This research aims to analyze the consistency of judges' legal reasoning in deciding land ownership disputes and its implications for the fulfillment of the principle of legal certainty. The primary focus of this study is directed at Decision Number 16/PDT/2020/PT PLG, where differences in legal perception or evidentiary evaluation occurred at the appellate level. Land disputes are a crucial issue that requires legal firmness to avoid uncertainty for justice seekers. The research method used is normative legal research with a case approach and a statutory approach. Data were sourced from secondary data consisting of primary, secondary, and tertiary legal materials, analyzed qualitatively. The results show that the consistency of the judges' reasoning in Decision Number 16/PDT/2020/PT PLG depends heavily on the accuracy of assessing evidence, particularly documentary evidence (certificates) and witness testimony. Inconsistency between factual considerations and the application of legal norms has the potential to undermine the principle of legal certainty. This study concludes that strengthening the standards of legal reasoning based on the principle of ex aequo et bono and adherence to civil procedural law is absolutely necessary so that judicial decisions do not only resolve disputes procedurally but also provide certainty of ownership rights for thelitigating parties.

This study analyzes the juridical issues related to the implementation of criminal sanctions below the statutory minimum, as reflected in Cassation Decision Number 7853/K/Pid.Sus/2024. The focus of this research centers on the tension between the rigid provisions of Article 111 paragraph (1) of Law No. 35 of 2009 concerning narcotics and the reality of judicial practice, which often deviates from these provisions. This phenomenon raises debates regarding the extent to which the principle of legality can be compromised in pursuit of justice without undermining the pillar of legal certainty within Indonesia’s criminal justice system. Using a normative legal research method with a statutory and case study approach, this study qualitatively analyzes judges’ considerations. The findings indicate that, although the policy of imposing sentences below the minimum carries the risk of creating legal uncertainty, the Supreme Court in this case reinterpreted the principle of legality. Judges tend to prioritize proportionality and substantive justice to avoid purely mechanical punishment. The study concludes that, while judicial discretion represents a concrete expression of judicial independence, such practice requires clearer normative parameters. Without explicit regulation, deviations from the statutory minimum risk widening disparities in judicial decisions. Therefore, standardized sentencing guidelines are necessary to preserve legal integrity while maintaining a sense of justice for defendants.

The doctrine of open legal policy is a jurisprudential construction of the Constitutional Court that provides space for lawmakers to formulate norms as long as they do not contradict the 1945 Constitution of the Republic of Indonesia. Nevertheless, the application of this doctrine in the practice of law testing has raised various constitutional problems, particularly concerning the limits of authority between legislators and the Constitutional Court, as well as the protection of citizens' constitutional rights. This research aims to analyze the concept and construction of open legal policy within the Indonesian constitutional system and to formulate the constitutional limits of its application in Constitutional Court decisions. This research is a normative legal study with an approach based on legislation, a conceptual approach, and a case approach. The legal materials used include the 1945 Constitution, relevant legislation, and pertinent Constitutional Court decisions. The research results indicate that open legal policy cannot be interpreted as absolute freedom for lawmakers, but must be limited by the principle of constitutional supremacy, protection of constitutional rights, and the principle of proportionality as reflected in Article 28J paragraph (2) of the 1945 Constitution. The ambiguity of the parameters for applying this doctrine has the potential to cause inconsistencies in rulings and disrupt legal certainty. Therefore, a more precise and consistent formulation of constitutional limits is necessary to maintain the balance between representative democracy and constitutional oversight.

This study aims to analyze the position of statutory regulations as the main limiting framework for administrative discretion in Indonesian administrative law, particularly after the enactment of Law Number 11 of 2020 on Job Creation. The main issue examined is the normative shift caused by the removal of the requirement that discretion must not contradict statutory regulations, which potentially weakens legal certainty and judicial control. This research uses a normative juridical method with a regulatory and conceptualization approach, and is supported by the theory of discretionary justice, balance of legal objectives, and good governance. The findings indicate that the elimination of formal legality requirements transforms discretion from a legally constrained authority into a broader administrative freedom, increasing the risk of abuse of power and weakening the objective standards of judicial review in administrative courts. The study concludes that such a shift undermines the core principles of the rule of law and necessitates constitutional review to restore legal certainty, accountability, and effective judicial oversight.

Divorce gives rise to various legal consequences relating to the status of the parties, marital property, and the rights and obligations toward children, thereby requiring a legal mechanism that ensures legal certainty, justice, and legal protection. In practice, the parties often express their intention to divorce in the form of a Pre-Divorce Agreement Deed drawn up before a notary. This study aims to analyze the legal standing and evidentiary strength of a Pre-Divorce Agreement Deed as evidence in divorce cases decided by default judgment (verstek). The research employs a normative juridical method with a statutory approach and a case approach, focusing on the Decision of the Ngawi Religious Court Number 425/Pdt.G/2023, through a literature review of primary and secondary legal materials. The findings indicate that a Pre-Divorce Agreement Deed executed in the form of a notarial deed constitutes an authentic deed with perfect evidentiary value as written evidence in divorce proceedings. Although it cannot directly result in the dissolution of marriage, the deed is relevant to prove the existence of an agreement between the parties and the condition of a marital relationship that has irretrievably broken down. In cases decided by default judgment, the deed becomes an important basis for judicial consideration in granting the divorce petition. The implications of this study emphasize that a Pre-Divorce Agreement Deed may be lawfully and proportionately used as evidence to support the proof of grounds for divorce and to realize legal certainty in judicial proceedings.

This study aims to analyze the implementation of good governance principles in inclusive public services in Candisari District, Semarang City. The study used a descriptive qualitative approach with data collection techniques through questionnaires, interviews, and documentation. Research informants consisted of sub-district officials and community service users, including vulnerable groups. Data analysis was conducted through the stages of data reduction, data presentation, and conclusion drawing. The results of the study indicate that the implementation of good governance principles in Candisari District has begun, but has not been running optimally. The principle of transparency has been attempted through the provision of service information and the use of digital media, but accessibility of information for vulnerable groups is still limited. The principle of accountability has not been fully realized, as indicated by the less than optimal performance of the Women and Children Protection Task Force (Satgas PPA) in carrying out its duties and the less than optimal inclusive public complaint mechanism. From the aspect of participation, community involvement, especially vulnerable groups, in the planning and decision-making process is still limited and unstructured. In addition, legal certainty and regional security stability are relatively conducive, but still require institutional strengthening and synergy between stakeholders. This study concludes that the implementation of good governance in Candisari District still faces institutional, participation, and service accessibility constraints, so a strategy is needed to strengthen governance to realize inclusive and sustainable public services.

The phenomenon of mafqud (missing heirs) creates complex legal issues within Islamic inheritance law, particularly regarding the realization of justice and legal certainty in the distribution of estate assets. This study examines the legal position of mafqud as a temporary impediment in inheritance allocation and analyzes the procedural mechanisms applied by religious courts in determining mafqud status. Employing a normative juridical method, this research relies on primary legal materials, including the Qur’an, Hadith, classical fiqh references, and relevant judicial decisions, supported by secondary materials such as academic books and scholarly journals. The findings indicate that mafqud serves as a temporary barrier to inheritance distribution, requiring careful judicial assessment to ensure the protection of all heirs’ rights while remaining consistent with Islamic legal principles and the applicable national legal system. Therefore, structured and systematic procedures implemented by religious courts play an essential role in guaranteeing both justice and legal certainty in inheritance disputes involving mafqud.

The issuance of billboard installation permits is part of local government authority in regulating public space, maintaining public order, and ensuring legal certainty. This study examines the implementation of billboard permit administration under Serang City Regional Regulation Number 3 of 2021. It applies an empirical juridical method with a qualitative approach. Data were collected through interviews with relevant local officials and a review of applicable laws and supporting legal materials. The findings indicate that the permit process involves several agencies: the Investment and One-Stop Integrated Service Office as the licensing authority, the Public Works and Spatial Planning Office for technical recommendations, the Regional Revenue Agency for tax collection, and the Municipal Police for supervision and enforcement. Although the regulatory framework is comprehensive, challenges remain, including inter-agency coordination, tax compliance, supervision effectiveness, and limited legal awareness among business actors. The study concludes that effective permit administration depends not only on clear regulations but also on strong institutional coordination and proper implementation.

Bankruptcy is a legal mechanism used to resolve a debtor's inability to fulfill debt obligations collectively, orderly, and fairly through a court decision. In the Indonesian bankruptcy system, the curator has a central role in managing and settling bankrupt assets to protect the interests of creditors while providing legal certainty for debtors. This study aims to analyze the regulation of the curator's authority in managing and settling bankrupt assets and to examine its implications for the protection of creditors’ and debtors’ rights from a business law perspective. The research method employed is normative legal research with statutory and conceptual approaches, conducted through a literature review of various relevant primary, secondary, and tertiary legal materials. The results indicate that the curator’s authority is expressly regulated in Law Number 37 of 2004 concerning Bankruptcy and Suspension of Debt Payment Obligations, which provides a legal basis for the curator to manage, secure, sell, and distribute bankrupt assets to creditors in accordance with legal provisions. However, in practice, several obstacles remain, such as difficulties in tracking assets, potential conflicts of interest, and a lack of transparency, which may affect the effectiveness of legal protection. Therefore, the professionalism of the curator and the supervision of the supervising judge are crucial factors in ensuring legal certainty, fairness, and efficiency in the bankruptcy process.

The implementation of the Global Minimum Tax (GMT) through Pillar Two of the OECD/G20 marks a fundamental change in the international tax architecture, especially for developing countries such as Indonesia. One of the key instruments in Pillar Two is the Qualified Domestic Minimum Top-Up Tax (QDMTT), which provides an opportunity for source countries to retain the right to tax the profits of multinational companies with an effective tax rate below 15 percent. This study aims to analyze Indonesia's readiness to face the implementation of GMT through the QDMTT policy, focusing on regulatory aspects and tax administration capacity. The research method uses literature studies with a qualitative-descriptive approach through the analysis of policy documents, tax regulations, as well as academic literature and international reports. The results of the study show that Indonesia's readiness is still in the transition stage. In terms of regulation, Indonesia has shown an initial commitment through the issuance of PMK Number 136 of 2024, but the regulation still needs to be strengthened at a higher level of regulation for long-term legal certainty. From the administrative aspect, the main challenges include the complexity of calculating jurisdiction-based Effective Tax Rates, cross-border data management, as well as increasing the capacity of human resources and information technology infrastructure. This study concludes that the success of QDMTT implementation in Indonesia depends on strengthening regulations, increasing tax administration capacity, and reformulating sustainable investment policies.

The digital transformation of Indonesia’s judicial system through the implementation of e-court represents a judicial reform aimed at achieving a simple, fast, and low-cost legal process. However, the digitization of civil case proceedings raises concerns regarding legal certainty, particularly in the application of the principle of audi et alteram partem as a fundamental doctrine ensuring equal opportunity for parties to be heard. This study aims to analyze the normative regulation of the audi et alteram partem principle in Indonesian civil procedural law, examine its implementation within the e-court system, and assess whether its application provides adequate legal certainty for litigants. The research employs a normative juridical method using statutory and conceptual approaches. Legal materials consist of statutory regulations, legal doctrines, and relevant academic journals. The findings indicate that normatively, the e-court system accommodates the right to be heard through electronic case registration, summons, hearings, and submission of documents. Nevertheless, technical obstacles, disparities in digital literacy, and potential deficiencies in electronic notification mechanisms may affect the effective protection of parties’ rights. It is concluded that the implementation of the audi et alteram partem principle in e-court has a sufficient legal foundation, yet requires further technical and regulatory strengthening to ensure optimal legal certainty.

This study examines the juridical aspects of guardianship applications by parents to obtain permission to sell a minor’s inherited land and analyzes the judicial considerations in Decision Number 199/Pdt.P/2025/PN Blt. The research employs an empirical juridical method with a sociological legal approach. Primary data were collected through interviews and case documents at the Blitar District Court, while secondary data consist of statutes, doctrine, and related literature. Qualitative-descriptive analysis was applied to interpret the findings. The study reveals that the guardianship application process involves both administrative and judicial stages. Judges scrutinize material evidence and the probity of sale objectives, weighing important principles such as utility, legal certainty, fairness, and justice. Guardians are granted limited authority to sell a minor’s property only if it can be proven to be in the child's best interest and legal protections are assured. Recommendations include strengthening post-decision monitoring, enhancing legal outreach, improving procedural transparency, and ensuring comprehensive implementation.

This study aims to examine the judge's considerations in rendering decisions in aggravated theft cases at the Medan District Court, with an emphasis on the balance between legal and non-legal aspects in realizing substantive justice. The issue of disparate sentencing that frequently arises is the main background of this study. The methods used are an integrated normative legal approach and an empirical legal approach. The normative approach is used to examine the provisions of Article 363 of the Criminal Code (KUHP) and the legal principles that govern the judge's considerations, while the empirical approach is carried out through direct observation of the trial process and analysis of the judge's decision. The results of the study indicate that the judge in case Number 1110/Pid. B/2025/PN Medan not only complied with legal aspects such as fulfilling the elements of the crime, evidence, and the application of the principle of legality, but also considered non-legal aspects such as the socio-economic conditions, age, and motives of the defendant. These considerations demonstrate the application of the principles of criminal individualization and proportional justice. In addition, the judge also considered moral values ​​and social benefits in his decision, which is in line with Gustav Radbruch's theory of three basic legal values: justice, legal certainty, and utility. This study concludes that the thinking patterns of judges at the Medan District Court reflect a shift toward substantive and restorative justice paradigms. It is recommended that the Supreme Court strengthen integrated sentencing guidelines to avoid disparities in sentencing and encourage the adoption of a rehabilitative approach for offenders with low economic motivations.

The crime of receiving stolen goods, as regulated in Article 480 of the Criminal Code (KUHP), is an offence that plays a crucial role in the continuation of the principal crime, particularly theft. Receivers provide a market for stolen goods, thereby indirectly encouraging perpetrators to continue their actions. This article aims to analyse the implementation of Article 480 of the KUHP in judicial practice, with a focus on proving the element of ‘knowing or reasonably suspecting’ that the goods purchased were obtained through criminal activity. This study uses a qualitative method with a case study approach through direct observation of a trial at the M. District Court. The observations show that the panel of judges successfully proved the defendant's guilt as a fence through a series of trial facts, such as the unreasonable purchase price, consistent testimony from the perpetrator of the theft, and the defendant's own admission that he had been suspicious. The judge's decision, which was lighter than the prosecutor's demands, also reflected considerations of substantive justice and humanity in addition to legal certainty. This study concludes that the effective enforcement of Article 480 of the Criminal Code in court plays an important role in breaking the chain of crime and providing a deterrent effect not only for the main perpetrators but also for those who participate in enjoying the proceeds of crime.

The reform of family law in Indonesia represents an essential response to social developments and the growing demand for constitutional protection of citizens’ rights. Family law, primarily governed by Law Number 1 of 1974 on Marriage, has long been criticized for not fully reflecting substantive justice, particularly for vulnerable groups such as children born outside marriage, persons with mental disabilities, and couples facing complex marital relations. In this context, the Constitutional Court of Indonesia (Mahkamah Konstitusi) plays a crucial role as the guardian of the Constitution by promoting progressive reforms through its landmark decisions. This study examines the implications of five significant Constitutional Court rulings: Decision No. 46/PUU-VIII/2010 concerning the legal recognition of children born out of wedlock; Decision No. 93/PUU-XX/2022 addressing guardianship and the rights of persons with mental disabilities; Decision No. 69/PUU-XIII/2015 allowing post-nuptial agreements; and Decisions No. 68/PUU-XII/2014 and No. 24/PUU-XX/2022 regarding interfaith marriage. These rulings demonstrate a paradigm shift from a rigid legalistic approach toward a constitutional framework grounded in human rights, equality, and substantive justice. Furthermore, notaries hold a strategic position as public officials authorized to draft authentic deeds, serving as a bridge between constitutional values and legal practice. Notaries are not merely administrative actors but are responsible for ensuring that legal documents align with positive law and provide legal certainty and protection for individuals. Therefore, the reform of Indonesian family law should not remain solely at the normative level of Constitutional Court rulings but must be effectively implemented in daily legal practice.

The position of children in marriage plays an important role in family law because it is related to the legal status and fulfillment of children's civil rights. Differences in regulations regarding legitimate children and children born out of wedlock in Indonesian positive law create legal uncertainty, particularly regarding civil relations with biological fathers. This study aims to analyze the legal status of legitimate children and illegitimate children and the changes in the legal paradigm following Constitutional Court Decision Number 46/PUU-VII/2010. This study uses normative legal methods with a statutory and conceptual approach. The results show that before the Constitutional Court decision, illegitimate children only had a civil relationship with their mother and their mother's family, whereas after the decision, illegitimate children can have a civil relationship with their biological father as long as the blood relationship can be legally proven. This decision confirms legal reform efforts to guarantee protection and legal certainty for children without discrimination based on birth status.

This study is motivated by the increasing complexity of financing coordination between the National Health Insurance (BPJS Kesehatan) and supplementary health insurance providers under the Coordination of Benefits (KAPJ) scheme, which creates potential claim disputes and administrative risks for hospitals. Although Minister of Health Decree No. HK.01.07/MENKES/1117/2025 regulates payment allocation and membership verification mechanisms, it does not explicitly recognize pre-admission confirmation as a preventive legal protection instrument. This research aims to analyze the normative position of pre-admission confirmation within the KAPJ framework, conceptualize it as a preventive legal protection mechanism, and formulate a proportional implementation model. The study employs a normative juridical method using statutory and conceptual approaches through literature review of relevant regulations and scholarly works. The findings indicate that pre-admission confirmation possesses implicit normative legitimacy through membership verification obligations and system integration requirements, and functions as a risk allocation mechanism that clarifies payment responsibilities prior to service delivery. Its implementation enhances legal certainty, reduces fraud potential, and minimizes claim disputes, provided that access to emergency medical services remains guaranteed.

The enforcement of election criminal law plays a crucial role in safeguarding democratic integrity and upholding the principle of popular sovereignty. Law Number 7 of 2017 establishes the Integrated Law Enforcement Center (Sentra Gakkumdu) as a coordinated mechanism involving the Election Supervisory Body, the Police, and the Prosecution Service in addressing election crimes. However, in practice, the Gakkumdu system has not fully ensured a balanced realization of legal certainty, substantive justice, and legal utility. This study aims to analyze the problems of election criminal law enforcement within the Gakkumdu system, examine the relevance of the Restorative Justice approach in election law, and formulate a reconstruction of election criminal law enforcement based on this approach. This research employs normative legal research using statutory, conceptual, legal philosophy, and legal policy approaches. The findings indicate that the weaknesses in election criminal law enforcement arise from institutional fragmentation, normative ambiguity, and a legal culture dominated by legalistic and sectoral perspectives. The Restorative Justice approach is considered relevant as it prioritizes substantive justice and the restoration of democratic values. Therefore, reconstructing election criminal law enforcement based on Restorative Justice is essential to strengthening democratic legitimacy and public trust in elections in Indonesia.

Air pollution constitutes a significant environmental problem with far-reaching impacts on public health, quality of life, and ecosystem sustainability, particularly in urban areas and industrial zones in Indonesia. Although the national environmental legal framework has adopted the principle of strict liability through Law Number 32 of 2009 on Environmental Protection and Management, its implementation in air pollution cases continues to face substantial challenges, especially with regard to the proof and assessment of non-material damages. Non-material damages such as disturbances to living comfort, deterioration of environmental quality, psychological stress, and health-related anxiety are intangible in nature and lack clear measurement standards, resulting in their frequent exclusion or inadequate consideration in environmental civil litigation. This study aims to analyze the legal basis for the application of the strict liability principle to air pollution cases in Indonesia, identify relevant forms of non-material damage, and examine the implications of the absence of standardized methods for assessing such damages on legal certainty and the effectiveness of corporate liability enforcement. The research employs a normative legal research method with a library-based approach, incorporating statutory, conceptual, and case approaches. Legal materials are analyzed qualitatively using a descriptive-analytical method, drawing upon legislation, court decisions, and scholarly literature on environmental law and environmental damage valuation. The findings indicate that the absence of standardized criteria for assessing non-material damages leads to evidentiary difficulties, inconsistent court decisions, and a weakened deterrent effect on polluting corporations, thereby preventing the full realization of victims’ rights to effective remedies. This study underscores the urgency of developing an integrated national technical guideline for the assessment of non-material environmental damages based on scientifically grounded valuation methods, as well as the need for cross-institutional policy harmonization to strengthen legal certainty, access to justice for affected communities, and corporate accountability in controlling air pollution.

Law Number 11 of 2006 on the Governance of Aceh embodies the principle of lex specialis due to its territorial scope, while Law Number 4 of 2009 on Mineral and Coal Mining also contains a lex specialis character as it specifically regulates the mining sector. This situation raises a legal question regarding how the principles of lex specialis derogat legi generali, lex superior derogat legi inferiori, and lex posterior derogat legi priori should be interpreted and applied by the Government within the framework of Aceh as a Special Autonomous Region. This study aims to conduct an in-depth legal analysis using a progressive law approach to examine whether the principles of lex posterior or lex superior may override the principle of lex specialis as applied in Aceh’s special autonomy regime. The research employs normative legal methods with qualitative analysis. The findings indicate that the principle of lex specialis derogat legi generali as stipulated in the Law on the Governance of Aceh must take precedence due to its specific territorial applicability and special autonomous status. In resolving such normative conflicts, a clear legal framework is required, accompanied by the renewal of legal theories and principles to ensure legal certainty, prevent regulatory overlap, and promote harmony among statutory regulations.
