Although it makes the NFU appear (rightly) to be stupid as fekk, it might undermine the narrative by showing that stupid people can get something right eventually. Could be argued that the science has "improved" and so the narrative is not soundly based.
There are good people on here who, if I understand things correctly, have been instrumental in the NFU changing its position on methane.
They now need to take this court case as an opportunity for the NFU to firmly, and very publicly, put the case that livestock are part of the solution not part of the problem. You can't be a little bit pregnant.
