 The "Bairns" were angered when Inverness Caledonian Thistle, who already had a new stadium but not of sufficient size, were allowed to join the SPL for the 2004–05 campaign on a ground-sharing agreement with Aberdeen (100 miles away from their home city), albeit only for six months during expansion work, when Falkirk had been denied such an arrangement with Clyde or Airdrie United the year before.This developments caused further annoyance for Partick Thistle as they were the club relegated from the top division when Inverness made their Aberdeen plan.That summer, a reduction in the required seating capacity from 10,000 to 6,000 came into effect, which benefitted clubs such Inverness, Falkirk (who gained promotion in the first season in their new stadium) and later Hamilton, as smaller new venues were now acceptable without even having all four sides built up (to reach the lower threshold in 2008, Hamilton erected a 'temporary' stand for 700 which was still in place a decade later).
