Potential Undue Influence Case

Linda, a diligent factory operator, has been facing a cascade of personal tragedies. Her husband, the family's primary breadwinner, passed away unexpectedly, leaving her to fend to the household alone. Her only child was left paralysed and mentally affected because of prolonged and severe illness. However, medical expenses are astronomical. Linda is now burdened with outstanding medical bills that threaten to overwhelm her modest income. Linda turned to Mahmud, a long-time friend and successful businessman known for his acumen in financial consultancy. Over the years, Linda has relied on Mahmud's expertise to navigate her financial decisions, seeking counsel on investment portfolios to secure her family's future. Trusting his judgment, she found advice and suggestions to be beneficial. Linda shared her current predicament with Mahmud and proposed a practical solution. He advised Linda to consider selling a piece of land she inherited from her mother. This land, located in a developing area with the potential for future growth, was a significant asset to Linda, holding monetary value and sentimental attachment. Mahmud, aware of Linda's urgent need for funds and perhaps recognising the land's actual worth, offered to purchase it himself. He presented the sum of RM300k, which Linda accepted under pressing circumstances without much deliberation. They formalised their agreement through a written contract that was legally binding to the transaction. However, through conversations with real estate experts and further investigation, she realised that the land's market value far exceeded the agreed upon price. In fact, it was worth over RM600k, double Mahmud's offer. This revelation brings to light the possibility that Mahmud, with his business acumen and knowledge of the market, might have taken advantage of Linda's vulnerable state to secure a deal well below the land's actual value. Apply the principles of commercial law by mistakes to the facts of the case above.
