The Supreme Court's ruling on Personal Independence Payment (PIP) benefits payments for those with mental health issues "should act as a serious wake-up call" for the Government, the shadow work and pensions secretary has said.

Labour's Margaret Greenwood called for the "scrapping" of the "cruel and discredited" PIP assessment framework and replacing it with one "which treats disabled people with the respect they deserve and provides them with the support that they need".

SNP work and employment spokesman Chris Stephens said the PIP assessments need to be "overhauled" as he asked an urgent question on the issue.

Responding, Work and Pensions Minister Justin Tomlinson said: "We welcome the court's judgment and are pleased it has accepted there is a difference between prompting and social support, and there must be a need for social support to be provided by someone that is trained or experienced in providing such support."

He said PIP is a better benefit for people with mental health problems than the "legacy" Disability Living Allowance, and added that the proportion of claimants who get the higher rate is "five times higher" than under the previous system.

Mr Stephens asked: "Do you accept it is clear now that PIP assessments need (to be) overhauled, and that once again we find a situation that the process discriminates those with psychological conditions?"

Mr Tomlinson said: "I do push back about the need for PIP to have a fundamental reform."

Ms Greenwood called on the Government to "look again at those cases where people have been turned down".

She said: "The assessment framework for PIP is not fit for purpose and has created a hostile environment for disabled people."

She added: "It was revealed recently that more than 60,000 appeals against a test for PIP ruled against the Government in 2018 - that's 72% of all tribunals. Clearly this is wholly unjust.

"The fact that such a high proportion of PIP assessments are overturned on appeal speaks volumes about the failings of this Government's record when it comes to providing support to disabled people. Ill and disabled people should not have to fight through the courts to receive the support that they should be entitled to."

Mr Tomlinson added: "We want to get it right. We want to make sure people are treated fairly and are fully supported."

He said the House will be updated "once we have had time to consider" the legal judgment, but assured MPs "we take this very, very seriously".

Independent chairman of the Work and Pensions Committee Frank Field asked how many more claimants would now be eligible for PIP who previously were not, and urged the Government to commit to looking at all those claimants who had had their PIP application turned down to see whether they are now eligible under the new rules.

Mr Tomlinson replied that the Government "will be looking back at cases".

Labour's Debbie Abrahams (Oldham East and Saddleworth) said: "To be dragged to the courts yet again in relation to PIP and its totally inadequate support that it provides to disabled people is again a shame on this Government.

"And, on top of that, 60 disabled people a month die after being refused PIP. To say that this is an OK support system for the most vulnerable group of people in this country is an absolute disgrace."

Independent Heidi Allen (South Cambridgeshire) said there are still "significant flaws" with the PIP and ESA assessment processes as she queried: "Why is it that we're extending the contracts to Atos and Capita for another two years when they're not meeting targets?"
