"1. The Registrar failed to undertake appropriate balancing of the prejudice to the respective parties flowing from his decision.
2. The Registrar failed to give sufficient weight to the fact that the plaintiffs had changed solicitors and that the previous solicitors had made no significant progress on the provision of discovery.
3. The Registrar took into account what he considered the merits of the plaintiffs' claims, an irrelevant consideration in the making of a case management direction.
4. Alternatively to ground 4 above, the Registrar placed too much weight on what he considered the merits of the plaintiffs' claims.
5. The Registrar imposed further onerous conditions upon the plaintiffs in excess of those normally required in discovery but failed to provide additional time to allow the plaintiffs to comply with those obligations.
6. The Registrar in Order 2 reversed the normal onus of proof in requiring the plaintiffs to demonstrate that their discovery is adequate.
7. Order 4 was pre-emptive and without grounds.
8. The Registrar failed to state or alternatively failed to state sufficiently the reasons for exercising his discretion as he did."
