Lots of people seem to be celebrating Lord Justice Moses's judgement that the petitions of Corner House Research and the Campaign Against the Arms Trade merited a judicial review. On one had I think the issue of how the investigation was stopped by the Attorney General and how that office interacts with the law as a whole does merit scrutiny.
On the other hand lots of people think that this means we will at some point know the facts behind the case. I suspect them to be sorely mistaken. The odds of the current government or the MOD revealing the details of the Al Yamamah agreement which BAe (as was) say they were following to the letter is about the same as those you could get on the man who signed it being the next prime minister.
