I received mine in writing 2 days later, wasn't long at all
I got mine on day, depends if the court are running on time.It does happen.
Perfectly normal not to have a decision on the day, it doesn't mean anything. They're usually fairly quick sending you the decision letter and some receive it in a couple of days.
At my appeal 2 weeks ago they asked if i wanted to wait outside for my decision or receive it by post , I said I wanted it done and finished today , it took 15 mins to call me back in and have the written decision there on the desk , one for me and one for my representative,
