The General Conference of the International Labour Organisation,

Having been convened at Geneva by the Governing Body of the International Labour Office, and having met in its Fifty-eighth Session on 6 June 1973, and

Having decided upon the adoption of certain proposals with regard to minimum age for admission to employment, which is the fourth item on the agenda of the session, and
