The league was scaled up to 18 teams, after the Court's rule to nullify Boavista's relegation from the Primeira Liga in the 2007–08 season.
Boavista has been invited back in the Primeira Liga, after the club won a legal battle that eventually deemed their forced relegation five years ago unlawful.
The club therefore went straight from the third level to the top league.

The league is named Liga NOS since 5 February 2015.
