Do treaties have to be incorporated into domestic law before they take effect?
Yes. Treaties must be incorporated into domestic law before they can take effect in the country. In order to become domestic law and enforceable, treaties must first be approved by the Legislative before being ratified. If a treaty affects constitutional dispositions, the process for approval and ratification must follow the same process as for constitutional amendments. The Executive branch may sign and ratify international agreements in matters of its competence without prior approval by Congress, but must inform Congress immediately of this.
