Article 186 clarifies the legal procedure for prosecuting tax crimes. Public actions (criminal lawsuits) for offenses mentioned in this Chapter can only be initiated upon a formal request from the Chairman of the Tax Authority. The Authority must coordinate with the Public Prosecution for these filings. Critically, once a request to file a public action is submitted, it cannot be withdrawn or relinquished. This provision centralizes the control of tax-related criminal litigation with the Chairman, ensuring that prosecution is used strategically as an enforcement tool for the most serious cases.
