I think there will be legal challenges to PIP cuts.
Simply because they are arbitrary: Reeves seems to have decided that mental health issues don't exist or that they don't cause people daily issues or that she can magically make people who are disabled not disabled....
Which is nonsense but also discriminatory (because it treats people with mental health issues and those with physical issues differently).
Only lawyers will be happy with this mess.
Reeves also forgets that people on PIP can appeal to an independent tribunal if they disagree with DWP decisions on their claim. So this is just going to cost the tax payers a fortune in appeals and will completely log the PIP assessment system which is already not coping with new and existing claims.
