Government may respond to controversial issues by formulating and implementing unpopular policies such as to avoid democratic review before a point of no return.

In the UK the government was accused in 1993 of endeavouring to privatize the health service by stealth and of endeavouring to impose a country-wide pattern of expressways without appropriate consultation.
