The evidence of Mr. Smith was that there were still some loopholes in terms of specific questions that were not asked to every household, and it goes to an interpretation by the court that could be made. So I agree with you that on the reading of that section, one would think that every question goes to households and that all questions all mandatory, but the court had, in the 2011 case, said that questions are mandatory if they're part of the census, but to be part of the census they have to go to all households. The issue was that if you are asking specific questions that don't go to all households, are the sections with those particular questions not considered under the rubric of the general statement that you have to answer all questions on the census. It's not whether answering questions on the census is mandatory; it's whether questions that go to only some households are considered part of the general census.
