The article doesn't touch on snooping "privileged" conversations, like attorney/client, which are typically considered legally sacrosanct, but GCHQ is known to have listened to. How are UK attornies (forgive me, I don't know the correct term) taking that? How are the judges taking it? Does this "secretly introduced" legislation make that legal as well?

At what point does "secretly introduced" legislation become anything other than tyranny? I would think very rapidly, but what do I know?
