for 26 years. In the latter part of Playford's tenure, the LCL could only hope to win a few seats in Adelaide. However, the LCL's grip on the country areas was such that it was able to retain power when it lost by substantial margins in terms of raw votes. Labor finally overcame the Playmander at the 1965 election under Frank Walsh, but the malapportionment was strong enough that Labor only won 21 seats—just enough for a majority—despite taking 54.3 percent of the two-party vote. At the 1968 election, Labor, now led by

. Hall was embarrassed that his party was in a position to win power despite finishing seven points behind Labor on the two-party vote. Concerned by the level of publicity and public protest about the issue, Hall was committed to the principle of a fairer electoral system. He enacted a system that expanded the House of Assembly to 47 seats—28 of which were located in Adelaide, an increase of 15 metropolitan seats, more than double. The reforms fell short of "

," as Labor had demanded, since country areas were still somewhat over-represented, with the most populous metropolitan seats still containing double the number of voters than the least populous rural seats. However, while there was still rural overweighting, Adelaide now elected a majority of the legislature, making it a near-certainty that Labor would win the next election. Conventional wisdom was that Hall was effectively handing the premiership to Dunstan at the next election. A 1968 Millicent by-election was triggered by the Court of Disputed Returns where Labor had won the seat by a single vote at the 1968 election. Labor increased their margin. Notably, turnout increased at the by-election. In early 1970, Hall and Stott fell out over the location of a dam. Stott wanted the dam built in his electorate while Hall thought it more use to locate it elsewhere. Constituent anger forced Stott to vote against the Hall government, leading to an early election and the expected loss to Labor. Stott did not contest the 1970 election. Hall remained Leader of the Opposition for two years before resigning from the LCL, claiming that the Party had 'lost its idealism ndforgotten...its purpose for existence'. He founded the Liberal Movement, a progressive Liberal party that included about 200 former LCL members. Hall won a Federal Senate seat for the Liberal Movement in 1974 (and was re-elected in 1975), serving in the Senate for three years before resigning his position.
