As Tayler (2003) mentions, demutualisation moves succeeded immediately because neither Conservative nor Labour party UK governments created a framework which put obstacles in the way of demutualisation. Political acquiescence in demutualisation was clearest in the case of the position on 'carpetbaggers', that is those who joined societies by lodging minimum amounts of £100 or so in the hope of profiting from a distribution of surplus after demutualisation. The deregulating Building Societies Act 1986 contained an anti-carpetbagger provision in the form of a two-year rule. This prescribed a qualifying period of two years before savers could participate in a residual claim. But, before the 1989 Abbey National Building Society demutualisation, the courts found against the two-year rule after legal action brought by Abbey National itself to circumvent the intent of the legislators. After this the legislation did prevent a cash distribution to members of less than two years standing, but the same result was obtained by permitting the issue of 'free' shares in the acquiring plc, saleable for cash. The Thatcher Conservative government declined to introduce amending legislation to make good the defect in the 'two-year rule'.
