Voter-initiated referenda' refers to the following process. First, citizens gather signatures for a petition in favor of a certain bill. If the petition gets enough signatures (usually 5-10% of the population), the law is put before the voters. If a majority of voters vote in favor of the bill, it becomes a law. This allows citizens to enact legislation without any involvement from Parliament or any politicians. If voter-initiated referenda are allowed, parliament could still pass other laws without this process, but parliament would be bound to the decision of the referendum.
