By one means or another, Colin Craig has succeeded in keeping his Conservative Party in the public eye over the past few years. Doing so without the advantages of parliamentary representation has required some degree of political nous.
Mr Craig's reward has been the increasing potential for the Conservatives to be a serviceable ally of the National Party after the general election. This week, he has captured attention again by saying he will take a defamation case against Greens co-leader Russel Norman. A favourable interpretation would be that this is yet another publicity ploy. Unfortunately, it smacks far more of a naivety totally at odds with the rough and tumble of politics.
Mr Craig has called on Dr Norman to apologise by tomorrow for saying that he "thinks that a woman's place is in the kitchen and a gay man's place is in the closet". If not, he will seek a declaration under the Defamation Act that the statement was false and offensive. Dr Norman has made it clear that he has no intention of apologising.
There is no reason he should. Political leaders more seasoned than Mr Craig are used to robust criticism, particularly as elections loom. They do not seek refuge in the law because they know they have ready access to the media and can respond to criticism equally fiercely. Indeed, such exchanges can be expected to be part and parcel of any election campaign when polar opposites such as the Greens and the Conservatives clash.
As much was underlined by the Court of Appeal's ruling in the case of Lange v Atkinson that the normal rules of defamation do not apply when a politician is criticised. A different standard of discourse and language is acceptable. A proviso is that defamatory statements about politicians could lose their qualified privilege if those who hold the opinion are "unable or unwilling to disclose any responsible basis for asserting a genuine belief". That is unlikely to trouble Dr Norman.
