Considering that the provisions of Article 28I paragraph (1) of the 1945 Constitution, state that the right not to be prosecuted under retroactive law is a human right that cannot be reduced under any circumstances.

Although the literal formulation gives the impression that the right not to be prosecuted under retroactive law is absolute, in accordance with its drafting history, Article 28I paragraph (1) must not be read in isolation but must be read together with Article 28J paragraph (2).

In this way, it will be apparent that, systematically, human rights - including the right not to be prosecuted under retroactive law - are not absolute, because in exercising their rights and freedoms, everyone is obliged to respect the human rights of others and is obliged to comply with restrictions determined by law solely for the purpose of guaranteeing the enforcement and respect for the rights and freedoms of others and to meet just demands in accordance with moral considerations, religious values, security and public order in a democratic society as regulated in Article 28J paragraph (2).

By reading Article 28I paragraph (1) together with Article 28J paragraph (2), it is clear that the right not to be prosecuted under retroactive law is not absolute, so that in order to "meet just demands in accordance with moral considerations, religious values, security, and order", it can be set aside;

If we trace its history further, the Dutch East Indies government in exile in Australia also once enacted a retroactive rule by issuing a rule called the Brisbane Ordonnantie 1945, namely a rule regarding the application of criminal acts against state security which aims to carry out criminalization against parties who have politically experienced war defeat, namely the Japanese army and its collaborators.

The enforcement of the retroactive principle at that time aimed to carry out a broad political domination of other parties who were considered as opponents.

Meanwhile, the application of the retroactive principle at that time was a recognition of the existence of the Lex Talionis (retaliation) principle. The nature of political retaliation as an attitude of Lex Talionis is reflected in the considerations of the military court decision which stated, among other things: "because the Allied forces will chase him to the ends of the earth to eventually be handed over to the prosecution because the law will be upheld".

After independence, the Constitution of the Republic of the United States of Indonesia (RIS Constitution) also recognized the application of retroactive legal rules. This can be seen in the transitional provisions of Article 197 paragraph (2) of the RIS Constitution which reads

if and only before the time mentioned in paragraph (1), actions have been taken to form the equipment of the Republic of the United States of Indonesia and to prepare for the acceptance of sovereignty, all on the basis of the provisions of this Constitution, then these provisions apply retroactively to the day the actions in question were taken.

The issue of applying the retroactive principle was again debated when Law Number 39 of 1999 concerning Human Rights and Law Number 26 of 2000 concerning the Human Rights Court were issued. The explanation of Article 4 of Law 39/1999 states that the application of this retroactive principle is permitted, it is explained that

….The right not to be prosecuted on the basis of retroactive law may be waived in the event of gross violations of human rights classified as crimes against humanity.

Interestingly, the Explanation of Article 4 of Law 39/1999 is actually contradictory to the wording of Article 4 of Law 39/1999 which states that “….the right not to be prosecuted on the basis of retroactive law is a human right that cannot be reduced under any circumstances and by anyone.”

Another provision, namely Article 43 paragraph (1) of the Human Rights Court Law readsSerious human rights violations that occurred before the enactment of this Law shall be examined and decided by the Ad Hoc Human Rights Court."

If observed, the provisions of Article 43 of the Human Rights Court Law do not explicitly state that these provisions can be applied retroactively. However, in substance, the provisions of Article 43 paragraph (1) which reads regarding all acts (serious human rights violations) that occurred before the enactment of this Law are examined and decided by the Ad Hoc Human Rights Court, then these provisions can be substantially applied retroactively after the DPR determines a certain event. that.

What is decided by the DPR about a “certain event” in relation to paragraph (1) in logical thinking can be ascertained is every event of serious human rights violations that occurred before the enactment of this Law, namely serious human rights violations that occurred before November 23, 2000.

Another provision regarding the application of the retroactive principle can also be seen in Article 46 of Government Regulation in Lieu of Law Number 1 of 2002 concerning the Eradication of Terrorism Crimes in the Bali Bombing Incident on October 12, 2002.

In the provisions of Article 46 of Perppu Number 1 of 2002, it is emphasized that “The provisions in this Government Regulation in Lieu of Law can be applied retroactively for legal actions for certain cases before this Government Regulation in Lieu of Law comes into effect, the application of which is determined by a separate Law or Government Regulation in Lieu of Law."

If observed grammatically, the sentence “…can be applied retroactively for legal actions for certain cases before this Perpu comes into effect, …” contains a signal that this provision opens up the possibility of retroactively applying it to acts of terrorism other than the Bali Bombing incident on October 12, 2002.
