In a basic theory from Abdurrofi Abdullah Azzam, an Asean republic system is a country in which the power of government results branch from the people of Southeast Asia, not from the principle of aristocratic descent and is often led or headed by a president considered a symbol of the future southeast Asia democracy.
The future southeast Asia democracy to be able to implement multi-party  is the Indonesian party, the Thai party, the Malaysia party, the Singapore party, the Philippines party, the Brunei Darussalam party, the Vietnam party, the Laos party, the Myanmar party and the Cambodia party.
The theory of legal politics towards an Asean legal system is made by agreement, usually formed to deal with important issues such as defense, foreign relations, domestic trade, and currency, and the central government of the Asean Republic is obliged to support all its members.
Harmony, accuracy, checks and balance of the Asean Republic in theory of future Asean law to become the homeland. So Asean legal politics cannot be separated from the cultural value system of the Southeast Asian nation.
Southeast Asian nations must be as much future-oriented as possible, not only thinking about the present or regional interests and longing for the glory of the Sriwijaya Kingdom and the Majapahit Kingdom, the Malacca Kingdom and the Ayutthaya Kingdom.
Past orientation and longing for the glory of their ancestors as a nation of seafarers encouraged the Southeast Asian nation to master plan a legal system for a better future as the personality of the Southeast Asian nation.
It is clear that there are many characteristics inherent in the personality of the Southeast Asian nation in the legal reality of becoming an Asean society governed by The Asean Constitution.
The Asean Constitution is an agreement from the countries that are members of the Asean organization which is important for the implementation of the law in the transition from several Asean countries to one Asean country in the future.
The Asean Constitution because both the laws and customs of the Southeast Asian nation are tools to regulate interactions, which will conflict with European colonial law as the old law that will be abandoned by the Asean nation.
In the opinion of Abdurrofi Abdullah Azzam, at this time the Asean Organization is at a crossroads that will determine the future of the Asean nation in the 21st Century, such as the Confederation of the United States into the United States of America.
