Linguistic Features of the Crimes of Insult and Defamation in Indonesia's Criminal Justice System

Abstract

This study examines the linguistic features of insult and defamation offenses within Indonesia's criminal justice framework from a forensic linguistics perspective. With the rapid growth of digital communication, there has been an increase in criminal cases involving online speech. Accordingly, courts and law enforcement agencies are increasingly relying on objective linguistic evidence to distinguish protected expressions of opinion from defamatory statements that carry criminal liability. Recent scholarly work suggests that forensic linguistic analysis has become a vital evidentiary method in assessing alleged defamation, hate speech, and digital discourse in Indonesia.

This research adopts a qualitative descriptive methodology grounded in a forensic linguistic framework to scrutinize linguistic evidence derived from court rulings, police investigation reports, and digital communications related to alleged offenses of insult and defamation as defined under the Indonesian Criminal Code (KUHP) and the Electronic Information and Transactions (ITE) Law. The analysis focuses on lexical choices, speech acts, evaluative language, pragmatic implications, contextual interpretation, and discourse structure to understand how linguistic characteristics influence the legal assessment of criminal intent and reputational damage.

The results indicate that offenses of criminal insult and defamation are characterized not only by offensive lexical items but also by the interaction between semantic content, pragmatic intentions, contextual circumstances, audience interpretation, and evidential support. Speech acts conveying accusations, negative evaluations, and imputations of fact are more likely to meet the legal criteria for defamation when accompanied by demonstrable intent to harm an individual's reputation. Conversely, criticism, opinions, and value judgments, supported by contextual evidence, are less likely to be classified as criminal acts. Furthermore, the research demonstrates that forensic linguistic analysis enhances legal certainty by providing systematic and scientifically grounded methods for interpreting contentious language evidence.

This study contributes to the expanding field of forensic linguistics in Indonesia by integrating linguistic theory with criminal law analysis. It offers practical implications for investigators, prosecutors, judges, and linguistic expert witnesses by facilitating objective evaluation of language evidence, thereby fostering increased consistency, fairness, and transparency in adjudicating cases of insult and defamation within Indonesia's criminal justice system.
