Meghalaya Right to Information Movement, using RTI, had found fault with the state government and supplier last year regarding the supply of substandard Corrugated Galvanised Iron (CGI) sheets during the period between 2003 and 2006.
"The pilferage percentage under the scheme is a massive 52.12 per cent of the total Rs 19,34,81,221 spent in the purchase of CGI sheets," MRTIM convener Michael Syiem said.
"The public hearing is aimed at following up to the last public hearing held in May last year."
The second public hearing will be held November 24 in the city.
Based on the RTI findings, the MRTIM had complained to the government and demanded that the government initiate an independent inquiry into the scam.
The Chief Minister and the Housing Department had rejected the findings to which the MRTIM followed up with more RTI queries to substantiate their earlier claims.
The State Vigilance Commissioner and other government officers and Suppliers were invited to share their point of views at the public hearing.
