The email about the tribunal didn't say we couldn't mention it (or I wouldn't have done), but it didn't say any more than the two leaders of SEEN were co-respondents to a claim against Defra, for discrimination. It says the claim says that the words on the SEEN website were an act of discrimination (I think). It did ask us not to worry and recognised that people may do.
The email with the letter attached which came a few days before was very clear that it could not be shared outside the CS. But I've managed to recruit three new members on the back of it!
Re the tribunal, they don't get into the public domain really until closer to the date. The press probably won't be interested for quite a while yet. So you're unlikely to see anything online unless SEEN release something, which I suppose they may do on the back of the summary of the letter being published, I assume they liaised and it wasn't a leak!
