Should packaging rules intended to improve the nation's health, or the freedom of business to exploit its intellectual property, hold sway?  This question will never go away (and nor should it), as getting this balance right is an essential test of a democracy.  Much depends on how much we trust the Government of the day to get the judgement right as to what is in the public interest, and with the reputation of politicians coming on for a bit of a battering in recent years, the Government will be under constant pressure to defend that judgement.
