In Switzerland, as in all democratic countries, citizens elect representatives to act on their behalf.

But Switzerland gives its citizens the chance to take a direct part in decision-making as well. Although direct democracy is by no means unique to Switzerland - Italy and many US states are among those who also give voters an important decision-making role - the Swiss system is probably the most extensive in the world.

Swiss citizens can both propose legislation of their own, or thwart legislation already approved by parliament.

The only case in which parliament can override this right is if it decides that the motion being proposed is unconstitutional, or if it violates international law.
