If the Senator is reasonable, she will understand my response. That is the advice I received. Common sense dictated that I would have been on extremely doubtful ground if I had tried to apply it retrospectively. If I had, it would undoubtedly have been challenged. I do not know how long that process would have taken, but even if I had been successful, these permissions would still have had to go through the entire planning process again. Every individual agreement would have had to be referred back to the local authority to secure agreement on how the 20% requirement was to be achieved. I would have lost the supply in the immediate future, certainly for the next year or two.
