I’m aware that it’s not at the same level as a ruling, but I was suggesting that it was more than just an opinion in the common sense of the term. This is why it’s important to know what words like “find” and “legal opinion” mean in this context. In what capacity was the legal opinion sought? Would it be recognised in court as part of a challenge to the legality of GCHQ activities? Would it prompt a review of the activities by the government? It’s nice that a senior lawyer feels that GCHQ actions are or should be illegal, but on a scale of internet comment to high court ruling, how significant is it?
