Justice P Ubaid declined the prayer by Anti-Corruption Human Rights Protection Committee of Palakkad and posted the matter for further hearing after a month.
"The investigation is in a preliminary stage. At this stage, the court cannot intrude in the process of investigation and monitor the case," the judge observed.
The scam pertains an allegation by a bar hotelier that hefty sum was paid to Mani for his help in reopening some of closed liqour bars in the state. Based on this, the government initially ordered a "quick verification' and later lodged an FIR for a detailed probe.
The judge, however, said the petitioner can approach the court citing specific ground or when it finds some wrong in the investigation. "Now there is no reason to interfere in the process of investigation."
He also asked the petitioner's counsel why it has not arraigned Mani as a respondent in the writ plea.
The court wanted the petitioner to address it regarding the scope and extent of powers under Article 226 of the Constitution to intrude in the process of investigation and monitor the case.
