Has anyone successfully challenged IAS?

Even though I have been successful at tribunal and got my PIP reinstated, I am still pursuing IAS for answers as to how the trainee assessors report could have/should have been relied on when making the original refusal. Indeed, the errors carried on right through two DM's and two IAS clinical experts. They refer to a condition I do not have, and never have had. Their responses to my questions fall far short of what a professional service provider should provide. So, it's off to the Independent Case Examiner. Does anyone have any experience they could share of going through this process?

Morning. I have been pursuing a DWP complaint with ICE for over two years now!!
I did get a letter from ICE last year saying that they have asked the DWP to REVIEW DLA & PIP claims prior to 2016...Yay!!! ..... but to expect delays because of Covid.....
Still waiting for DWP response..
They will say ‘no’ at every turn... Just be a major pain in the A***

That helps,thanks. DWP has already made me a conciliatory payment on account of another error they made in their dealings with me, so even if ICE comes good, I still doubt anything will come of it. I have also reported the trainee assessor to the HCPC and they are investigating his online social media presence. I'm sure some folk think I should just let it go,but the treatment I have experienced and witnessed is appalling, so I intend to pursue.

Hi Gary, yes I did see this, good for her. I am taking the case to the HCPC and they are investigating, but the County Court option sounds good.

Hi Margo and anyone else who needs to go to court. I came across this organisation
www.supportthroughcourt.org
and found their legal volunteers on the phone extremely helpful and knowledgeable, and it is free!
best wishes, Denby
