Certainly, that is definitely worth looking at.
Part of the challenge under this legislation is that it captures so many different public office holders. There are very different concerns in being a minister of the crown, in being a staffer in that minister's office, and in being a public office holder somewhere else in government. Concerns about influencing government or appearing to improperly influence government may differ depending on the circumstances.
If somebody has their first job out of university, working for six or eight months in a minister's office at a low level, I don't think there are concerns about potential conflict of interest if they leave government and work for a private sector firm that ends up lobbying another area of government. Those concerns are not the same as a minister of the crown or the head of a public agency leaving and then going back and lobbying government.
You have to look at some of the different concerns.
