Clubs that are successful in their league can rise higher in the system, whilst those that finish at the bottom can find themselves sinking further down.
In theory it is possible for any club's first team to rise to the pinnacle of shinty and become champions of the Premier Division.
The Camanachd Association board of directors discussed the future of the league structure in December 2010 with a reduction of the Premier Division to 8 teams being mooted.
[5] What resulted by 2013 was a controversial return to a National Division model with a reduction in the number of teams in the Premiership to 8 from 10.
This development caused a great deal of controversy and resulted in a fiery Special General Meeting which saw the Board use company law to ensure that the required 75% majority to overturn the decision was not achieved.
Despite an effort from Oban to have both teams playing in the one league, the Camanachd Association offered the opportunity for promotion to Glasgow Mid Argyll.
