However, the requirement that a person should be offered opportunity to defend himself after being charged need not necessarily be in the form of a trial involving oral testimonies i.e. examination-in-chief and cross examination. What is required is to afford him the opportunity to rebut, correct or contradict what is alleged against him. The principle of natural justice is satisfied if the person accused is allowed to correct or rebut what is prejudicial to him in writing.
