The wording issue was tried by me last week and failed I am sorry to say. I used two of those cases. I also understand from Mr Mustard that EH has now changed his mind?
Re served/delivered: the deemed date of receipt is Monday the 29th. If you wanted to take the risk and apply to the Tribunal on the very last day of 28 days beginning with that date (you can work it out when it is), and they serve a charge certificate, that would certainly prove prejudice.
I also used the served/delivered argument in the same case last week which the adjudicator did not address in the decision so I am seeking a review. In that case, the appellant did not receive the NOR until 3 days after the deemed date of service.
As usual, when "the usual suspects" employ technical arguments, it's in the lap of the gods these days.
As for examples of appeal, if you mean cases in support I am unsure at present. Also, adjudicators do not like being inundated with others' decisions unless one is very specific about what in the decision applies to your case.
I would have to check the representations against the NOR to see if there is any failure to consider. Some adjudicators, even if there is a clear failure to consider a technical argument, will still refuse an appeal on said issue if they do not agree with it. Cannot access them anymore.
Just giving balanced and pragmatic advice. As Incandescent says, now a no-brainer.
