"I demand a high-level inquiry by an independent body like Crime Branch or CBI into the matter," former Minister and Congress MLA from Doda constituency Abdul Majid Wani said in a statement.
A wall of the historic Assembly complex collapsed on December 10 due to digging work taking place close to the complex for construction of new Legislative complex in Jammu.
He accused the Jammu and Kashmir Project Construction Corporation (JKPCC) of shelving off and delaying completion of important projects and showing high degree of delinquency in execution of other state projects.
The MLA has also requested Chief Minister Omar Abdullah to order performance audits of all ongoing engineering projects of JKPCC in the state.
JKPCC engineers and contractors could not take required precautions while digging, excessively, surface of the old complex for constructing the new complex, he said.
