Ok, this is just permission to appeal. You do not get a copy of the original request.
That is before a Judge and does not involved the respondent. So its only permission.
Even if you had gone to the permission hearing, you are not allowed to speak because its the other side lone application.
The appeal has been listed for 4th January 2018. So now you should get Appellants Notice, skeleton argument etc.
Its quite normal you are not told about the permission hearing as technically its nothing to do with you.
So now you need to put together documents to say why the appeal should not be allowed.
But what has been done here is normal - nothing out of the ordinary.
Can I clarify anything for you about this today please?
If not, I would appreciate a 5 star rating for my answer. Thanks!
