reinforced by article 130 IS, which states that regions are given the freedom to follow
their rules.
After Indonesia's independence on August 17, 1945, the following day, on
August 18, 1945, the 1945 Constitution was enacted. All existing state agencies and
regulations are still valid, as long as a new one has not been established according to
the Constitution.
In the early days of independence, an understanding emerged that wanted to fight
to realize national law by lifting people's rule, namely customary law, into federal law.
The pioneers of this idea are the majority of the old group, an idea put forward by the
previous generation of nationalists, which stated that customary law deserves to be
appointed as modern national law (Wignjodipuro, 1982).
In the 1945 Constitution, there is no single article explicitly stating the
application of customary law in Indonesia. This is different from the Constitution of
the United States of Indonesia, which constitutionally can find items that are the legal
basis for applying customary law, as stated in article 146 paragraph (1), which states
that judicial decisions must contain reasons case of punishment. Must mention
statutory rules and customary law rules on which the sentence is based. Article 146
paragraph (1) the Constitution Republic of the United States of Indonesia is reaffirmed
in Article 104 (1) of the Provisional Constitution of 1950.
The standard configuration has changed, and customary law is an organic part of
state law. This realization is contained in Law Number 4 of 2004 concerning Judicial
Power, which is regulated in article 25 paragraph (1), which states that all court
decisions other than must state the reasons and basis for a said decision, also contain
specific pieces of the relevant laws and regulations or an unwritten source of direction
which is used as a basis for judging. This article is strengthened by article 28, which
states that judges are obliged to explore, follow and understand traditional values and
a sense of justice that lives in society.
From the 2 (two) articles mentioned above, it can be concluded that implicitly
customary law can be used as the basis for judges in adjudicating and deciding cases
in Court because what is meant by the unwritten source of direction in article 25
paragraph (1) is customary law. And what is meant by traditional values and a sense of
justice in society, one of which is established law, assuming that customary law is a
law that grows and develops in the community? These two articles give judges the
authority to decide cases based on customary law.
3. The existence of customary law in the national law system
Customary law grows from the ideals and thoughts of the Indonesian people.
Thus, customary law can be traced chronologically since Indonesia consisted of
kingdoms scattered throughout the archipelago. The socio-cultural reality is
constructed by one poet, been built by another, and reconstructed by the next poet.
