Australia's Federal Government is playing down the significance of the High Court ruling that found a Sri Lankan refugee could not be denied a visa, despite being deemed a security risk.
The ruling could have implications for more than 50 other refugees who have adverse security assessments and are under indefinite detention.
The High Court said it was invalid to use an adverse security assessment from ASIO to prevent a 36-year-old Tamil man from Sri Lanka being granted a protection visa.
The majority of the court ruled that the regulation which allows ASIO rulings to be used in that way is inconsistent with the Migration Act.
But the Government says the decision does not undermine its approach to asylum seekers.
Attorney-General Nicola Roxon is currently assessing the ruling, with Labor calling on the Opposition to support possible legislative changes to Australia's migration laws.
