Lonrho plc v Fayed [1991]

House of Lords reaffirmed that in unlawful means
conspiracy, unlike conspiracy to injure, does not require a predominant purpose
to injure the plaintiff.
So it is no defence that the primary purpose of
conspirators was to further some legitimate interest of their own.
However an intention
to injure still required – Denning’s dictum in Lonrho v Shell (No2) [1982] approved.
