There's overwhleming irony in this petition, in that it achieves exactly what the Government wanted from an external contract - complete deflection of blame. ATOS may be a vile, money grabbing corporation (or simply a well focussed business, depending on your perspective) but ALL the responsibility for the how the Welfare System operates lays with the Department of Work and Pensions and the relevant Ministerial oversight. Everything that ATOS has done has either been prescribed by Government or permitted by Government - having Offices up flights of stairs with no lift so people couldn't get to medical exams and were then penalised by removal of benefit - the Government permitted ATOS to have those offices, and it was DWP operatives that implemented the penalties.
ATOS has never made decisions about awards of benefits, the resposonsibility for those is with the appointed DWP decision makers, - they of course are happy to blame ATOS for 'the wrong kind of reports' - but the ATOS reports are exactly what the Government contracted for. The Law is quite clear it is for the decision maker to weigh all the facts and to decide what material is necessary to consider. Should the DWP be investigated for harm brought to numerous vulnerable people ? I'd say yes, but that harm is an inevitable effect of Government policy. Putting ATOS in the frame is emotionally appealing, but it's a deflection from where the real blame lies and that's with Government, and ultimatly with that part of the population that supports 'welfare reform' (a big percentage of UK voters). Blaming ATOS will leave many people's conciences clear - and free to vote to hammer the poor some more come the next election.
