The Federal Court in Low Lee Lian v Ban Hin Lee Bank Bhd [1997] 1 MLJ 77 at 85 - 86 explained : In the present context, an action brought to set aside a charge upon one or more of the grounds of defeasibility specified under s 340 of the Code is an action in rem. For when it succeeds, the consequence is to set at naught the chargee's rights under the registered charge as against the whole world. On the other hand, a chargor who is able to demonstrate that the chargee is under a personal obligation that binds his conscience not to enforce the charge, though not in a position to bring his case within one or more of the exceptions to the indefeasibility provision may nevertheless proceed to enforce that obligation against the chargee. This is an action in personam. The consequences of succeeding in such an action will have the effect of getting the charge to defeat his own title or of depriving him of some or all of his rights under the registered charge, including the right to obtain an order for sale. See Oh Hiam & Ors v Tham Kong [1980] 2 MLJ 159. The important distinction between the enforcement of rights ad rem and rights in personam in the context of the Code was explained by the Court of Appeal in Luggage Distributors (M) Sdn Bhd v Tan Hor Teng & Anor [1995] 1 MLJ 719 at p 758. We accept that what was there said correctly states the law upon the subject : To summarize, a claimant to any title or registrable interest in land may frame his case in one of two actions. If the facts pertaining to his claim enable him to bring his case within those vitiating categories specified under s 340 (2) of the Code, then he may frame his case under one or more of those categories as an action in rem. If on the other hand, he is unable to bring himself squarely within the exceptions in favour of defeasibility, then, all is not lost to him: for, if he is able to constitute his complaints as an action in personam he may achieve the same result. Of course, as an action in personam, his claim may be subjected to all those discretionary considerations that operate in the grant or refusal of specific relief. In either case, he may be entitled to secure the status quo by the entry of a private caveat.
