Question Hour is the first hour of a sitting session of the Lok Sabha devoted to questions that Members of Parliament raise about any aspect of administrative activity. The concerned Minister is obliged to answer to the Parliament, either orally or in writing, depending on the type of question raised. Questions are one of the ways Parliament can hold the Executive accountable.It is very useful for the Government.^[1]

There are four types of question—Starred, non-starred, short notice question and questions to private members.

1) Starred Questions are those for which an oral answer is expected. The member is allowed to as after the reply is obtained from the Minister concerned. Answer to such question may be followed by supplementary questions by member.

These questions are printed in green colour and are marked with asterisk sign '*', in order to distinguish from other questions.

2) Non-starred questions are those for which a written reply is expected. After the reply has been provided, no supplementary question can be asked. A notice period is to be given to the minister to reply to a question.

These questions are printed in white colour and not more than 230 questions can be listed for a day in the Lok Sabha.

3) Short notice questions are those which are asked on matters of urgent public importance and thus, can be asked on a shorter notice i.e. less than 10 days. These questions can be answered orally and supplementary questions can be asked.

These questions are printed in light pink colour.

4) Questions to private members are those which are asked to members who are not ministers. These questions are related to private member's bills, parliamentary committees, private member resolutions.

These questions are printed in Yellow colour.

However, if a Member seeks to ask a question urgently and cannot wait for the duration of the notice period, then the member can do so provided it is accepted by the Speaker. Such questions are called supplementary questions.

The following procedural changes have been in force since the 5th session of the 15th Lok Sabha:^[2]

• A 15-day notice period is now to be given to the minister to respond to a question in Parliament (concept of minimum and maximum notice duration has been removed). The notice duration used to be a minimum of 10 days or maximum of 21 days.
• The Speaker now has the authority to direct answers to a starred question asked by a member in case of his or her absence on the day their name was called.
• A member is now required to make a statement in the House correcting the reply given by him or her earlier, irrespective of whether the reply given pertained to a starred or unstarred or a short notice question.
• The maximum questions, starred or unstarred, a member is now entitled to give is 10 per day.

This sort of a process where elected representatives ask questions that are replied by the Prime Minister or other government ministers is part of parliamentary tradition in many other countries. The Question Hour in the Indian Parliament is similar to the Prime Minister's Questions in the House of Commons of the United Kingdom, the First Minister's Questions in the Scottish Parliament and Senedd Cymru/Welsh Parliament, and the Question Period in the House of Commons of Canada.
