When one of his ministers appears to have run foul of the Cabinet Manual, John Key is prone to defending the culprit on the grounds that the 160-page handbook is only a guide, rather than a set of hard-and-fast rules decreeing what is acceptable and unacceptable in terms of ministerial behaviour.
The Prime Minister is right in part. If the breach in standards is really obvious and really serious, then no one needs recourse to the manual to work out what needs to be done. But Key is also in the wrong. If the Cabinet Manual is only a guide, then Simon Bridges, his Transport Minister, is way off the beaten track.
The manual is absolutely clear about the rules which should apply between a Cabinet minister and public servants prior to a byelection. In defending Bridges, Key is devaluing those principles.
Which ever way you look at those rules, it is impossible to avoid the conclusion that Bridges breached restrictions on the use of information obtained from officials in the pre-election period.
Bridges is adamant he was not in breach; that he sought information about one-lane bridges in the Far North. He did not seek advice from those officials.
