need help reclaiming disabled tax credits

In the past year or so, the courts found that hmrc had to allow people who had previously denied reclaiming disabled tax credits which had been wrongly calculated by hmrc, we fall into this category and require as much information as possible on the court case strangely the information on this court case online seems to have vanished does anybody on here know anything about it or able to point me in the right direction ????????? just to add the tax credit folks are being really bad about this and wont tell us whether were due any tax back,
thanks T
