 systems, an election threshold is a clause that stipulates that a party must receive a minimum percentage of votes, either nationally or within a particular district, to obtain any seats in the parliament. The effect of the threshold is to deny small parties the right of representation or force them into coalitions, with the presumption of rendering the election system more stable by keeping out radical factions. It is also argued that in the absence of a preferential

n parliamentary elections of 1992 and 1996 the threshold was set at 3 parliamentary seats. This meant that the parties needed to win about 3.2% of the votes in order to pass the threshold. In 2000 the threshold was raised to 4% of the votes.

In Sweden, there is a nationwide threshold of 4%, but if a party reaches 12% in one election district, it will be represented even if it does not reach the 4% level nationally. However, through the 2010 election, nobody has been elected based on the 12% rule. In Norway

, as the majority of elections are conducted under the first past the post system, election thresholds do not apply in the actual voting. However, several states have threshold requirements for parties to obtain automatic ballot access to the next general election without having to submit voter-signed petitions. The threshold requirements have no bearing on the two main political parties (the Republican and Democrat Parties) as they easily meet the requirements, but have come into play for minor parties such as the Green and Libertarian Parties. The threshold rules also apply for independent candidates to obtain ballot access.

Countries can have more than one threshold. Germany, as mentioned earlier, has a "regular" threshold of 5%, but a party winning three constituency seats in the Bundestag can gain additional representation even if it has achieved under 5% of the total vote. Most multiple-threshold systems are still in the proposal stage. For example, in Canada
