Senator WRIGHT (South Australia) (14:41): Mr President, I ask a supplementary question. The Abbott government's original plan gave the immigration minister sole power to revoke citizenship of dual nationals. Instead, the current bill makes loss of citizenship essentially a bureaucratic decision and gives the immigration minister the sole power to overturn that decision in a process in which the rules of natural justice do not apply. Is the Attorney-General able to deliver a tortuous explanation of how these two plans differ?
