Why only Canada's legislature? The parliamentary committee that summoned Zuckerberg and Sandberg represents more than just the Canadian Parliament. If one were to expand the conditions under which you feel this could be good "governance, policy, economics and ethics", you could find many cases of executive officers of publicly listed companies being summoned to testify before parliament. Philip Green comes to mind, but I'm sure there are many more - requesting testimony from corporate offices it not as unusual as you may think; I don't recall the names now, but I'm pretty sure I've seen the CEOs of some major American corporations in front of the House and Senate on numerous occasions, such as after the Great Financial Crisis. >the contents of that interrogation have led to substantially unanticipated outcomes How would one prove something like that? I think some more specificity would be necessary to be able to answer that question. Do you mean unanticipated by the mainstream of commentators, unanticipated by the legislature itself, by the corporate officer in question, by literally anyone on the Earth, or by yourself?
