"The electoral law should seek to strengthen the autonomy of the management structure by ensuring that the appointments procedure delivers persons of high standing who have a proven sense of fairness and impartiality. The senior members of management (e.g., members of the electoral or constituency boundaries commission) should be answerable to parliament and not to the prime minister or president, as the head of government. The members’ tenure of office should be secure and their removal should be governed by clearly stipulated procedures, possibly requiring a resolution by the national assembly, not dissimilar to those applicable to the removal from office of a supreme court judge.” … “The electoral law should be designed in a manner so as to ensure that appointments at all levels in the electoral system are aimed at selecting people who are honest, impartial and efficient."
