A barrister is not bound to disclose evidence favourable to the other side to the court. He would fail in his duty to his own client were he to supplement the deficiencies in his opponent’s evidence although he must draw all relevant decisions and legislation to the court’s attention. The fact that the other side is a litigant in person cannot make any difference as to the manner in which he fulfils his duties to his client, to the other side and to the court – Khudados v Hayden [2007] EWCA Civ 1316.
