Introduction

[1] This is an application by the second to fourth defendants, Tan Sri Dato' (Dr) Rozali Ismail, his brother Mat Hairi Ismail and WWE Holdings Bhd (a company controlled by the brothers), to set aside previous orders of the High Court dated 25 and 27 April 2012 by which:

(a) the first defendant, Lim Pang Cheong @ George Lim, was found to be mentally disordered within the meaning of the Mental Health Act 2001 ; and

(b) the plaintiff, Gary Lim (who is the son of George Lim) and Loh Foh Fin, the wife of George Lim, were appointed as the committee of George Lim's person and estate.

[2] For ease of reference, the second to fourth defendants are referred to as the judgment creditors (for reasons that will shortly be apparent), while George Lim is referred to as the first defendant. The plaintiff and the committee (acting for the first defendant and his estate) were represented by the same counsel, whom I will refer to simply as the counsel for the plaintiff. References to the plaintiff should be taken to include a reference to the committee of the first defendant and of his estate, unless the context requires otherwise.
