469. Interpretation: when does a tariff scheme apply or not apply to a case

For the purposes of this Division, a tariff scheme (being a scheme that is in force) is taken —

subject to paragraph (b), as applying to a case if permission would be granted in that case under the terms of the tariff scheme; and

as not applying to a case if —

the permission granted would be subject to exceptions; and

the case falls within one or more of those exceptions.
