Happily. Depends on whether your original PIP award involved you asking for mobility on the basis of overwhelming psychological distress. Anyone whose case was refused on that basis will be reviewed but it will be over a period of years and the detail is not clear. Right now, as you have no PIP, you would be as well to ask for a late mandatory reconsideration (you're well within the 13 months maximum) on the basis of the illegality of the law change and see what happens from there. At worst it gives you a new decision to appeal. At best it gets some or all of your award back and possibly arrears.
A new claim would not necessarily be any more successful.
