I know it was a decision for the Minister, but with respect to the Minister, who may prove me wrong, he is not an expert on autoclaved aerated concrete blocks or whatever else. He relies on the witnesses, as officials who have engaged with the Departments of Housing, Local Government and Heritage and the Environment, Climate and Communications, to make a recommendation to him. I do not think he sat down and decided what to go with at random. Did the witnesses give any consideration to including this type of block?
