The Lokpal and Lokayuktas Act, 2013, defines the jurisdiction and powers of the Lokpal. Chapter VII specifically addresses the 'Powers and Procedures' available to the Lokpal during inquiries and investigations.
The question asks to identify the power that is explicitly not granted to the Lokpal under Chapter VII of the Act.
The Lokpal, while having significant investigative and recommendatory powers, does not possess the full judicial authority of a criminal court. The Act does not grant the Lokpal the power to function directly as a criminal court, adjudicate criminal trials, or impose punishments in the same manner as a criminal court does.
Therefore, the specific power mentioned, 'Powers of criminal court in certain cases', is not vested with the Lokpal under Chapter VII of the Act, 2013.
