In my experience it's not typical drafting practice for legislation to say that things don't operate retrospectively, because it's unusual for legislation to operate retrospectively. That's why, on occasion, you see legislation say it is going to operate retrospectively. If it doesn't say that, it operates prospectively. That's the case in all legislation that we consider.
