The Saeima has 100 members, elected for a four-year term by proportional representation with a 5% threshold.
In certain cases the President or one third of members of the Parliament have the right to suspend the proclamation of a law for a period of two months.
It forbids issues like budgets, taxes, military conscription, declarations of war, peace treaties, agreements with other nations, etc.
One tenth of the electorate can request amendment of the Constitution or adoption of a law.
The exception is decisions regarding Latvia's membership of the EU or substantial changes in the terms of membership of the EU - those measures need a voter turnout of 50% of the number of voters who participated in the last elections for the Parliament.
