The Kingdom of Sweden has four grundlagar — constitutional acts that rank above ordinary statute and can only be amended by two consecutive Riksdag votes with an intervening general election. They are the Instrument of Government (Regeringsformen), the Act of Succession, the Freedom of the Press Act (Tryckfrihetsförordningen, TF, 1766, last comprehensive revision 2018) and the Fundamental Law on Freedom of Expression (Yttrandefrihetsgrundlagen, YGL, 1991). The last two are the ones a hosting provider lives under.
TF is the older document — older than the United States Constitution, older than the French Revolution, older than the Bill of Rights. It was enacted on 2 December 1766 under King Adolf Frederick and codified, for the first time in any continuously functioning legal system, freedom of the press as a positive right. The 2018 revision modernised the language and expanded the scope to cover modern printing and distribution; it did not weaken the core guarantees. YGL was added in 1991 to extend the same regime to "technical recordings" — radio, television, video, websites — that did not exist when TF was drafted.
The clause that matters most to an infrastructure operator is källskydd — source protection — codified at TF Chapter 3. § 1 obliges anyone who receives information for publication to protect the source's identity. § 3 forbids disclosure without consent, except in narrow enumerated cases (typically grave crimes against the realm, listed exhaustively). § 4 prohibits public authorities from investigating who a source was. § 5 makes unauthorised disclosure a criminal offence punishable by fine or imprisonment. The combined effect is rare in European law: the operator is criminally liable for breaking source secrecy, and the state is criminally constrained from even asking.
YGL extends the same architecture to electronic publication. The strongest tier of YGL protection — formal designation as a publication with a responsible publisher (ansvarig utgivare) and an utgivningsbevis issued by the Myndigheten för press, radio och tv — is opt-in. Sites without a certificate still benefit from baseline YGL principles and from general European press-freedom case law, but the certificated regime is the most explicit shield available on the open market. NordBastion does not file utgivningsbevis on behalf of customers; this is a project-level decision the customer makes in their own name when it fits.
