Land purchase transactions in Indonesia, which often involve customary practices and are governed by law, require a written agreement, such as a Sale and Purchase Agreement (PPJB), to prevent conflicts. The PPJB binds both parties and is subject to civil law. In case of a breach of contract, the agreement may be canceled through the court. A breach of contract accompanied by fraud can result in criminal liability, and the affected party may file a civil lawsuit to annul the transaction. This study aims to (1) examine the legal consequences for the parties following the cancellation of a sale and purchase agreement for land rights by the court due to breach of contract; and (2) explore the legal protection available in the cancellation of such agreements in Indonesia. The research method employs a normative legal approach with a literature review, analyzing relevant laws, theories, and court decisions through primary and secondary legal materials. The analysis is qualitative, linking court decisions to the issues addressed in the study. The findings indicate that, in contract law, particularly in land sales, certain principles and conditions govern the validity of agreements. In the event of a breach of contract, the injured party may seek to annul the agreement in court if subjective (agreement, capacity) or objective (valid object and cause) requirements are not met. Cancellation of the agreement restores the parties to their original positions, allowing for the return of any goods exchanged. A breach of contract, where one party fails to fulfill its obligations, may lead to cancellation and compensation. Contract law provides legal protection to the injured party, including the right to demand performance, annulment, and compensation as outlined in the Civil Code.

The Constitutional Court (MK) Decision Number 90/PUU-XXI/2023 has attracted attention in Indonesian legal studies because it is related to the constitutionality test of the 1945 Constitution of the Republic of Indonesia (UUD 1945). The validity of this Constitutional Court Decision, when analyzed through the lens of legal realism, can be understood as the result of a compromise between the law as a norm that must be obeyed and the changing needs of society. Social factors, such as pressure from community groups or public opinion, play a significant role in influencing the Constitutional Court's decision. In this case, the Constitutional Court is tasked with interpreting the constitution in a broader context, which includes responses to socio-political dynamics and developing community aspirations. The legal realism perspective provides an understanding that the validity of the Constitutional Court Decision Number 90/PUU-XXI/2023 does not only depend on the text of the constitution, but is also influenced by developing socio-political dynamics. The Constitutional Court's decision reflects the interaction between legal norms and existing social conditions, with the Constitutional Court functioning as an institution that responds to social demands.

The development of digitalization has brought significant changes in various aspects of life, including employment relations. One of the innovations that has emerged is the use of digital employment contracts as a replacement for paper-based contracts. Digital employment contracts offer flexibility and efficiency in modern employment relations. However, in Indonesia, legal regulations related to digital employment contracts still face major challenges, considering the absence of regulations that specifically accommodate this mechanism. Article 52 of Law No. 13 of 2003 concerning Manpower only regulates the requirements for the validity of an employment contract without mentioning the use of electronic documents, while Law No. 11 of 2008 concerning Information and Electronic Transactions (UU ITE) has recognized the validity of electronic documents. This study aims to analyze the regulation of digital employment contracts in Indonesia, compare them with regulations in other countries, and provide policy recommendations to ensure legal protection for workers in the digitalization era. The method used is a normative legal approach with comparative legal analysis of countries such as the European Union and the United States. The results of the study show that although digital employment contracts are legally valid in Indonesia, there are still legal gaps related to the protection of workers' rights, supervision of implementation, and protection of personal data. Therefore, it is necessary to update regulations that are adaptive to technological developments, including the integration of the principles of justice, legal certainty, and protection of workers' rights in digital employment contracts.

The low reasoning ability of students in processing information has an impact on learning outcomes and creative thinking skills.
