As you'll see, the intention behind 14, the next clause, is to clarify that those tax treatment agreements are not protected by the Constitution. They are simple side agreements to deal with the basic tax exemptions that we provide to other governments in this country. That is the scope of what these clauses consider.
It's true that there aren't added constraints on this section. There is a history of these kinds of negotiations. The Minister of Finance has a mandate to negotiate these, and there's a scope to that mandate. These really are specific to the tax exemptions of the government and the tax treatment of these governments.
