Let's go over the first lot of questions from the most recent session to see!
"What actions he is taking to restore business confidence and the Island’s reputation following the Panorama programme and other media coverage?" Shimmins - Fair question, worded poorly.
"Whether the Isle of Man Government Brussels Office has reported on the impact of the European Parliament’s investigation into the action plan for a single EU VAT area and any changes to VAT which may come into force prior to Brexit; and if he will make a statement?" Edge - Fair question, even though you know the answer is "no, it's a pointless office"
"What plans he has to simplify the process for claiming free TV licences by those aged 75 and over?" Ashford - Fair question, worded poorly
"How much Manx Radio has invested in Radio Visualisation camera technology, the anticipated staffing and operating costs; and how it plans to develop this in future?" Caine - Bullshit question
"Whether the data in the Cabinet Office report on National Income 2015/16 [GD No 2017/0057] refer to calendar years or tax years?" Moorhouse - Idiotic question - It's something you ask in an email or phone call, not Tynwald. I hadn't quite realised what a dumbass this guy was.
And reading through the rest, except for Moorhouse and Caine throughout, and a couple that could be answered by a google search (presumably being asked to try and embarrass the minister in charge of that department to score 'points'), the questions seemed relevant and can lead to a change in the way things are done.
Remember, many of these questions are simply things the MHKs want official answers for, so they can reply to their constituents with honest answers.
The most recent one in my mind that has something changing in a major way just because of the questions being asked is the questions brought about the MER and it's braking system, and the subsequent release of the information that says the system is actually unsafe as balls, and suspended.
