If they say no you have no right of appeal.
Yes you do, see GRA Section 8
GIRES say: The GRP is definitely minded to grant applications, wherever legally possible, which is why directions are given rather than making final decisions which might not be in favour of the applicant. So despite the high rate of requests for further information very few applications actually fail outright.
About 90% of applications are successful. It would be interesting to know what grounds someone could have to appeal. Either they have the evidence or they don't.
Anyway, the GRA needs updating.
Why? LGBT+ Lib Dems say themselves it was necessary to enable people to get married prior to the same sex marriage bill. There is no barrier to marriage now so it's pretty much obsolete. Less than 5000 people have a GRC because it's simply not necessary. The only other legal differences it makes are for AWS and prisons.
2 different laws. Got it?
Yes, and they interact. In fact, Labour (Lib Dems too?) are breaking the law by allowing self-ID tw on AWS.
Nobody is updating the Equality Act. Which means NO CHANGES TO STUFF LIKE SINGLE SEX SERVICES.
Maria Miller wants to. Labour want to. Don't know if the lib dems have said, but they probably want to. Governments only last a few years. Trans lobby groups are providing training that gives the impression to orgs that the EA has already been updated. They are blatantly making up the protected characteristics and telling orgs they MUST include any self-ID trans person in single sex spaces. ManFriday is going sterling work highlighting how this is playing out on the ground. Best dismiss them as 'silly' 
They are protesting about changes which literally nobody in government has proposed or hinted at
Here in black and white - see paras 17 - 22.
The best we can work out is that the people doing the protests seem to think that the Gender Recognition Act has some provision that changes how the Equality Act sees you. But it doesn’t. It really, really doesn’t. They made that up.
It does for the specific exception that permits AWS but labour have decided to break the law. Prison placement is not entirely governed by the EA but by prison service instructions. A GRC makes a very big difference to prison placements. If you have one you bypass the 'case by case' process of the Transgender Case Board.
In particular, they seem to think that “sex” and “gender” are different and defined things in law. Only they’re not. To the extent they are used in law, they’re largely interchangeable. But this is why you see them say stuff like “legal SEX protection for FEMALES”.
From the consultation on the Gender Representation on Public Boards (Scotland) Bill - The EHRC said that ‘sex’ and ‘gender’ are not synonymous terms, and that ‘gender’ is not a protected characteristic.
We say we need legal sex based protection because we are disadvantaged and oppressed because of our sex, not our 'gender'.
Both groups also get hung up on birth certificates.
Because the single sex exceptions are unuseable if someone has a new birth cert via a GRC and chooses not to reveal they are trans (even if it's bleeding obvious). This is irrelevant for toilets etc, but makes a big difference for things like genuine occupational requirements (rape counsellor etc.)
THE EQUALITY ACT ALREADY WORKS ON THE BASIS OF SELF ID.
Except for AWS but see above.
It’s been law for the last 8 years.
What has changed in the last 8 years is that trans orgs are 'training' everyone to think that the exemptions can't be used or that rhey don't exist. The other thing that's changed is the huge increase in the number of people IDing as trans.
We speculate that this is because transphobes are a bit thick.
I speculate that LGBT+ Lib Dems are misogynistic arseholes. Not much speculation required really, we have eyes and some of us can even read.
All over birth certificates. Because that’s the only proposed change.
AND STILL, NOT A SINGLE REASONABLE ARGUMENT HAS BEEN PUT FORWARD FOR WHY THIS REFORM IS NECESSARY
Here's a suggestion, let's just leave the law as it is and take the time to review how it's all working in practice for women.
