However, in practice in the jurisdiction of the Tapaktuan District Court, judges do not impose criminal charges against recidivist criminal acts of theft in aggravating circumstances. This paper examines the Basic Considerations of Judges in Imposing Decisions on Recidivist Criminal Acts of Theft in Aggravating Circumstances and Factors Causing the Repeated Crime of Theft in Aggravating Circumstances. Based on the discussion above, it can be concluded that in the judge's decision it was not aggravating because the perpetrator regretted his actions and promised not to repeat it again, the perpetrator was also polite in court and the perpetrator was honest in giving information.
