I agree with Prh. You need to get it right out of your head that the LA are unreasonable. Unreasonable in the legal sense means 'so perverse that no ordinary person could have made this decision in light of the facts' or thereabouts. An example would be allocating a school to a child whose parent is a police officer, when the school in question has a parent who has threatened to harm the officer. Or a social worker who works in the area served by the school, etc. It isn't 'they're unreasonable because siblings should be able to go together'.
You're going to need to have done some homework because your arguments seem, so far, to be: 1.'he needs to be with his brother' and 2.'this is a good school'.
- Will fail because:
- there are thousands of siblings who are separated.
-You moved out of catchment so caused the separation.
-if they were at a infant/junior school they'd be separated anyway.
-many parents have to drop to two locations.
- Will fail because:
-the panel can't make a judgement on 'how good' a school is -what would that say to parents at the school in question?
So your appeal has to be focused on why this school is necessary for your DS.
You can't rely on the usual 'needs a local peer group' because you're seeking to take him away from the local peer group. So you'll need to look at what provisions this school has that are different or 'other' from other schools. You'll have to demonstrate that these are important for your child (e.g. a nurture group for a very shy child, or an extra-curricular provision that is particularly key for the child).
I have to say that I think you'd struggle to do that, given that your child is 4 years old.
You could say that you can't provide after school play because you have to travel to the older child's school, but the logical response would be to move the older child closer to home.
Be prepared for a question about whether there is a school with places for both children, if you go down the line of separation being a bad thing.
