1. An arbitration clause only ousts the jurisdiction of the court where arbitration is the expressed or implied first choice dispute resolution mechanism chosen by the parties. Where the clause provides for other processes before arbitration (such as a period for negotiation or mediation), arbitration is not the exclusive forum and courts retain jurisdiction. 2. A party seeking to escape contractual obligations on grounds of mistake bears the onus of proving: (a) that a mistake occurred; (b) that the mistake was not due to his own fault, carelessness or failure to conduct necessary investigations; and (c) that the other party knew of the mistake, caused it, or as a reasonable person ought to have known of it. 3. An offeror cannot escape liability from a contract by establishing he made a wrong offer which was accepted, particularly where the mistake was due to his own carelessness or inattention. 4. Men of full age and competent understanding who enter into contracts freely and voluntarily must honor those contracts, and courts will not rewrite contracts or excuse performance merely because the contract has become onerous or inconvenient. 5. The maxim caveat subscriptor applies: parties are bound by contracts they sign and must bear the consequences of their own ineptitude in failing to conduct proper due diligence before contracting.
