The issue of the sub judice limitations on our committee and respect for the courts is a fundamental parliamentary procedure. It has been ruled upon time and time again that:
It is accepted practice that, in the interests of justice and fair play, certain restrictions should be placed on the freedom of Members of Parliament to make reference in the course of debate to matters awaiting judicial decisions, and that such matters should not be the subject of motions or questions in the House.
This is ultimately a decision that is referred to the Speaker. Furthermore:
The acceptance of a restriction is a voluntary restraint on the part of the House to protect an accused person or other party to a court action or judicial inquiry from suffering any prejudicial effect from public discussion of the issue.
