In Zero hour & Short Notice question hour. In both the question hours Matter of Public Importance asked. So based upon of whihc critearia it is decided & who decided the question falles in to Zero hour or Short Notice question hour. To me it looks like both the question hours are same. Please put your comments

First of all, there is only one Question Hour, between 11 to 12. All the questions including Short notice questions are asked in Question Hour. In Zero Hour any matter can be raised impromptu, whereas Short notice questions are asked with Speaker's permission. When short notice questions asked it is imperative that minister to whom these questions are asked remain present, whereas during Zero Hour it is not necessary that minister will remain present because nobody knows what matter would be raised. For more details read my reply to Tushar Gupta.
