Mr Mandrekar made the remark today during a debate on civil supplies in the ongoing budget session of the state legislative assembly.
"Sometimes officials do not do any work properly and do not listen too. Then like he (Mickky Pacheco) said, they should be slapped," Mr Mandrekar said.
Goa Vikas Party legislator Mickky Pacheco had, earlier during the debate, said that officials of the water resources department had been ignoring the building of a retaining wall in the village of Betalbatim, 30 kms from Panaji, and that there was no way that they could be made to work unless people slapped them.
Mr Pacheco has already been convicted for slapping a government official on duty. He has appealed against the sentence.
