The mental capacity of LLT when the Codicil was executed is crucial. The Plaintiffs rely on the evidence of EH that LLT’s speech was “clear and his instructions were very specific. He was lucid.” They also relied on the evidence of LLT’s nurse, John Leong (“Nurse Leong”), who testified that he had always known LLT to be “very mentally alert and had a fairly good memory” and that “[he] never observed any issue with or deterioration in his mental ability, alertness and rationality”. On the contrary, the Opposing Defendants relied on records of the nurse who took the night shift when Nurse Leong was off duty, where the night nurse noted on multiple occasions that LLT had lapses in his memory. The specific phrase used was “memory on and off”. It was noted that LLT “forgot the dinner” on one occasion. Counsel for the 1st and 2nd Defendants suggested that LLT’s memory lapses might have been caused by the medication he was taking, but as I indicated to counsel during trial, such an assertion would only be of utility if backed by the testimony of an expert, of which none was called. Furthermore, Nurse Leong was quick to refute that suggestion when he took the stand. He testified that he had been helping to administer the medication for LLT and he recalled vividly that LLT was mentally alert to his own affairs. He rejects Mr Ong’s suggestion that LLT was mentally unsound because he had forgotten whether he had his dinner on one occasion. During cross-examination, it was suggested to Nurse Leong that LLT was fairly lethargic given the number of naps he took each day. Nurse Leong disagreed, and stated that it was common for patients of LLT’s age to take naps, and that it does not indicate a “mental lethargy”. Furthermore, he testified that LLT was coherent, sound, and mentally alert in all the time he had looked after him. This was not a nurse who filled in one or two occasions but a regular nurse who had worked for LLT for three years, beginning in 2006. He appeared to me forthright and professional, and I have no hesitation in accepting his evidence.
