Unlike the Parliamentary system, the concept of 'question hour' or 'question time' doesn't really exist in the American legislature. Here's an interesting report done by the Congressional Research Service on the possibility of a question time in the US. From our point of view, the report is interesting because it reviews the existing provisions for a Parliamentary Question Time in different countries (India isn't mentioned), and considers the pros and cons of such a system. The report concludes: "Whether the question period would be successful in a system of separated powers depends in large part on the attitude of its participants and on the format the question period ultimately assumes. The question period has the potential of involving more rank-and-file Members in the policy-making process, and improving the means of communication between executive departments and the Congress. It also could harden relations between the Congress and the Executive, and might increase the level of partisan controversy in Congress." There's even an online petition among a few american bloggers to push for a question time in the US. Read about it here. In this country of course, parliamentary questions are an established feature of the work of Parliament. Parliamentary questions cover a huge range of topics and can be an mine of information and data about government policy. The Lok Sabha and Rajya Sabha sites put the complete text of all parliamentary questions (and the responses to them) online.
It is common knowledge that individuals contesting elections have to file an affidavit, declaring (i) their criminal records (if any), (ii) assets & liabilities and (iii) educational qualification. What is not widely known is that after getting elected, Members of Parliament are required to file a declaration of assets and liabilities with the Speaker of Lok Sabha and the Chairman of Rajya Sabha. The rules to this effect were made in 2004 under the Representation of Peoples Act , 1951. These declarations have to be made by MPs within 90 days of taking their seat in Parliament. Rules for Lok Sabha MPs an be found hereand those for Rajya Sabha MPs can be found here. The Rajya Sabha rules specify that the declarations made by MPs shall be made availaible to any person with the written permission of the Chairman. The rules also specify that Rajya Sabha MPs are required to update their declarations every year. The Lok Sabha rules specify that the declarations made by the Lok Sabha MPs shall be treated as confidential and shall not be made available to any person without the written permission of the Speaker. The rules also do not contain an express provision for the declaration made by the MPs to be updated in case there is a change in the status of their assets and liabilities. Such rules under the Representation of Peoples Act currently do not exist for MLAs in States.
