There are far more substantive differences in the editions of 2006 and 2007, in that 2006 predates the Federal Accountability Act. The 2006 edition was issued by the Prime Minister upon coming into office in February.
The 2007 edition is post the passing of the Federal Accountability Act so it contains sections dealing with the role of deputy ministers as accounting officers. It contains annexes G and H, which were not there before, ethical conduct and the political activity guidelines. Ethical conduct used to be in a code, and when the Conflict of Interest Act was brought into force through the Federal Accountability Act, the ethical portions were put into annex G.
There is usually some cleanup of language going on. We're continually parsing language.
Those would be the major changes. Certainly annex H is a change in the sense that it did not exist in that form prior to 2007.
