Which is a requirement under the CCP regarding international treaties?

The correct answer highlights that international treaties must be adhered to in legal matters. This requirement underscores the importance of upholding international obligations that a country has entered into through treaties. Under the principles of international law, treaties are binding agreements between sovereign states and must be honored by the signatory countries. In the context of the Code of Criminal Procedure, this is significant as it ensures that individuals, including foreign nationals, are afforded rights and protections that might stem from treaties related to criminal justice, human rights, and extradition.

Other options present misconceptions. The idea that treaties are optional unless specified implies a lack of obligation that undermines their binding nature. The notion that all treaties are invalid in criminal cases grossly misrepresents the capacity for treaties to influence legal frameworks and procedures. Lastly, stating that treaties are only valid if both countries agree suggests a misunderstanding of the process; once a country ratifies a treaty, it is bound to follow the treaty’s terms regardless of ongoing agreements or disagreements with other nations.
