These loyalties exist largely because it is marketing and branding, more than anything else, which make an FMCG product distinctive.
This is why New Zealand has strong intellectual property laws (such as the Trade Marks Act 2002, the Fair Trading Act 1986, and the common law tort of passing-off). It is critical for businesses to protect the intangible assets they have gained over the years.
Cigarettes are not different from any other FMCG product in the sense that they are interchangeable and it is brand rather than actual product content that is the key differentiator. It is therefore unsurprising that the tobacco industry becomes nervous when the New Zealand Government starts talking about following Australia and introducing plain packaging of tobacco products this side of the Tasman.
In fact, the industry has articulated a principled stance in defence of its intellectual property rights (in opposition to the proposal) and promised to legally challenge any introduction of such legislation.
Are tobacco companies entitled to the same protection offered by New Zealand law as any other business? The decision of the High Court of Australia to allow plain packaging certainly sets a persuasive precedent, and many legal commentators have since weighed in with their thoughts.
However one point missed by most commentators is that regardless of how much of a legal fight the tobacco industry puts up, and even how strong its legal position might be, the New Zealand judiciary has very limited power to override the clear intention of Parliament.
This has been shown in the courts before. One example can be found in the High Court's decision in the 2000 retrial of Teina Pora.
It is a fundamental principle of law that a heavier penalty cannot be imposed than the one applicable at the time the offence was committed. Yet, the government of the time, as a result of public sentiment after a spate of high profile home invasion cases, legislated to increase non-parole periods from 10 years to 13 years for home invasion murders, even if committed before the commencement of the new legislation.
No amount of judicial interpretation enabled the High Court in December 2000 to avoid applying the Crimes (Home Invasion) Amendment Act 1999 and the Criminal Justice Amendment Act (No 2) retrospectively.
In that decision, Justice Keith delivered the majority opinion, stating that Parliament's words and purpose were so plain that breaches of our Bill of Rights Act could not be removed by judicial interpretation.
Courts in New Zealand have always been reluctant to be interventionist or act as social engineers. Unlike in Australia and the United States which both have a written constitution, our legal and political system does not give our Supreme Court latitude to decide on social issues like plain packaging.
The one glimmer of hope is that the Prime Minister has indicated the Government would be guided by any ruling issued by the World Trade Organisation.
But in the absence of this, it seems the tobacco industry might be ultimately unsuccessful in any legal action to prevent plain packaging.
One thing is clear: the plain packaging debate demonstrates that intellectual property rights in the form of trademarks are powerful marketing tools indeed.
Why else would the tobacco industry fight so vehemently to retain them?
