Peak anti-smoking bodies say tobacco giants are simply huffing and puffing with claims a plain packaging law could be unlawful or unconstitutional.
Plain packaging is among measures in the as-yet-unreleased Preventative Health Taskforce report, along with a tax rise and bans on sponsorship, internet sales, corporate responsibility donations and public relations drives.
Health Minister Nicola Roxon received the report last Wednesday and is considering its proposals, which include a tax rise taking the price of a pack of 30 cigarettes to more than $20.
Lobby group Quit yesterday supported the proposed changes. Policy manager Kylie Lindorff said suggestions from giants British American Tobacco and Phillip Morris that packaging laws could be unlawful were unfounded.
''Lawyers from our group have looked at that,'' she said.
''We don't believe there are any challenges they could mount in Australia.''
The proposed regulations reportedly recommended a generic packet with larger health warnings covering 90 per cent of the front and all of the back.
