The Swiss Football Association (ASF/SFV) had 28 member clubs at this time and these were devided into two divisions of 14 teams each.
The champions would qualify for the 1967–68 European Cup and the last two teams in the league table at the end of the season were to be relegated.
After 88 minutes of play, with the score at 1–1, referee Karl Göppel awarded Basel a controversial penalty.
André Grobéty had pushed Hauser gently in the back and he let himself drop theatrically.
Subsequent to the 2–1 for Basel the Lausanne players refused to resume the game and they sat down demonstratively on the pitch.
Because two teams ended the season level on points in joint twelfth position a decider against relegation was required.
