"6. General 6.1 The parties shall procure that their respective parent, subsidiary and associated companies controlled by them shall be bound by this Agreement as if they themselves were parties to it. 6.2 In the event that either party sells or transfers its business or any part of it which includes the publications affected by the provisions of this Agreement, or any such substantial assets, it shall draw this agreement to the attention of the purchaser or transferee."
"First, there must be interference in the execution of the contract. The interference is not confined to the procurement of a breach of contract. It extends to a case where a third person prevents or hinders one party from performing his contract, even though it be not a breach. Second, the interference must be deliberate. The person must know of the contract or, at any rate, turn a blind eye to it and intend to interfere with it: see Emerald Construction Co. v Lowthian[1966] 1 WLR 691 . Third, the interference must be direct. Indirect interference will not do."
"There could be no clearer case than the present of an interference, namely, by Impact Holdings and Impact Motor as soon as they had control and were in a position to interfere, which procured not merely a prevention or hindrance to Kingswood in the performance of their obligations, but procured a direct breach by Kingswood of their contractual obligations. The interference was plainly deliberate and plainly direct." "
"Thus there is not a single case in which the De Mattos principle has been used to impose on a purchaser a positive duty to perform the covenants of his predecessor. It cannot therefore save the claim to performance of the covenants by [the fifth defendant] and [the sixth defendant] from being struck out. The negative injunction granted in De Mattos and the Strathcona case is of no use to the plaintiff. [The fifth defendant] and [the sixth defendant] are not proposing to do any particular acts inconsistent with the covenants given by [the original transferee]. They are proposing in fact to do nothing whatever. Under the De Mattos principle, this cannot give rise to any liability."
"...under the terms of the Tomlin order the only jurisdiction which [the judge] had in this action was to make an order for the purpose of carrying into effect the terms of compromise. An award of damages is not carrying the terms into effect. It is granting a remedy for breach of contract. In my view any claim by [the plaintiff] for breach of contract must be pursued in a separate action."
