Greens Senator Sarah Hanson-Young is suing men's magazine Zoo over an article that depicted her as a bikini model in a photoshopped illustration.

The article, titled Zoo's Asylum Seeker Bikini Plan, appeared in the online version of Zoo Weekly in July last year.

The magazine offered to house the next boatload of asylum seekers in its office if Senator Hanson-Young agreed to a bikini shoot.

The senator is suing publisher Bauer Media, saying the article suggested she is not a politician to be taken seriously and that her pro-asylum seeker stance is ridiculous.

The publisher today succeeded in having those arguments struck out.

Justice Lucy McCallum also disallowed claims that the piece suggested Senator Hanson-Young was too emotional and immature to make a serious contribution on asylum seekers.

Justice McCallum did find the article is capable of having defamed Senator Hanson-Young, but said this is ultimately a question for a jury.
