That's a principle of statutory interpretation that's raised from time to time, expressio unius est exclusio alterius, which means that stating one thing means it's ruled out elsewhere. However, in statutory interpretation, to use that, you have to have a clear intention that Parliament intended it to be that way, intended that it would apply only when it was explicitly referenced. Ultimately, I'd look at the overall intention.
