AbstractWhile all international human rights treaties apply to children, only the Convention explicitly elaborates who is defined as a child. Article 1 defines the child as a human being who is below the age of 18 years. Majority is set at age 18 unless, under domestic law, it is attained earlier. During the negotiations of the text of the Convention, there was significant debate regarding definitions of both the commencement and the ending of childhood. The initial text, proposed by the Polish Government, drawing on Principle 1 of the UN Declaration of the Rights of the Child, 1959, provided no definition of childhood at all (Office of the United Nations High Commissioner for Human Rights and Rädda barnen (Society: Sweden), 2007, p. 301). However, government delegates on the Working Group immediately highlighted the need for clarification. The first revision of the text therefore proposed that a child is a human being from birth to the age of 18 years unless majority is attained earlier. However, with regard to the beginning of childhood, the Working Group were unable to come to a consensus. An unresolvable division persisted on whether childhood, in respect of the Convention, commenced from the point of conception, or from birth (Office of the United Nations High Commissioner for Human Rights and Rädda barnen (Society: Sweden), 2007, pp. 301–313). The conflict was ultimately resolved by removing any reference to the start of childhood.
