Essentially there had been a procedural error into the coming into force of this agreement. The agreement, by law, needs to be tabled in both houses of Parliament. Due to a departmental procedural error it was tabled only in the House and not in the Senate.
This is an effort to ensure that both houses of Parliament have an opportunity to review the agreement and to ensure that people who would be entitled to benefits, as of when the agreement was supposed to have come into force, will be entitled to their full benefits.
