"1. The applicant's conviction is in law a nullity as the Western Australian Police Service had no jurisdiction to arrest and charge the applicant for an offence known to have been committed on board an aircraft in flight contrary to s 10(1) of the Crimes (Traffic In Narcotics and Psychotropic Substances) Act 1990 (Cth); and
2. Further, or alternatively, the applicant was arrested at a 'Commonwealth Place' as defined by s 4 of the Commonwealth Places (Application of Laws) Act 1970 (Cth), as a result the District Court of Western Australia was required to sit as a State Court vested with federal jurisdiction, which it did not, the application's conviction is therefore in law a nullity; and
3. Further, or alternatively, the applicant's conviction is in law a nullity as there was no jurisdiction under the Misuse of Drugs Act 1981 (WA) for the State of Western Australia to prosecute an offence as if it were a State offence, when any offence occurred on board an aircraft in flight, contrary to s 10 of the Crimes (Traffic in Narcotics and Psychotropic Substances) Act 1990 (Cth), that is an offence against a law of the Commonwealth, and that Commonwealth law therefore takes precedence; and
4. Further, or alternatively, there is no power for the Federal Parliament to delegate the judicial power of the Commonwealth to a State to enforce laws in a place that is subject to the exclusive jurisdiction of the Commonwealth by operation of s 52(1) of the Constitution of the Commonwealth of Australia; and
5. Further, or alternatively, s 4 of the Commonwealth Places (Application of Laws) Act 1970 (Cth) offends s 52(1) of the Constitution of the Commonwealth of Australia and is invalid; and
6. Further, to the extent that there is any inconsistency between the Crimes (Traffic In Narcotics and Psychotropic Substances) Act 1990 (Cth) and the Misuse of Drugs Act 1981 (WA), the Misuse of Drugs Act 1981 (WA) is rendered invalid to the extent of the inconsistency by operation of s 109 of the Constitution of the Commonwealth of Australia; and
7. Further, the Australian Federal Police have exclusive jurisdiction to arrest and detain an offender at a Commonwealth place pursuant to s 8 of the Australian Federal Police Act 1979 (Cth), the Western Australian Police Service were therefore acting out of their jurisdiction, the applicant's arrest and the seizure of the prohibited substance was therefore unlawful."
