A bold move by the Abbott government to circumvent a decision of the High Court and the will of the Senate appears certain to trigger another High Court challenge.

Immigration Minister Scott Morrison has responded to a court decision two weeks ago on visa caps by declaring he will personally apply a "national interest" test to every application for permanent protection by those who arrive without a visa.

The minister has also signalled he will reject all such cases by outlining several reasons why the national interest test will deny the grant of permanent visas and no reasons that would support the grant of a permanent visa.

He has also announced that his decisions to deny visas in "the national interest" cannot be reviewed by the Refugee Review Tribunal.
