In Freemasonry, an official act is said to be done, according to the rank of the person who does it, either in ample form, in due form, or simply in form. Thus, when the Grand Lodge is opened by the Grand Master in person, it is said to be opened in ample form; when by the Deputy Grand Master, it is said to be in due form; when by any other qualified officer, it is said to be in form. The legality of the act is the same whether it be done in form or in ample form; and the expression refers only to the dignity of the officer by whom the act is performed. The terms Ample and Due Form appear to have been introduced by Anderson in the 1738 edition of the Constitutions (page 110).
