Slater and Gordon law firm just won a case in which the federal government had to pay $70 million in compensation for those wrongfully held up by the immigration. Coming back to DIBP retrospective decision on 457 visa's pathway to PR, it is the immigration department who earlier prescribed that 457 visa holders are eligible to permanent residency under TRT stream. Observing this policy, thousands have sold their properties, changed their jobs and started a new path in Australia in a lawful manner. Indeed, they have made great contributions to this beautiful country. All of a sudden, the immigration minister issued a highly retrospective statement which deprived current 457 visa holders of their pathway to permanent residency. This retrospective statement shattered thousands of careers and damaged thousands of Australian businesses. In nature, this retrospective statement is contrary to all rule of law principles. I wonder if anyone has thought of a class action against such a retrospective statement.
