Hence my comment earlier that if you have something which works, which has a proven track record and an exceptional safety record you are on very dangerous ground fundamentally changing the parameters particularly when you have no safety case for doing so and, more importantly, not a single study whcih demonstrates the new proposals are better than those they replace.
In any other arena you would be wide open to some very substantial civil claims.
If anything comes of the EIR I shall be very interested to see the RIAs and how the changes are railroaded through unless UK IMCr holders are offered a very attractive carrot.
