Plaintif menanggung beban pembuktian bahawa plainitf berhak menuntut sesuatu jumlah gantirugi tersebut dan hendaklah mengemukakan bukti-bukti yang menyokong tuntutannya. Di dalam kes Guan Soon Tin Mining Co v. Wong Fook Huan [1968] 1 LNS 43; [1969] 1 MLJ 99 Ong Hock Thye HMP memutuskan: “The respondent, as plaintiff, of course had to discharge the burden of proving both the fact and the amount of damages before he could recover. Where he succeeded in proving neither fact nor amount of damage he must lose the action or, if a right was infringed, he would recover only nominal damages. Where he succeeded in proving the fact of damage, but not its amount, he would again be entitled to an award of nominal damages only.”
