# Geneva Conventions Act 1957, ARTICLE 42


The internment or placing in assigned residence of protected persons may be ordered only if the security of the Detaining Power makes it absolutely necessary.
If any person, acting through the representatives of the Protecting Power, voluntarily demands internment, and if his situation renders this step necessary, he shall be interned by the Power in whose hands he may be.
