The sting operation spanned nearly eight months from April 2005 to December 2005. During this period, 10 Lok Sabha members and one Rajya Sabha MP were caught on camera accepting money from representatives of the fictitious body North India Small Manufacturer's Association (NISMA) for asking questions parliament.

In all, more than 60 questions were submitted by 11 MPs. Of these, 25 questions were tabled in parliament.

Hearing the submissions, the court issued notice to Delhi police and asked it to file their reply as to why Bahal has been made a party into the case.

The court also granted Bahal exemption from personal appearance.
