I couldn't pinpoint one in particular at this time. The statement is a broad one. Ethics is much broader than the matters that affect people, as members or as public office-holders. I would never investigate an issue about the ethics of abortion or something like that. It has nothing to do with where we are. And as I also said, ethics does underpin the majority of the provisions of the act.
But on the spot, I couldn't name an ethical issue that I want to be able to investigate, although as I look at issues I may make comments as I go along. But nothing comes to my mind right now.
