I think the point of a new claim is to submit new evidence that your condition has got worse and continues to do so. The DWP have to look at it as a new claim and although they will be aware of the failed one they cannot dismiss it on those grounds, they have to look at all the evidence and justify their decision(s). Did you use our guides the first time? You might like to look at all the updated advice on the form filling and evidence gathering in the members section for PIP. This could help you see where you might submit new evidence or more evidence of how your condition(s) affect your ability to undertake the activities.
