This thoroughly researched articile from Disability News Service (DNS) explains why there should be a police investigation into what's been going on at the DWP since 2010.
DWP - the case for the prosecution
Kester Disability Rights is assisting several claimants in circumstances where the DWP knows they could be harmed by what it is doing. The DNS article shows it cannot reasonably argue it is ignorant of the implications, especially when it refuses to modify its repeated reassessment regime. The DWP has even received coroners' reports in the past making it clear that action is needed to prevent further deaths, but instead appears to have "doubled down" with ever more unnecessary, and potentially harmful, decisions to reassess chronically sick and disabled people for ESA or Universal Credit, even though the legislation requires no repeated reassessment of chronically sick and disabled claimants at all.
Deliberating placing seriously ill and disabled people under the continuous pressure of reassessment when it is well known their circumstances have not improved, and knowing they also have serious issues coping with the process, is inexcusable. And now we know what the DNS has revealed it can only be seen as causing harm intentionally. These practices have been proved to be dangerous and so carrying on with them with that knowledge has to be in the most serious category of abuses of power by a government department.
