3. It is settled law that cause of action consists of bundle of facts which give cause to enforce the legal injury for redress in a court of law. The cause of action means, therefore, every fact, which if traversed, it would be necessary for the plaintiff to prove in order to support his right to a judgment of the court. In other words, it is a bundle of facts, which taken with the law applicable to them, gives the plaintiff a right to claim relief against the defendant. It must include some act done by the defendant since in the absence of such an act no cause of action would possibly accrue or would arise . In view of the admitted position that contract was executed in Bombay, i.e., within the jurisdiction of the High Court of Bombay, performance of the contract was also to be done within the jurisdiction of the Bombay High Court; merely because bank guarantee was executed at Delhi and transmitted for performance to Bombay, it does not constitute a cause of action to give rise to the respondent to lay the suit on the original side of the Delhi High Court. The contention that the Division Bench was right in its finding and that since the bank guarantee was executed and liability was enforced from the bank at Delhi, the Court got jurisdiction, cannot be sustained.
