The rules governing the order was since revised several times. Gazette notices establishing the Rules that instituted the Order were published in 1975, 1996 and 2019.[1][2] The 1996 Rules would revoke the 1975 Rules.[1] With the 1996 Rules, there would be 3 grades of the Order, First Class, Second Class and Third Class.[1] Only Singapore citizens could be admitted to the Order, with non-Singapore citizens being admitted in an honorary capacity.[1] The First Class grade would have a limited capacity of twelve members, whilst the other grades have no such restriction.[1] The Seal of the Order would bear the design of the Badge.
