Guidance can be found in the Federal Court’s decision in Cubic Electronics Sdn Bhd (in liquidation) v Mars Telecommunications Sdn Bhd [2019] 2 CLJ 723, where Richard Malanjum (CJ (Sabah & Sarawak) as he then was”) held inter alia as follows: “[70] We turn now to the issue on burden of proof. The initial onus lies on the party seeking to enforce a clause under s. 75 of the Act to adduce evidence that firstly, there was a breach of contract and that secondly, the contract contains a clause specifying a sum to be paid upon breach. Once these two elements have been established, the innocent party is entitled to receive a sum not exceeding the amount stipulated in the contract irrespective of whether actual damage or loss is proven, subject always to the defaulting party proving the unreasonableness of the damages clause including the sum stated therein, if any. [71] If there is a dispute as to what constitutes reasonable compensation, the burden of proof falls on the defaulting party to show that the damages clause is unreasonable or to demonstrate from available evidence and under such circumstances what comprises reasonable compensation caused by the breach of contract. Failing to discharge that burden, or in the absence of cogent evidence suggesting exorbitance or unconscionability of the agreed damages clause, the parties who have equality of opportunity for S/N 19vRbMidFUKWwd8bhlTiuw understanding and insisting upon their rights must be taken to have freely, deliberately and mutually consented to the contractual clause seeking to pre-allocate damages and hence the compensation stipulated in the contract ought to be upheld. [72] It bears repeating that the court should be slow to refuse to give effect to a damages clause for contracts which are the result of thorough negotiations made at arm's length between parties who have been properly advised. … [73] At any rate, to insist that the innocent party bears the burden of proof to show that an impugned clause is not excessive would undermine the purpose of having a damages clause in a contract, which is to promote business efficacy and minimise litigation between the parties (see: Scottish Law Commission, Discussion Paper on Penalty Clauses (Discussion Paper No 103), December 1997, paras. [5.30]-[5.40]). [74] In summary and for convenience, the principles that may be distilled from hereinabove are these:
