The Wiley balancing exercise has been applied for many years, and there is a rich history of precedent. The Minister plucks from the air “fair and effective”, but that was plucked from the air at the eleventh hour, at the last minute that an amendment could be tabled in Committee. What we, the Joint Committee, the special advocates and the House of Lords are saying is that if there is to be a gateway test before the decision about whether a hearing should be open or under a CMP, or about which material within a CMP should be open or closed, the judge should carry out a balancing exercise. He should weigh the public
interest in having an open and fair hearing against the harm done by the revealing of information that would breach national security. That is the test that judges use now and what the Supreme Court judges in al-Rawi would like to have used had they had the option of a CMP, which this Bill would give them.
