The National Order of Merit pays tribute to Maltese citizens who distinguish themselves in different fields of endeavour. The motto of the Order is Virtute et Constantia. Only Maltese citizens are eligible to be appointed members of the Order. However, honorary membership may be conferred on foreign nationals who have distinguished themselves by their service in the promotion and fostering of international relations, or who have earned the respect and gratitude of the people of the Maltese Islands. In addition to past and present presidents and prime ministers who are by virtue of their offices members of the National Order of Merit in the grade of Companion of Honour, there can be only three other members in this grade at any one time. In the other grades the maximum at any one time is twelve Companions, twenty Officers and one hundred Members. Annual appointments may not exceed two Companions, three Officers and ten Members, provided that in determining the number of appointees to the Order, no account shall be taken of the appointment of Honorary Members.
