“There is certainly not an intention to ignore instructions from the First-tier Tribunal, and operational instructions have always stated that these directions must be complied with fully, including in respect of providing DLA evidence to the Tribunal. The actions of the Department in this case and those referred to by Judge Durance clearly do not meet the standards required to allow the timely and correct progress of these appeal cases and those serious concerns have been passed onto the operational officers who manage these matters.”
