Paul consults the specialist doctors at a private hospital. He complains of a severe headache. The doctors examine him but unfortunately, they fail to detect a tumour that was growing on his brain. They tell him that there was nothing serious with his medical condition. Eight months later he is diagnosed with advanced brain cancer by specialists in another hospital.

He is very upset and wishes to take legal action against the doctors and hospital for their negligence.
