The binding legal principles established are: (1) Section 126(1)(a) and (b) of the Insolvency Act provide disjunctive alternatives - a party may seek either written consent of the practitioner or leave of the court to sue a company under corporate rescue, but need not pursue both; (2) Applications for leave to sue under Section 126(1)(b) may be brought by way of urgent chamber application where urgency exists, as the provision is substantive and specifies jurisdiction rather than procedure; (3) Where parties to a contract have agreed to a dispute resolution mechanism (such as arbitration), the court will require them to exhaust that mechanism before granting leave to sue, in accordance with the principle of sanctity of contract (pacta sunt servanda); (4) Representatives of shelf companies who are recognized as such in contracts may have standing to represent the company in legal proceedings where the board has not been regularized, particularly to protect the company's constitutional right to a fair hearing under Section 69 of the Constitution; (5) The purpose of the moratorium in Section 126 is to provide breathing space for companies under corporate rescue, and courts should make orders that minimize disruption to the rescue plan and conserve the company's limited resources.
