I'm so sorry to hear this, ineed 
No, scratch that, I'm fucking livid.
The panel feel more evidence is needed because your DD is in a new school. I don't know whether this decision is valid or not. I suspect it's not valid at all. I suspect it just reflects a degree of willing credulousness and useful idiocy. But what the fuck do I know?
But I'm pretty sure of one thing - the panel could have quite easily made this decision to adjourn in the run-up to the hearing. Sparing you and your family at least some of the stress you've been under over the last few days. Possibly even giving you a Christmas that you could actually enjoy. And, I'm guessing, saving you a fuck-tonne of money too, as you'd only have to pay for witnesses once.
I've met a few panel members. I've met some that know their shit, in a narrow, quasi-theological, quote-the-SENCoP-verses sense. But I've never met -one not one - that understands the pressures and strains that parents withstand when they go to Tribunal.
When parents take on publicly-funded employees on their home turf. When parents with no time or energy to spare step miles out of their comfort zone to secure the most basic rights for their children. When parents face attacks on their competence, motives or character from people who are nominally paid to ensure their kids get the education they are entitled to.
In short, I've never met a panel member who gets what this is about for us. What we invest, and what we have to lose when we go through this. And this much I know - I've never met one who would last five fucking minutes in our shoes.
Imagine what these people would do if it was their elderly mother's care in question here. Imagine them listening to the pious intonations that more evidence is needed. That the under-resourced care organisation just need a bit more time to absolutely prove that they can't do the job. Imagine them hearing that no-one can't be sure whether the number of piss-infused cold sores on their mother's body has grown or not. That their mum's cry for help is just what all women of a certain age do, she - and the whole family - just needs to show more resilience for now. That as she hasn't reached rock-fucking-bottom yet, we'll give it a bit longer to prove it beyond reasonable doubt.
I wonder what they'd do.
