I missed that, probably because it is conditional on the BMAA's response not being acceptable.
I can't help thinking that withdrawal of the consultation is not the answer. If it is conducted in good faith, which we have to assume it is, it could suit the LAA and BMAA to be presented with unworkable proposals that can be totally rejected with solid arguments.
It might even suit the GAU to have the proposals, which do not necessarily originate from them, rejected in a public consultation, rather than be seen to give too much ground in private consultations with the LAA and BMAA. After all, even some in the GA Partnership might perceive the A8-26 activities of LAA and BMAA as an unfair advantage, which will only increase with the introduction of the 600kg microlight category.
I should admit to having lived a long time in countries where this explanation would be entirely plausible.
