5. In 2019 a member of the New South Wales Parliament draws the attention of the Government to the fact that a certain bookseller, X, is selling obscene books, frequently to school children. The Attorney-General in answer to this states that he feels the bookseller should be punished and the legislation to deal with the problem will be prepared. Later in the year the following Act is passed:

An Act to regulate the Sale of Obscene and Indecent Books.

Whereas it is desirable that young and impressionable persons should be prevented from purchasing obscene and indecent books be it enacted that:-

1. No person shall sell or have in his possession any obscene or indecent book, pamphlet, picture or other work.

2. Any person convicted of selling or having in his possession any such work shall be liable to a penalty of a fine not exceeding $500 or imprisonment for 6 months or a fine not exceeding $100 or imprisonment of 10 days.

3. In any prosecution under the preceding sections if the magistrate hearing the case is satisfied that the work giving rise to the prosecution is obscene then whether he decides that the person accused is guilty of an offence or not, he shall order the confiscation of the work.

Consider the application of this Act to the following cases:

1. X, the bookseller whose activities led to the passing of the Act, is prosecuted in respect of a sale which took place before the Act was passed. She is also prosecuted in respect of her possession of another book after the Act became law. Both these books are obscene and the magistrate convicts X on both counts, imposing a fine of $250 in respect of each offence.

X appeals against her conviction in the first case and against the sentence passed in the second case. Should she succeed?
