DWP and select committees

There is an argument that recent select committees and over sight committees provide very clear statements of the current situation regarding all benefits and contract. In most cases the evidence is damning
I question why this evidence cannot be more effectively used by claiments within the appeals process or in the legal processes.
This would possibly lead to reviews that would make improvements to a system.
I have spend some time taking the key points out of these committee meetings . Think about the implications
If Practitioners are damning and statements indicate the issues then there are grounds for the use of the statements
