I think it is more a chance to show that they were not the only ones who had people who were not eligible but they were the only ones who were honest about it. Labor should have come clean a little better than they have.
For that matter why can’t we just have everyone checked, and if more are found, dissolve parliament and start again? This time actually have someone check each candidate to ensure they are not breaching the laws. Don’t we have some sort of electoral commission to make sure candidates are allowed to run? Surely that would be part of the process in a multicultural society?
