The 1982 edition, while maintaining the previous system of two-tier divisions, exceeded in creativity by introducing for the first time the feature of internal relegation. As for the internal promotion, teams from first-division first phase would be relegated entering second-division's third phase, only to be able to still fight for a place in the second-division finals and thus guarantee promotion to following-year's first division. It was probably the first and unique example of "cross internal promotion and relegation" where teams starting on first division could end up second-division champions and teams of second division could end up first-division champions within the same season.
