The concept Mr Bouchier had in mind requires ministers to exercise judgment before commenting on judicial decisions, whether generally, or in relation to the specifics of an individual case.
This principle is codified in the Cabinet Manual. The document, which guides the conduct of the Executive, says ministers "should not express any views that are likely to be publicised if these views could be regarded as reflecting adversely on the impartiality, personal views, or ability of any judge". The manual includes the advice that ministers "should avoid at all times any comment that could be construed as being intended to influence the courts in subsequent cases".
Ms Collins' remarks could, at a stretch, be seen to skate close to these clear warnings. It is clear, however, they were couched in a way that accepted judges were the right people to make bail decisions because they had the appropriate information in front of them.
New Zealand needs robust ministers who speak their minds. Ms Collins is one of them. It is a habit which in the past has got her in trouble. But it is hard to see how her bail remarks in this case would harm the judiciary as a whole or the judge who made the decision.
Mr Bouchier suggested the Attorney-General, who manages the relationship between ministers and the courts, have a word with the Corrections Minister. It is entirely possible that such an intervention will one day be required with the bluff Ms Collins. In the matter of the absconding defendant, it is unwarranted.
