If you accept my recommendations—for example, having targets that have to meet those SMART criteria—then there's actually two mechanisms that could take place.
One is that the commissioner could be empowered to say, “These targets do not meet the criteria; there's no measurability here. I won't be able to actually measure progress towards achieving the target.” My recommendation is that if the commissioner says that, then the strategy itself should go back to the government to be revised until it meets with the commissioner's approval. Basically, it's giving her the power to approve the strategy.
Secondly, if the law requires measurable targets and the targets aren't measurable at the end of the day, then you could have citizens holding the government to account for failing to comply with the mandatory requirements of the law.
