here is a refined idea for a party system with example:
it seems to give the independant candidates good chances to go to parliament
1) the parliament will consist of 1/3 of the active citizenry
2) each official party has to define a list of "representatives" in the order of priority before the election starts
3) the regular elections will define the values used to "split" the parliament between the candidates
4) independant candidates will receive their seat if they would get at least one full seat in the parliament according to the percentage in the elections
5) the remaining seats are distributed among the official parties according to their relative percentages against each other. only full seats count
6) if any seats are left empty, independant candidates are filling them up according to their percentages
example:
active citizenry: 30 => parliament size:10
party1's List: A,B,C,D,E,F,G,H,I
party2's List: J,K,L,M,N,O,P
independant candidates: X,Y,Z
so the election would be to choose between: party1, party2, X, Y, Z
result:
party1: 50%
party2: 25%
X: 5%
Y: 8%
Z: 12%
so now the independant candidates:
X would get 5% of 10=0.5 seats=> not directly in parliament
Y would get 8% of 10=0.8 seats=> not directly in parliament
Z would get 12%of 10=1.2 seats=> DIRECTLY IN PARLIAMENT!
so there would be 9 seats left
now to the parties:
relative percentages:
party1: 66%
party2: 33%
which means:
party1=66%of9 = 5.94 = 5 seats
party2=33%of9 = 2.97 = 2 seats
this would mean that the citizens A,B,C,D,E, J,K would be in parliament
which would leave 2 seats open, so:
the independant candidates X and Y also go into parliament INDIRECTLY.
the parliament would be:
A,B,C,D,E,J,K,X,Y,Z
