ORO NEGRO DRILLING PTE. LTD. & 5 Ors v INTEGRADORA DE SERVICIOS PETROLEROS ORO NEGRO, S.A.P.I. DE C.V. & 6 Ors

In long-running litigation between Oro Negro group companies and their former directors, the third defendant applied for an unless order to compel the plaintiffs to provide sufficient answers to interrogatories about legal fees paid to Mexican and US lawyers. The court granted the unless order, finding the plaintiffs had failed to comply with the earlier interrogatory order and that their justifications for non-compliance were impermissible collateral attacks on the outcome of the earlier proceeding.
