This study examines the limitations of judicial reasoning in the evidentiary assessment of a breach of contract dispute involving an online loan agreement in Judgment Number 267/Pdt.G/2020/PN.Bdg. The case arose from a claim brought by PT Satustop Finansial Solusi, as the operator of a peer-to-peer lending platform, together with individual lenders, against a borrower who failed to fulfill the repayment obligations under the loan agreement. The central issue concerns the court’s reasoning, which failed to adequately articulate the legal relationship between the platform operator, the lenders, and the borrower, as well as the evidentiary status of the investment history data and loan statements as electronic evidence. However, the facts established at trial, together with the supporting evidence, including the investment history data, digital transfer records, and the platform’s operational mechanism, clearly indicate the characteristics of an information technology-based transaction. This study critiques the evidentiary process at trial, which continues to rely on conventional documentary evidence without making full use of the electronic discovery (e-discovery) framework to verify metadata, digital traces, and the integrity of electronic data, as mandated by the Electronic Information and Transactions Law and the Financial Services Authority regulations. The findings indicate that the panel of judges’ reasoning was sufficient to conclude that a breach of contract had occurred because the defendant admitted the existence of the principal debt, interest, and penalties and failed to fulfill the repayment obligations. Such admission was corroborated by the loan agreement, transfer records, warning letters, and demand letters. The panel of judges also failed to explain the evidentiary status and probative value of exhibit P-8, consisting of investment history data, and exhibit P-9, consisting of loan statements, as electronic information and/or electronic documents. These limitations do not undermine the evidentiary basis for establishing a breach of contract, but the legal reasoning in the judgment does not fully reflect the characteristics of information technology-based peer-to-peer lending transactions.
