Single economic unit and waiver of pre-emption rights governed the disputed share sale structure.

A wholly owned subsidiary used as the vehicle for a parent company's investment may, on the facts, be treated with the parent as a single economic unit, so the subsidiary's contractual obligations can bind the holding company. The pre-emption clause in the shareholders' agreement was treated as a qualified right of first refusal, not an absolute restraint on the proposed sale structure, and it did not require sale on terms chosen by the pre-emptor. Waiver was inferred where the applicant, with full knowledge of its rights, participated in the bidding process and acted inconsistently with the asserted pre-emptive right, so interim relief was refused.

Issues: (i) whether the holding company and its wholly owned subsidiary could be treated as a single economic unit so that the subsidiary's contractual obligations concerning transfer of shares in the joint venture would bind the holding company; (ii) whether the pre-emption clause in the shareholders' agreement barred the proposed sale structure adopted by the holding company; (iii) whether the applicant had waived its right of first refusal by participating in the bidding process with knowledge of its contractual rights.

Issue (i): whether the holding company and its wholly owned subsidiary could be treated as a single economic unit so that the subsidiary's contractual obligations concerning transfer of shares in the joint venture would bind the holding company.

Analysis: The subsidiary was wholly owned and controlled by the holding company, and the materials showed that the holding company itself projected ownership and sale of the power assets as a group transaction. The business arrangement and sale proposal indicated that the subsidiary functioned as a vehicle for the holding company's investment in India. In such circumstances, the separate corporate form could be disregarded to identify the economic reality of the transaction.

Conclusion: The holding company and the subsidiary were held to constitute a single economic unit, and the subsidiary's obligations under the shareholders' agreement and articles of association were binding on the holding company.

Issue (ii): whether the pre-emption clause in the shareholders' agreement barred the proposed sale structure adopted by the holding company.

Analysis: The right of first refusal conferred by the agreement was a qualified contractual right, not an absolute restraint on alienation. The clause permitted the shareholder proposing transfer to obtain third-party offers and then place the same opportunity before the other shareholder. The court held that the clause did not compel a transfer at a price chosen by the pre-emptor, nor did it prevent the shareholder from seeking the best available market price through a third-party sale process.

Conclusion: The pre-emption clause did not confer an absolute right on the applicant to insist on purchase of the shares on its own terms.

Issue (iii): whether the applicant had waived its right of first refusal by participating in the bidding process with knowledge of its contractual rights.

Analysis: The applicant had knowledge of the sale process, the assets offered, and its own contractual pre-emptive right. It nevertheless submitted a letter of intent and participated in the process, expressly acknowledging that the process would avoid delay from the first refusal mechanism. Waiver may be inferred from conduct when a party, with full knowledge of its rights, intentionally elects to proceed inconsistently with them.

Conclusion: The applicant was found to have waived its pre-emptive right.

Final Conclusion: Relief under the interim measure was refused because the applicant's asserted right of first refusal could not defeat the proposed transaction in the circumstances, and the application failed on the ground of waiver.

Ratio Decidendi: A wholly owned subsidiary used as the vehicle for a parent company's investment may, on the facts, be treated with the parent as a single economic unit, and a contractual pre-emptive right can be waived by a party's informed participation in the very sale process said to infringe it.
