Appeal. If you are out of time, start again.
Mandatory Reconsideration without adding anything extra in the way of evidence is unlikely to be successful (it is for some) but Tribunal is very fair and impartial.
You need to be careful filling out the forms, there are plenty guides online which show you how to get your description of someone's needs across in a way that's very clear and meets the DWP's criteria. Sometimes just that can make the difference between having an award or not.
Because of that, some agencies are so overloaded with people needing help that they cannot help until it's a Tribunal. Similarly, many HCPs are now not writing letters of support because they are unlikely to have seen the claimant in many of the situations mentioned in the forms. e.g. the preparing a meal question, none of our HCPs could comment on that because they've never seen how their patient copes or not in that situation.
@dottodot, All the following questions are rhetorical, please don't answer here, but have a think to see if you could present his case in a better way, then either appeal or start again. I'm guessing he had a face to face and that he gave some responses to the assessor? In DWP's eyes, that means he's already seen the assessor who would be a stranger, so they will have absolutely ignored and dismissed all your evidence about him not being able to approach and communicate with a stranger.
Are you down on the forms as his advocate, or did you complete them as if he'd done it himself? Did he speak to DWP on the phone and could he understand and answer appropriately? That makes a big difference to DWP when it comes to demonstrating his inability to communicate, to them he'd have demonstrated he has no problems but the reality is more likely to be you being in the background prompting, or having prepared for days just so he could say his name and address.
Please do think about appealing, Tribunal Panels are impartial. Could you prep him to sit in front of three people (four if DWP turn up) so they can see how uncomfortable he is and how he struggles to communicate? There are large tables in between the panel and the claimant/advocate, so they are not close to you at all and they are not intimidating.
It isn't easy but it's not impossible.
