To John's point, if members of Parliament are following the ball correctly, the only difference is that if this model was implemented, the committee of the day would say that they don't like the department transferring money within programs within this strategic outcome, so they're reducing based on, say it's supplementary (C)s or something.... They've done it in the past. You're always reacting. The committee would then say they were going to reduce the money being applied to this strategic outcome, and that would be reflected in the actual vote in the appropriations bill.
