If I may say so, that's exactly the principle. It basically goes back to the Financial Administration Act. Under section 32, we commit toward certain work, and under section 34, we have to receive confirmation that the work is done, by receipts and other proof. There, it is section 34 that applies. This is the Financial Administration Act, or the guts of it.
