The Civil Code is seemly unconstitutional law because in the Cambodian constitution stated in article 93 New (As amended March 20009) that “Any law approved by the assembly and finally reviewed by the Senate and signed by the King for its promulgation shall go into effect in Phnom Penh ten days after its signing and throughout the country twenty days after its signing. Laws that are stipulated as urgent shall take effect immediately throughout the country after promulgation. Laws that are signed by the King for its promulgation shall be published in the official journal and announced it to the public throughout the country”. However, it is a new context of law progress in Cambodia. Let see together.
