“Mr Clark also emphasised the fact that the Code applies to land of all kinds. There may be sensitive Government buildings, for example where it would be inappropriate to allow access for an MSV, let alone the actual installation of electronic communications apparatus simply on a basis of a good arguable case, 7 without requiring the operator ultimately to satisfy the full test under paragraph 21. … We consider that most if not all of the potential problems can be dealt with by the terms of the agreement that the Upper Tribunal imposes. It could for example provide for limited hours of access, restrict access to sensitive parts of the building, provide for supervised access and so on. ... In an extreme case, the Upper Tribunal might exercise the discretion which it has under paragraph 26 to refuse to impose the agreement at all.”
