He asked the members to refrain from doing saying it sent a wrong message.
Earlier, the House mourned the death of its former member R Margabandu on December 28, at the age of 83 years.
In the passing away of Margabandu, the country has lost a distinguished parliamentarian and a noted lawyer, Naidu said in his obituary reference.
