Practice Relating to Rule 71. Weapons That Are by Nature Indiscriminate
The Report on the Practice of India states:
The Geneva Convention norms regarding use of indiscriminate weapons are applicable by virtue of the Geneva Conventions Act. Although it is not specifically made applicable to internal conflicts, yet it is possible to suggest on the basis of the practice of not using such weapons that in India such weapons are prohibited in times of internal conflict.
