Speaker Abdul Hamid said TIB should come up with accurate information.
'They (TIB) should think carefully before disclosing any information. Everybody should be sincere so that nation is not misled for wrong information,' the speaker said.
Hamid questioned TIB's jurisdiction to prepare the report, released Saturday. He also asked how TIB collected the information since they did not come to him.
He, however, admitted that the house sittings begin seven to 12 minutes behind the scheduled time.
'I attended many roundtable discussions organised by civil society (bodies) that started even 45 minutes late. Compared to them parliament is in a better position,' the speaker said.
The perceived wastage of funds is notional and takes place in legislatures across the world, analysts said.
