Does the constitution specifically allow a son of a Mason to be initiated at a tuner age than usual?

Historically, the son of a Mason—known as a Lewis or Louveteau—held a specific standing, though practices vary between traditions. In French and Continental practice, a formal lodge ceremony of adoption provided the child with a document that served as a dispensation exempting him from ordinary preliminary examinations when he reached the proper age to seek initiation 1.

Under current guidance from the United Grand Lodge of England, a Lewis is defined as the uninitiated son of a Mason; while he receives seniority in ceremonial ordering when two candidates are initiated on the same day, he cannot claim precedence over candidates who were previously proposed or elected. Regarding the age requirement itself, Rule 157 in the Book of Constitutions of the United Grand Lodge of England lowered the standard general age of initiation for all candidates to 18 without requiring a dispensation.
