Practice Relating to Rule 92. Mutilation and Medical, Scientific or Biological Experiments
Switzerland’s Basic Military Manual (1987) provides that “medical and scientific experiments” run counter to the obligation of humane treatment and prohibits medical and scientific experiments other than those required for medical reasons. It adds that conducting biological experiments on persons protected by the 1949 Geneva Conventions constitutes a grave breach of these instruments.

In 2005, in a report in response to a parliamentary postulate on private security and military companies, Switzerland’s Federal Council stated:
International humanitarian law is aimed not only at states. It also contains numerous provisions for individuals and even civilians to observe. Perhaps the most well known example is Article 3 common to all four Geneva Conventions, according to which persons taking no active part in the hostilities, including members of armed forces who have laid down their arms and those placed “hors de combat” by sickness, wounds, detention, or any other cause, shall in all circumstances be treated human[e]ly, without violence to life and person, in particular mutilation, torture and cruel treatment.

In 2010, in its Report on IHL and Current Armed Conflicts, Switzerland’s Federal Council stated:
3.4 [Increasing use] of anti-guerrilla tactics
Apart from the direct fight against insurgents, international humanitarian law also addresses other anti-guerrilla tactics. … If members of militias or opposition groups fall into the hands of the government they benefit from the protection of art. 75 of [the 1977] Additional Protocol I as well as that of art. 3 common to the [1949] Geneva Conventions.

In 2012, in a statement before the UN Security Council during a debate on children and armed conflict, the permanent representative of Switzerland stated:
[T]he situation of children affected by armed conflict remains alarming on a global scale. Children continue to be … maimed …
Pressure must be increased on persistent perpetrators. To that end, a close cooperation between the Security Council and national and international courts seeking to end impunity for serious violations of international humanitarian law is vital.
