Hall was embarrassed that the LCL was even in a position to govern despite having been convincingly defeated in terms of actual votes. The outcry over this result led Hall to institute electoral reform in 1968. The House was expanded to 47 seats—28 in Adelaide and 19 in rural areas, an increase of 15 metropolitan seats, more than double. It fell short of "one vote one value", as Labor had demanded, since country areas were still somewhat over-represented. Not only did it not take into account that Adelaide accounted for two-thirds of the state's population, but the most populous metropolitan seats still contained double the number of voters than the least populous rural seats. However, even with this slight rural weighting, Adelaide now elected a majority of the legislature. Given Labor's dominance in Adelaide over the past three decades, the conventional wisdom was that Hall knew he was effectively handing the premiership back to Dunstan at the next election. When a snap election was called in 1970, Labor gained power as expected, with 53.3 percent of the two-party vote.
