Demotion
Although they won the promotion play-offs, Swindon Town did not compete in the First Division during the following season. The 1989–90 season had seen the club charged with 36 breaches of Football League regulations – 35 of which related to illegal payments made to players between 1985 and 1989. A hearing to decide the club's fate was scheduled for 4 May – before the play-offs began – but this was postponed on legal advice just days before it was due when Swindon chairman Brian Hillier, club accountant Vince Farrar and former team manager Lou Macari were all charged by police for "intent to defraud Inland Revenue by making payments without deducting tax or NI".. Hillier and Macari had already been punished by the FA in February 1990 for their involvement in a £6,500 bet being placed on Swindon losing to Newcastle United in a tie during the 1987–88 FA Cup. The bet was successful and netted £4,000 winnings. As this activity ran counter to FA rules that forbid any bets by club officials or players on their own team, both were found guilty. Hillier was given a six-month suspension from football, but after he appealed, the FA increased it to three years. Macari was fined £1,000, and Swindon Town given a £7,500 fine. At a Football League hearing on 7 June, Swindon pleaded guilty to all 36 charges against them and admitted a further twenty. The league decreed that the club would be denied promotion and instead demoted to the Third Division. Six days later, it was announced that losing play-off finalists Sunderland would be instead promoted to the First Division. This was controversial as Newcastle felt that as they had finished third, three places above bitter rivals Sunderland, they should have been promoted instead. The FA's decision stood and Sunderland were promoted. Swindon launched a High Court appeal against the Football League's double demotion, claiming it to be "harsh, oppressive and disproportionate to previous penalties". However, within days they dropped this action and instead appealed directly to the FA. On 2 July an FA Appeal Panel reduced the punishment to the club simply remaining in the Second Division; Tranmere Rovers – the losing play-off finalists in the Third Division – who were to have replaced Swindon in the second level were therefore denied promotion.
