At the CDDH in 1975, when it introduced an amendment to what became Article 32 of the 1977 Additional Protocol I, Germany, on behalf of the sponsors (Germany, United Kingdom and United States), stated:
To mitigate the suffering of the families of those who disappeared in war by removing the uncertainty about their fate and to give them an opportunity to remember their dead in the place where their remains lay was a fundamental humanitarian principle. Such principle was already included in the … Oxford Manual of 1880 and in the Hague Regulations of 1899 and 1907 and in the Geneva Conventions of 1906, 1929 and 1949.

In 2005, in its Seventh Human Rights Policy Report, Germany’s Federal Government reported to the Bundestag (Lower House of Parliament):
With the 1998 guidelines on the handling of crises related to internally displaced persons (“Guiding Principles on Internal Displacement”) by the then Representative of the UN Secretary-General on the Human Rights of Internally Displaced Persons, Francis Deng, the international community has a practice-oriented document, which summarizes existing standards on the protection of internally displaced persons and gives further recommendations. Although these guiding principles are not a binding instrument under international law, their acceptance by States, international organizations and NGOs has continued to grow over the past years, so that now they are virtually regarded as customary international law.
