(2) In sub-paragraph (1), “exceptional circumstances” mean that the expert's evidence is key to the client's case and either—
(a)the complexity of the material is such that an expert with a high level of seniority is required; or
(b)the material is of such a specialised and unusual nature that only very few experts are available to provide the necessary evidence.
