16 MPs have been indicted over alleged bribery for breaches of both the Leadership Code and the Penal Code.
The MPs charged with bribery are mostly in government.
One of them, Finance Minister Willie Jimmy, pleaded guilty this week.
The Public Prosecutor's office says counsels representing some of the accused approached it recently seeking indemnity from prosecution under the Public Prosecutor Act.
After consideration in accordance with accepted procedures, no indemnity was granted to any of them.
