a certain minimum degree of regularity and certainty, for without that it would be
impossible to assert that what was operating in a given territory amounted to a legal
system” From this view, it can be understood that without legal certainty, people do
not know what to do and ultimately uncertainty arises (uncertainty) which will
ultimately lead to violence (chaos) due to the indecisiveness of the legal system. So,
legal certainty refers to the application of law that is clear, permanent, and consistent,
where its implementation cannot be influenced by subjective circumstances (Prayogo,
2016).
b. Proof Theory
Article 163 HIR (289)RBg) as well as Article 1865 of the Civil Code states that: "Every
person who postulates that he has a right, or to confirm his right or dispute another
person's right, refers to an event, is obliged to prove the existence of that right or
event." Therefore, proof can be defined as an effort to provide certainty in
meaningkehukuman, providing a sufficient basis for the judge regarding the validity
of an incident brought forward by the litigant in a formal manner, meaning it is limited
to the evidence presented at the trial (Saepullah, 2018).There are 3 (three) theories for
judges when justifying the evidence put forward by the parties:
1) Free Evidence Theory
The following theory wants as much freedom as possible for judges in justifying
evidence. Judges are not bound by legal provisions, or at least the amount of
binding by legal provisions must be limited to as small as possible. Wanting broad
freedom means giving trust to judges to be impartial, honest, full of responsibility,
act with expertise, and not be influenced by anything or anyone.
2) Negative Proof Theory
This theory wants binding provisions, which are negative. This provision limits
judges by prohibiting them from doing anything related to evidence. So judges are
prohibited by exception. (Article 306RBg/169 HIR, Article 1905 Civil Code)
(Amiruddin & Hasyim, 2014). Article 306 RBg/169 HIR states: "The testimony of a
single witness, without any other evidence, cannot be trusted in law." Article 1905 of
the Civil Code states: "The statement of a single witness, without any other
evidence, may not be trusted before a court."
3) Positive Proof Theory
Apart from the existence of prohibitions, the following theory is desirable presence
of an order to the judge. Judges are required but with conditions (Article
285RBg/165 HIR, Article 1870 Civil Code) (Putra & Yahya, 2022).
Article 285 RBg/165 HIR states:
"Authentic deed, namely a letter made according to the provisions of the law by or in
front of a public official who has the power to make the letter, providing sufficient
evidence for both parties and their heirs and all people who have rights from it,
regarding all matters what is stated in the letter, and also what is stated in the letter as
