If your work becomes harder because this outrageous Federal Court of Justice decided that even alleged terrorists have rights, then I'm truly terribly sorry for you. It is certainly extremely annoying when you have to present evidence and cannot simply withhold exonerating witnesses and otherwise base your case on unverifiable claims (because they're kept under wraps) when you want to throw someone in prison for 15 years. It is certainly a real cheek that in the future you'll have to think about how to incorporate information from intelligence services—the same intelligence services that have been wrong at every turn and have sometimes simply fabricated evidence—into proceedings.
I have a good suggestion for you: why not simply use only information that can also be presented in court. And remember the principle of benefit of the doubt for the accused. Then things will go better in the next instance...
