As a Legal Officer, she functions directly as a personal adviser to the President rather than being an official of the UN's main Legal Department. Diplomatic analysts and former ambassadors explain that the role involves advising the President on procedural rules, resolution submissions, point-of-order rulings, and amendment acceptances during sensitive global discussions (such as on Palestine or Ukraine), ensuring the President remains impartial and decisions are legally sound under the UN Charter. Additional duties include coordinating with legal bodies, drafting speeches on legal or international treaties, and ensuring all presidential actions comply with UN rules. The official UN profile notes that Zaima Rahman is a barrister and policy expert holding an LLB from Queen Mary University of London, called to the Bar from The Honourable Society of the Inner Temple in England and Wales, and enrolled as an advocate in Bangladesh, alongside having previous legal, pro bono, and policy advisory experience. Former Ambassador Munshi Faiz Ahmed noted that while it serves as a valuable opportunity for her to gain international experience, the appointment falls entirely within the presidential prerogative and matches the required qualifications.
