The Upper Tribunal heard the judicial review, which was combined with an Attorney General's reference, over five days in May 2011 and reserved judgment until October 2011. The lengthy ruling upheld ISC's main ground of complaint, which was that the guidance did not reflect the true state of charity law on public benefit and charities which charge fees. A subsequent hearing and ruling in December 2011 ordered that the Commission withdraw large parts of its guidance or face a quashing order. The disputed guidance was withdrawn shortly before Christmas 2011, and replacement guidance was put out to consultation in 2012.
