The question about action against illegal gravel mining, asked by ruling party MLA Prahlad Gunjan, was part of a list of questions.
When it was the time to take up the question, Speaker Kailash Meghwal said that it had been suspended and would be answered later.
The Congress members then created an uproar, saying the government did not want to answer an important question and also boycotted the Question Hour.
Parliamentary Affairs Minister Rajendra Rathore said the government was willing to answer. He requested the speaker to include the question on the day when questions for the mines department would be taken up.
