OPBP’s reports have had significant impact in court cases and now it is also having an impact on academic scholarship. OBPB has been cited in Brian Farrell’s new book, Habeus Corpus in International Law. OPBP prepared a report on the use of secret evidence in October 2011, in order to assist the Joint Committee on Human Rights in its deliberations on the use of secret evidence in UK courts. We then produced a supplementary report on the topic in March 2012. These reports have been cited in Brian Farrell’s book, which was published by Cambridge University Press in 2017
