Sarmilis with Bilkisti and Sugeng Padmono. In this case, the plaintiff (Ir. Hj. Sarmilis) requires the defendant (Bilkisti and Sugeng Padmono) to return the money which is will be used to commit bribery. This study focuses on the consideration of the Supreme Court who judge the case in the Supreme Court of the Republic of Indonesia Number 3038 K/Pdt/2009 which granted the request of Plaintiff Appeal to return the money to him in their illicit agreement because of bribery can be justified or not. This study used a normative approach. Then analyzed by using a deductive method. Based on the results of the research, it was concluded that the petition of Cassation Plaintiff can not be granted because of the agreement between the plaintiff (Ir. Hj. Sarmilis) and the defendant (Bilkisti and Sugeng Padmono) does not fulfill the Article 1320 Civil Code about the validity of the agreement`s terms about permissible cause (objective conditions) because there are bribery`s elements inside based on Article 1335 and Article 1337 Civil Code itself is prohibited by law as those contained in Article 5 Legislation of the Republic of Indonesia Number 20/2001 on Amendments to the Legislation Number 31/1999 about Eradication of Corruption, so that the agreement is null and void, has never been considered, and the situation is back to the normal that the money is returned to the honoree employee and promised services do not need to be fulfilled.
