(c)     uses it; or

(d)     has it output from the computer in which it is held, whether by having it displayed or in any other manner,

and references to access to a program or data and to an intent to secure such access shall be read accordingly.

(3)    For the purposes of paragraph (2)(c) a person uses a program if the function the person causes the computer to perform –

(a)     causes the program to be executed; or

(b)     is itself a function of the program.

(4)    For the purposes of paragraph (2)(d) –

(a)     a program is output if the instructions of which it consists are output; and

(b)     the form in which any such instructions or any other data is output and in particular whether or not it represents a form in which, in the case of instructions, they are capable of being executed or, in the case of data, it is capable of being processed by a computer is immaterial.

(5)    Access of any kind by any person to any program or data held in a computer is unauthorized if –

(a)     the person is not entitled to control access of the kind in question to the program or data; and

(b)     the person does not have consent to access of the kind in question to the program or data from any person who is so entitled.

(6)    References to any program or data held in a computer include references to any program or data held in any removable storage medium which is for the time being in the computer; and a computer is to be regarded as containing any program or data held in any such medium.

(a)     any program or data held in the computer concerned is altered or erased; or

(b)     any program or data is added to its contents,

and any act which contributes towards causing such a modification shall be regarded as causing it.

(4)    Subject to Article 10, where –

(a)     any such link does in fact exist in the case of an offence under Article 2; and

(b)     commission of that offence is alleged in proceedings for an offence under Article 4,

Article 4 shall apply as if anything the accused intended to do or facilitate in any place outside Jersey which would constitute a further offence under Article 4 if it took place in Jersey were the offence in question.

7      Significant links with jurisdiction of Jersey

(a)     conspiracy to commit an offence under this Law;

(b)     attempting to commit an offence under Article 5; or

(c)     incitement to commit an offence under this Law,

but for the fact that what the person agreed to do, attempted to do or, had in view, as the case may be, would not be an offence triable in Jersey –

(i)     what the person agreed to do, attempted to do or, had in view, as the case may be, shall be treated as an offence under this Law for the purposes of any charge of conspiracy, attempt to commit an offence or incitement, as the case may be, brought in respect of that act; and

(ii)    any such charge shall accordingly be triable in Jersey.

10    Relevance of external law

(2)    A person shall be guilty of an offence triable by virtue of Article 9 only if –

(a)     an act or omission by one or more persons; or

would constitute an offence under the law in force where the act, omission or other event was intended to take place.

(a)     Article 9(b) only if what the person attempted to do;

would involve the commission of an offence under the law in force where the whole or any part of it was intended to take place.

(4)    Conduct punishable under the law in force in any place is an offence under that law for the purposes of this Article, however it is described in that law.

11    British citizenship immaterial
