Hi dancer22
I would send off a Mandatory Consideration as this occurrence is highly unusual. A DWP officer has interviewed your son and concluded that he is lacking the mental capacity to administer his Benefits. How long ago was the Appointeeship made and has your son's health improved greatly since?
I would also phone the DWP and ask for a copy of the Assessor's report, the ESA85.
