"In an order, Chief Secretary Mohan Verghese Chunkath has stated that it would suffice if probe was carried out in Madurai district," Ramadoss said in a statement here.
This alleged step of the government would defeat the very purpose for which the Madras High Court had appointed IAS officer U Sagayam to probe the illegal granite quarrying, he alleged.
"The Tamil Nadu government should extend the probe so as to unearth the illegalities in mining across the state."
