The article states :
The practice clearly engages the right to manifest one’s religious beliefs, as guaranteed by Article 9 of the Human Rights Convention, and possibly the right to a private and family life in Article 8. However, these rights are qualified and may be restricted in certain circumstances.
HUMAN RIGHTS ARE LIMITED TO THE RIGHTS OF THE INDIVIDUAL
The article 9 cited is :
ARTICLE 9 Freedom of thought, conscience and religion
1. Everyone has the right to freedom of thought, conscience and religion; this right includes freedom to change his religion or belief and freedom, either alone or in community with others and in public or private, to manifest his religion or belief, in worship, teaching, practice and observance.
2. Freedom to manifest one’s religion or beliefs shall be subject only to such limitations as are prescribed by law and are necessary in a democratic society in the interests of public safety, for the protection of public order, health or morals, or FOR THE PROTECTION OF THE RIGHTS AND FREEDOM OF OTHERS. *
The freedom of religion doesn't superseed the rights and freedom of the baby, mainly to be free from mutilation.
ARTICLE 8 Right to respect for private and family life
1. Everyone has the right to respect for his private and family life, his home and his correspondence.
2. There shall be no interference by a public authority with the exercise of this right except such as is in accordance with the law and is necessary in a democratic society in the interests of national security, public safety or the economic well-being of the country, for the prevention of disorder or crime, for the protection of health or morals, or FOR THE PROTECTION OF THE RIGHTS AND FREEDOM OF OTHERS. *
The rights to family life doesn't invalidate the rights to be free from mutilation.
The right to a family life stop when the rights of the children begin; that is fundamental and the basis for all anti child abuse law in every civilized country.
In particular, proponents of a ban on infant circumcision argue that it is necessary to ensure the protection of the rights of children. Although there is no ‘right to protection of one’s bodily integrity’ in the Human Rights Convention, it has been suggested that such a right might be expressed via Article 3 (prohibition of inhuman or degrading treatment) or Article 5 (the right to liberty and security).
This article gave a balanced representation of the two sides but still there is no rights to mutilate someone else's body under no circumstances, under no human rights article neither freedom of religion nor right to a family.
