the defence, had confirmed the severity of Janner's dementia. Just over a week later, it emerged that although the four doctors agreed Janner had severe dementia they were not unanimous on the six points listed in the CPS statement. Only one was asked if Janner could be faking the condition, a suggestion which was categorically dismissed.
