Is there a date published for the result of DH's Tribunal?
I don't think there will be a published date for the result. The decision will be ready when the Tribunal has determined its verdict. I'm not familiar with the exact processes of the ET, but if other Tribunals are anything to go by, a draft decision will be given to both parties for a review (for factual accuracy, commercially sensitive information etc).
If, as expected, the decision does not go DH's way, then if history is anything to go by, lies and half-truths will circulate as to why.
