I will answer that question.
On the recourse provisions that you're referring to, none of them were actually brought into force after Bill C-4 came into force. They were to come into force through an order in council that never actually happened.
The package of reforms that were in that section dealing with employer recourse made some changes that were meant to streamline some of the recourse processes. Take, for example, the one about taking away the right of employees to file human rights complaints in lieu of a grievance. Some saw that as taking away some fundamental human rights from employees, because the human rights act has different provisions from the labour relations act.
I can't say for certain why those were put into place before, but again, like the rest of the legislation, it will all be repealed by Bill C-62.
