9. The Ombudsman filed an information against City Mayor Isidro for violation of Section 3(e) of Republic Act No. 3019 or the Anti-Graft and Corrupt Practices Act before the Sandiganbayan. The information alleged that Mayor Isidro, “an incumbent City Mayor with Salary Grade 30, while in the performance of his official and administrative functions, acting with evident bad faith and manifest partiality, did then and there willfully, unlawfully and criminally give unwarranted benefits to ABC Corporation by allowing it to operate a dumpsite without the necessary environmental permits and clearances causing undue injury to the residents who had to endure the stench, flies, rats and mosquitoes emanating from the dumpsite.” Mayor Isidro sought to dismiss the criminal case for lack of jurisdiction and explained that the Regional Trial Court (RTC), not the Sandiganbayan, has authority to decide the controversy. Which between the Sandiganbayan and the RTC has proper jurisdiction over the criminal case? Explain.
