The Swedish Parliament consists of two institutions (that also are two separate buildings): the house of Lords (Ridderskapet och adeln), where all the comital, baronial and noble houses are represented through the heads of every house (or, if the head is unable or unegilible to represent the house, e.g. if he is under age or is living abroad, the egilible person being closest in line to become head), and the house of commoners (Allmänna riksdagen). There are elections to the house of commoners every fourth year, on the second sunday in September (next election is scheduled for 14 September 2014). To be allowed to vote to the house of commoners you have to be a Swedish citizen, be eighteen years or older on the day of the election, have an income or own capital, either in the form of money or as property, and not depend on benefits or owe taxes. Each voter has from one to forty votes, depending on their income and capital. To be able to be elected a member of the house of commoners, you need to meet the same requirements.
The house of commoners consists of 549 members. The number of members of the house of Lords depends on the number of noblemen, Barons and Counts egilible to become members there.
Both the house of commoners and the house of Lords vote on laws. For a law to pass, both the house of Lords and the house of commoners must vote yes on it, and the King must not use his veto against it. Otherwise, the law falls.
