There is always more than one way to skin a cat.
There are over 800,000 licenses issued in the UK, 150,000 of them are Basc members, this organisation will only listen to its members and rightly so, but if there was enough of a push by members towards a Judicial Review then they would have to make representations..
If they did not then there is the opportunity for misrepresentation of its members and make a legal challenge accordingly via its own legal cover..
I think you would have a better chance with that than a JR against the Police.
Having been on the inside workings of BASC for 5 years it was always a challenge to try and get them to think outside the box, we had several schemes going that required just that and there were forever getting kicked into the long grass,we need a review we need a consultation etc, spent thousands on Consultants and it never went anywhere..So I think unless there is a challenge by the majority of members you are wasting your breath..
There is another solution, if there is enough momentum for this then why not set up your own organisation and take out legal cover to cover such a challenge..
As Caorach has mentioned if a Judicial Review is granted then be under no illusion of the consequences, the establisment will fight the dirtiest of fights you have ever seen,if you lose then there is cost implication if you win against the Police to recover costs you would have to show they were somewhat negligent or unreasonable, again another cost implication to prove such.
Now I am not trying to pour water on the fire, but in my opinion there are other easier routes..
