It held that, given the seriousness of allegations involving public funds, an independent and comprehensive probe was necessary to ensure justice..The order was passed on a public interest litigation petition filed by NGO Arappor Iyakkam..The petition concerned ten tenders floated between 2021 and 2023 for the purchase of approximately 45,800 distribution transformers, with a total estimated value of ₹1,183 crore. Arappor Iyakkam claimed that the tendering process was manipulated to favour select bidders, resulting in an alleged loss of around ₹397 crore to the State exchequer..A key plank of the challenge was the allegation of identical price bidding across multiple tenders. According to the petitioner, in at least seven tenders, between 25 and 37 bidders quoted the same prices, a pattern said to be indicative of cartelisation and in violation of the Tamil Nadu Transparency in Tenders Act.Despite this, the contracts were not cancelled and were instead awarded, the plea statedThe petition also pointed to instances of inflated pricing, including the procurement of a 500 kVA transformer at around ₹12.49 lakh against an alleged base value of approximately ₹7.89 lakh. On this basis, the NGO sought a court-monitored investigation, including the constitution of a Special Investigation Team and registration of a criminal case. It contended that no FIR was acted upon despite complaints..The petitioners were represented by Senior Advocate V Raghavachari with Advocates V Suresh, and AG Vedavikas..The State was represented by Advocate General PS Raman and Additional Advocate General P.
