A statement of case is the documents that lay out the argument and evidence that you will use in your appeal. This must be done regardless of which appeal route sought, be it written representation, hearing or inquiry. A statement of case helps to paint a picture of your appeal.
A statement of case form can be downloaded from the government’s website, which gives pointers for what a statement of case should (and should not) include from both the appellant and the LPA. This form can be used to give notice to the LPA that you intend to lodge an appeal.
