Which of the following proceedings is NOT barred by Section 28 of the Prevention of Corruption Act, 1988?

Section 28 makes the Act additional to, and not in derogation of, any other law for the time being in force, and provides that nothing in it exempts a public servant from any proceeding that might, apart from the Act, be instituted against him. A criminal case under the Bharatiya Nyaya Sanhita, 2023 (formerly the Indian Penal Code, 1860), departmental disciplinary action and civil recovery therefore all remain unbarred.
