Labor won two seats from the Liberals, the districts of Adelaide (Jane Lomax-Smith) and Colton (Paul Caica). This gave Labor 23 seats, Liberals 20 seats, SA Nationals one seat, and three seats to independents. To form majority government, a party needed 24 seats out of 47. Most analysts expected Kerin to form a minority government with the support of Nationals MP Karlene Maywald, and the three independents, who were all former Liberal party members.

On 13 February, one of those crossbenchers, former Liberal Peter Lewis, announced that he had signed an agreement with Labor leader Mike Rann to support a Labor Government in exchange for holding a constitutional convention, making him speaker of the House of Assembly, and concessions for his electorate including the phasing out of commercial fishing in the River Murray, prioritising the eradication of the branched broomrape weed, changing water rates for irrigation, fast-tracking a feasibility study for a weir and lock at Wellington, and improving rural roads. This agreement effectively made Rann premier-elect by one seat.

However, following parliamentary precedent established by Don Dunstan following the 1968 election, Kerin refused to resign until Rann and Labor demonstrated that they had majority support on the floor of the House of Assembly. Kerin claimed to be within this rights to take this course, as longstanding precedent in the Westminster system holds that the incumbent premier should have the first opportunity to form a government if no party has a majority.

After three weeks of stalemate, the House of Assembly was called into session several weeks earlier than usual. With Lewis in the speaker's chair, the Kerin Government was defeated on the floor of the House of Assembly on 5 March 2002, after Kerin moved a confidence motion in his own government and lost. Rann then advised Governor Marjorie Jackson-Nelson that he could form a government, which was duly sworn in the following day.

Rann later shored up his government's majority by reaching agreements with crossbenchers Maywald and McEwen, giving them cabinet posts in exchange for their support of the government.

In the Legislative Council, Liberal won 5 seats (Robert Lawson, Caroline Schaefer, Angus Redford, David Ridgway, Terry Stephens), Labor won 4 seats (Gail Gago, Paul Holloway, Terry Roberts, John Gazzola), Australian Democrats won 1 seat (Sandra Kanck), and the recently formed Family First party won their first ever seat in an Australian parliament (Andrew Evans).

This left the overall numbers in the Legislative Council at: Liberal 9, Labor 7, Democrats 3, Family First 1, No Pokies 1, and 1 independent (Terry Cameron).
