Intelligence sources can't be divulged and they know that, otherwise no one would ever come forward. So it gets bounced up the court chain whilst the lawyers make themselves a reputation and a load of cash, until maybe its heard in closed session.

You may as well codify it in the law. Right now, we will just ensure that the case doesn't get heard. Twenty years ago, the press would have been prevented from reporting it and fifty years ago the american's would have had the guy killed. If secret justice means that cases can get heard then it's probably no bad thing.
An Afghan man who lost five relatives in a missile strike started proceedings against the Serious Organised Crime Agency (Soca) and the Ministry of Defence demanding to know details of the UK's participation "in the compilation, review and execution of the list and what form it takes".
Legal letters sent to Soca and the MoD state the involvement of UK officials in these decisions "may give rise to criminal offences and thus be unlawful". They say Britain's contribution raises several concerns, particularly in cases where international humanitarian laws protecting civilians and non-combatants may have been broken.
"We need to know whether the rule of law is being followed and that safeguards are in place to prevent what could be clear breaches of international law," said Rosa Curling from the solicitors Leigh Day & Co. "We have a family here that is desperate to know what happened, and to ensure this kind of thing never happens again."
Britain's role in supplying information to an American military "kill list" in Afghanistan is being subjected to legal challenge amid growing international concern over targeted strikes against suspected insurgents and drug traffickers.
I suppose concern from Afghanistan, Pakistan and Yemen does make it international.
Still this has got to be the first UK based firm of ambulance chasers to broaden their targetting to include UAVs:
