Practice Relating to Rule 11. Indiscriminate Attacks
The Report on the Practice of Brazil states that Brazil has ratified the 1949 Geneva Conventions and their 1977 Additional Protocols and that, under the Brazilian Constitution, treaties become part of domestic law once ratified by the Congress and published in the official journal. Therefore, the rules pertaining to indiscriminate attacks as set forth in these treaties are binding upon Brazil.
