In April this year, we commented on the first setback by the National Crime Agency (NCA) in their use of unexplained wealth orders (UWOs).

The NCA had obtained three UWOs against properties worth approximately £80m, but the orders were dismissed on a court application by the Respondents because, among other things, Mrs Justice Lang DBE found that some of the evidence relied upon by the NCA “was flawed by inadequate investigation into some obvious lines of enquiry” and that the agency “failed to carry out a fair-minded evaluation of the new information provided by the UBOs and Respondents”.

At the time, we noted the NCA’s stated intention to appeal this judgment. However, on Friday the Court of Appeal determined that the appeal had “no real prospect” of success and there was “no compelling reason” why it should be heard.

This is no doubt a significant blow to the NCA, which until the hearing in April had an unblemished record of success with UWOs. The opportunity to develop more crucial case law at the appeal stage has also been lost. However, the original decision carries many lessons for future applications for (and the upholding of) UWOs. The swift resolution of these UWOs may therefore present the NCA with an opportunity to focus resources on new targets. Whether this decision has more serious implications for the use of UWOs in general remains to be seen.
