The Treasury Solicitor's Department was instructed in the following number of applications for judicial reviews in each of the last three years:
Specific data on how many such reviews were upheld in whole or in part in each such year are not maintained by the Treasury Solicitor's Department. The information requested can therefore be provided but only at disproportionate cost.
The Administrative Court Office does not retain the information sought in this question. However, it is able to produce information on cases in which a Government Department is shown as first defendant. Where a Government Department is named as a subsequent defendant this information could be obtained only at disproportionate cost. The figures the Administrative Court Office has for cases where a central Government Department was named as first defendant over the last three years are as follows:
With regard to the number of these cases where the application was upheld, in whole or in part, this information is not held and, again, could be obtained only at disproportionate cost. However, the Administrative Court Office's case management system can identify the number of cases each year where Government Departments were named as first defendant and where the judicial review was granted following a substantive hearing. These figures are as follows:
These figures should be treated with considerable caution, since they relate only to the outcome of substantive hearings (not to the outcome of applications at permission stage). A number of cases settle either when permission to apply for judicial review is granted or shortly before the matter is heard substantively.
