There is also a law on the working order of the Parliament with a special status but which does not qualify as a "fundamental law", although certain parts of it are harder to change than ordinary laws:
To amend or to make a revision of a fundamental law, the Parliament needs to approve the changes twice in two successive terms, with a general election having been held in between. The change can be dismissed but not formally approved by a popular vote coinciding with such a general election, although this option has never been utilised. If the people do not dismiss a change, it still has to be ratified by the newly elected Parliament.
The parliamentarian Instrument of Government of 1974 grants the power to commission a Prime Minister to the Parliament (Riksdag) at the suggestion of the Speaker of the Riksdag. The Prime Minister appoints members of Cabinet including heads of ministries, totalling to approximately 22 members. The Cabinet decides collectively in governmental matters after report of the Head of Ministry in question. At least five Cabinet members are to be present at the decision. In practice reports are written, and discussions very rare, during the formal Cabinet meetings.
Remaining constitutional functions for The Head of State, i.e. the King, include: heading the Council of State (the King plus the Cabinet), heading the Council on Foreign Affairs, recognizing new Cabinets (in the Council of State), and opening the Parliament's yearly session. The King is to be continuously briefed on governmental issues – in the Council of State or directly by the Prime Minister.
The first constitutional Instrument of Government was enacted in 1719, marking the transition from autocracy to parliamentarism. Sweden's bloodless revolution of 1772 was legitimized by the Parliament in new versions of the Instrument of Government (in 1772 and 1789), making the King a "Constitutional Autocrat". When Sweden was split in 1809, and the Grand Duchy of Finland was created as an autonomous part of the Russian Empire, this "Constitutional Autocracy" was very well fitted and remained in force until Finland's independence in 1917.
In Sweden the loss of virtually half the realm led to another bloodless revolution, a new royal dynasty, and a new Instrument of Government of June 6, 1809 (as well as a new Freedom of Press Act and Act of Succession), under which the King still played a central role in government, however no longer independent of the Privy Council. The King was free to choose Councillors, but was bound to decide in governmental matters only in presence of the Privy Council, or a subset thereof, and after report of the Councillor responsible for the matter in question. The Councillor had to countersign a royal decision, unless it was unconstitutional, whereby it gained legal force. The Councillor was legally responsible for his advice and was obliged to note his dissension in case he did not agree with the King's decision. De jure this Constitution puts a considerable power on the King; a power increasingly used to follow the Councillors' advice, and, from 1917, to adhere to principles of parliamentarism by choosing Councillors possessing direct or indirect support from a majority of the Parliament.
After over 50 years of de facto parliamentarism it was written into the Instrument of Government of 1974 which, although technically adherent to Constitutional monarchy, finally abolished the Privy Council.
Sweden's switch from elective to hereditary monarchy in 1544 gave reason to Sweden's first law of constitutional character, in form of a treaty between the royal dynasty and the realm represented by the four Estates to be valid for all times.
Accordingly the current 1810 Act of Succession (Successionsordningen, SO) is a treaty between the old Riksdag of the Estates and the House of Bernadotte regulating the right to accede to the Swedish throne. In 1980 the old principle of "agnatic primogeniture", which meant that the throne was inherited by the eldest male child of the preceding monarch, was replaced by the principle of "equal primogeniture." This meant that the throne will be inherited by the eldest child without regard to sex. Thereby Princess Victoria, the eldest child of King Carl XVI Gustav of Sweden, was created heiress apparent to the Swedish throne over her younger brother, until then Crown Prince Carl Philip.
The Freedom of the Press Act (Tryckfrihetsförordningen, TF) has actually been changed several times since its first incarnation. In 1772, 1810, 1812, 1949 and 1982. It was not, however, until the 1810 Act that what we today generally call freedom of expression was secured. The 1766 Act held for example that freedom of expression was to be uninhibited, except for "violations", which included blasphemy and criticism of the state.
The Fundamental Law on Freedom of Expression (Yttrandefrihetsgrundlagen, YGL) of 1991 is a lengthier document defining freedom of expression in all media except for written books and magazines (such as television, the Internet, radio, etc.)
This list is exhaustive and the Parliament may not legislate about restrictions outside the scope of this list, and any restrictions have to be legislated into the Secrecy Act previously mentioned. Secrecy is limited to a maximum time of 70 years (when relating to individuals that is 70 years after the person's death).
In 1593, after 70 years of Reformation and Counter-Reformation in Sweden, adherence to the Augsburg confession was decided and given constitutional status at the Synod of Uppsala (Uppsala möte). References to Uppsala möte have since then been worked into the fundamental laws, notably the Act of Succession.
In 1999 the Church was separated from the state and became an independent organization, but the ruling body of the church is still decided by public voting (among members of the church), and mostly consists of the political parties. As a result of this separation, people born in Sweden where the parents are members of the Church of Sweden since 1999 no longer become members of the church automatically at birth.
