1st tier tribunals

It seems no time at all since I was thanking you all for helping my daughter through the process of applying for PIP. She was finally awarded the enhanced rate with 16 points by the tribunal panel for 3 years till mid January 2017. In February this year, she was sent another PIP application form to reapply and since then has had 2 assessments, as one had to be abandoned due to her suffering a cataplexic fit and sleep attack. Since then she has received a decision letter awarding her 2 points. We have requested a mandatory reconsideration - and then expect to march onwards to another tribunal - but then I ask myself - WHAT POINT IS THERE IN HAVING A TRIBUNAL DECISION WHICH IS MERELY A 'SUGGESTION' AND NOT LEGALLY BINDING!!! The DWP can override the tribunal decisions seemingly at anytime they feel like it. This process could go on - and on - and on.........
What happened to the Magna Carta - where the common man has the right to justice????

I'm afraid that all PIP claims are being reassessed a full year before the award ends
