Well, of course it depends, given that it changed about a dozen laws in dozens of ways, on which particular law you're talking about. Overall, the Accountability Act took 29 steps forward in terms of changing the ethics rules, political donations rules, access to information, whistle-blower protection, but there were also seven steps backwards, mainly in terms of the Conflict of Interest Act and rules being removed from it that existed in the old conflict of interest code.
In total, it's a net positive of 22 changes in terms of accountability, but as I mentioned, there are many, many loopholes still open: enforcement problems that mean questionable situations can arise and the questions really can't be resolved in terms of accountability and responsibility.
